The first evaluation of a 6-months automatic Meteodrone campaign

Dr Maxime Hervo
Upper-air network manager
Evaluation of a 6-months Meteodrone campaign at Payerne, Switzerland. 864 automatic flights were evaluated using the co-localized radiosonding and remote sensing instruments. According to the WMO/OSCAR requirement, Meteodrone temperature measurements can be qualified as a “breakthrough”. We also demonstrate that humidity and wind measurements are useful for numerical weather prediction.

Experimental observation of air temperature rise due to the reflection of solar radiation above the clouds

Dr Yong-Gyoo Kim
Principal Research Scientist
This presentation deals with the increase of the local irradiance due to the solar reflection from the top cloud surface, which leads to a phantom increase in radiosonde temperature with a single temperature sensor, and how to correct it based on the dual sensor technique. Experimental results on intercomparison sounding with DTR and RS41 are presented, and I will talk that the measured temperature of RS41 at an altitude above 1 km higher than a cloud layer could be increased by about 2 oC than DTR-corrected actual air temperature.

Topic 1: Innovative measurements, techniques and integration Part Two

Using Machine Learning to Improve Data Quality and Thus Meteorological Decisions and Alerting

Brian Bellew
Global Business Development Manager
The recent expansion of RF communication and other technologies or even naturally occurring phenomena has resulted in interference and distortion within the radar signal. The interference on the radar produces false images that might be interpreted as precipitation. Baron has studied the problem extensively and found that using machine learning, the radar data can be “cleaned.” We will demonstrate how this advanced technology has improved radar imagery and discuss the benefits and importance of clarity in weather radar imagery.

Image-based flow measurements during flood events

Dr Salvador Peña-Haro
CTO, photrack ag
For river basin management it is crucial to have river flow data during flood events events, however flow monitoring under these conditions using conventional intrusive methods is difficult. Image-based discharge measurements provide a flexible and non-intrusive method for flow monitoring especially suitable during flood conditions. In this presentation, image-based methods and the results of three flood events will be presented.

Sustainable rain monitoring using communication links of existing broadband satellite networks

Dr Julian Krebs
Accurate precipitation measurements are crucial for weather prediction and protection of human life. As an alternative to expensive and sparsely deployed weather radars, we propose a novel type of sustainable rain sensors based on existing satellite communication infrastructure. The signal quality of satellite dishes used in broadband services is strongly impaired by precipitation on the communication path. We utilize signal processing and machine learning, to convert the quality signal, already monitored by satellite operators, to create high resolution rain maps.

Cognitive camera enhanced software-defined method for automatic rainfall measurement.

Amul Batra
Scientist 'E'
Ministry of Earth Science, New Delhi
A cognitive model using camera replicating a human subject in taking readings from a remote locations is proposed. To improve the quality and reliability of the images, Artificial intelligence based single image super resolution techniques are explored. Need for the methodologies and met-network IOT protocols to make this type of models self-sufficient, network independent, power aware and replicable is highlighted. This can open up new gateways for the research in unexplored and remote areas and can glare up the unknown facts about environmental changes and challenges in these areas where establishment of a regular observatories are not feasible.

Development of a New Cloud/Precipitation Particle Imaging Radiosonde Using the 400-MHz Meteorological Band

Dr Kensaku Shimizu
Development Engineer
Understanding cloud micro physics is an important subject, but the methods for directly observing particles in clouds are very limited. In Japan, Videosonde and HYVIS, which were developed in the 1990s, however the 1680MHz meteorological aids band used by these is being abolished worldwide for other purposes. To remain this observation technique, new Videosonde (named as Rainscope ) and new HYVIS (named as Cloudscope ) using the 400MHz meteorological aids band have been developed and have conducted initial observation tests. This presentation will explain the details of these instruments.

A new instrument for automatic pollen monitoring networks

Erny Niederberger

In the first part of the lecture, the problem of pollen allergy will be discussed. Then the benefits of automatic pollen monitoring will be shown. Furthermore, the requirements for the instruments of such a monitoring network will be discussed. Finally, a system will be presented which has been developed and successfully used exactly for this purpose: the SwisensPoleno Mars. Current validation results and an outlook on the future of automatic pollen monitoring round off the presentation.

Towards radiatively immune thermometry in weather stations

Dr Laura Bevilacqua
Research Scientist
Radiative heat exchange with thermometers can be a significant source of error in air temperature measurements for weather observations. This presentation will discuss preliminary work towards quantifying and correcting for this type of error. This includes the development of a computational model of a Stevenson screen; using acoustic thermometry as a technique for a radiatively immune reference thermometer; and practical studies of a Stevenson screen both to assess radiative errors of PRTs and to validate the model results.

Transfer Learning with Change Monitoring for Camera-based Snow Detection

Jean-Philippe Andreu
Senior research associate
We are evaluating to what extent an existing visibility range analysis system (visIvis®) is also suitable for snow cover evaluation as a Road Weather Information System. This system working with simple web- cameras was evaluating the snow conditions on road infrastructure. To improve the detection, a dedicated monitoring of changes in image content over time was introduced. It was shown that, in addition to visibility analytics, the visivis® system can be used for snow detection using transfer learning methods.

Using the measured particle size distribution to assess the wind induced undercatch of catching-type gauges

Dr Arianna Cauteruccio
Research fellow
Civil Chemical and Environmental Engineering – Fluid Dynamics and Environmental Engineering
Catching-type precipitation gauges are affected by measurement bias due to wind. A mathematical formulation for the catch ratio of a cylindrical gauge was derived as a function of both wind speed and rainfall intensity. One-minute measurements, obtained at the Hong Kong International Airport field test site where a two-dimensional video disdrometer provides the drop size distribution of the observed rainfall events, were adjusted. The proposed method provides the basis to adjust rainfall measurements for any location and rain event characteristics.

A comparison of precipitation measurement from multiple instruments

Dr Bikas Chandra Bhattarai
Precipitation estimation from the test sensors i.e. Thies-LPM, Ott Parsivel, PWD12 and WS100 are compared with the Geonor T200B reference measurements. As compared with Geonor measurement, all the test sensor under estimate the total amount of precipitation during observation periods. Thies-LPM was more sensitive, recording the higher number of events during test periods. Longer observation from the test sensors in different weather and climatic conditions gives better results in terms of accuracy.

Topic 3: Traceability of measurements to recognized standards

Metrology for aerosol optical properties

Dr Julian Gröbner
Senior scientist
The aim of the project EMPIR MAPP is to enable the SI-traceable measurement of column-integrated aerosol optical properties retrieved from the passive remote sensing of the atmosphere using solar and lunar radiation measurements. In order to validate and improve the current aerosol optical property retrievals using state-of-the-art inversion models, radiometers of the three largest aerosol monitoring networks at NMI laboratories will be calibrated, and portable devices for the in-field calibration of network radiometers will be developed. The goal is to standardise aerosol optical properties retrieval by shortening the calibration chain, reduce calibration downtime of network radiometers and establish their consistent dissemination including their uncertainty.

Wind direction sensor calibration method and procedure

Salih Çakil
Laboratory supervisor
There is no international standard for wind direction sensor calibration. The lack of standard method and reference quide about this area, can be eliminated by sharing the practices and documents of the countries which work on the matter. In order to contribute to the knowledge pool, the calibration method, method and procedures of mechanical wind direction sensors are explained in practice.

Dynamic Characterization of Humidity Sensors Using a Novel H2O Vapor Step Change Generator with Traceable Sampling-free Online Monitoring

Felix Witt
PhD Student
Accurate, time-resolved H2O measurements are highly relevant for weather/climate forecasts i.e. for air-traffic, industry, agriculture or atmospheric research. Here, temporal sensor response characterization is frequently limiting the measurement accuracy in dynamic situations. For improved quantification of the temporal (and static) hygrometer response we developed a novel, metrological, dynamic characterization setup, dynH2O, which combines a H2O vapor step change generator with a traceable sampling- and calibration-free, open-path reference dTDLAS hygrometer and a fluid-dynamics simulation approach to extract the ideal sensor response.

Results, recommendations and challenges of the first ILC campaign at RA-I Africa

Experimental evaluation of the effect of the presence of obstacles in the vicinity of sites hosting near surface meteorological measurement. The case of the road.

Dr Graziano Coppa
PhD, Researcher
The accuracy of meteorological measurements is influenced by the characteristics of the site. To evaluate the effect of the presence of a road on near-surface air temperature measurements, a one-year lasting experiment has been performed, consisting in a 100-m-long array of thermometers with solar shields, placed on a flat field at increasing distances from a road. Statistical analyses have been carried out, showing the influence quantities' combinations maximising the effect, quantified as 1.7±0.4 °C for a return period of 100 years.

Topic 4: Measurement quality assurance and quality control

Measurements uncertainty in meteorology and climatology: joint efforts to improve knowledge

Dr Andrea Merlone
Senior scientist
Uncertainty evaluation is key to understanding data quality in meteorology and climatology. Field conditions, instrumental factors, quantities of influence introduce difficulties in evaluating all parameters to complete the uncertainty budget. Near Surface Temperature measurement is a key example. Recent joint research projects have delivered important results and methods to improve the identification and evaluation of uncertainties, which together with the BIPM, WMO, JCGM joint actions all show the growing interest and efforts. An extended collaborative process, where users, manufacturers, national institutes and services all contribute to increase scientific and technical knowledge in understanding and evaluating measurement uncertainties is here proposed.

Siting Classification – a critical review of member experiences, guidelines for implementations and further development

Dr Mareile Wolff
Associate Professor at Norwegian University of Life Science and Researcher at Norwegian Meteorological Institute
Many weather services have implemented the siting classification (SC) for surface observing stations on land and we have gathered their experience with its application. Users describe the SC as a useful tool for a more objective evaluation of the impact of the surroundings on the meteorological measurements at a site. However, the feedback reveals also challenges counteracting its consistent use. We’ll give guidelines for some common “siting problems” and give an outlook on how to improve and further optimize the SC.

A brief overview of the FSOI methodology will be presented and the results of case-studies quantifying the impact of radiosonde and ship-based data at the individual observing site level will be discussed.

Quality controls applied to opportunistic data for agriculture

Dr Anne-Lise Beaulant
Meteorological Engineer
Meteo France
The close link between weather and agriculture has always pushed farmers to take a strong interest in weather measurements. In the last few years, the number of personal weather stations installed in fields has strongly increased. One can question the quality of these weather stations. Certifying these meteorological data appears as an essential step before any use. We propose to show the interest of implementing procedures for the control of meteorological data, as input to agronomic models.

Analysis of Netatmo Data Quality within the London Model Domain

Matthew Fry
Foundation Scientist
Observation Network Design
Crowdsourced observations from Netatmo home weather stations through the year 2020 were analysed to determine their potential for use in “urban-scale” model validation. Such models have resolutions of the order 25-300 metres, thus requiring observations at vastly greater spatial and temporal densities than are currently available. To assess their potential value, the Netatmo observations were compared against existing Met Office land stations, the WOW citizen observer network, and the 1.5km UKV NWP model, over the London area.

Observations of Atmospheric Carbon Dioxide Concentrations in Hong Kong

Dr Hok-yin Lam

This presentation details HKO's work in CO2 observations, including instrument changes, maintenance and calibration, as well as data quality checking and data archival. Moreover, the trend of CO2 concentration in Hong Kong in the past decade will be analysed and compared with those in other parts of the world. In addition to the long-term trend, the collected data can also help identify short term fluctuations in CO2 concentration. Studies of two episodes with elevated CO2 concentration under specific weather conditions will be discussed.

The 2021 ASOPOS (Assessment of Standard Operating Procedures (SOPs) for OzoneSondes) 2.0 WMO/GAW Report 268: Global Ozone sonde Best Practices

Dr Anne M Thompson
The WMO-sponsored ASOPOS activity has produced new Guidelines for Ozonesonde operations and best practices, summarized in a WMO/GAW Report 268: https://library.wmo.int/index.php?lvl=notice_display&id=21986#.Yz35NkzMJc8. The goal of the “ASOPOS 2.0” Report is for more uniformity in operations and in data processing so the ozone measurement throughout profile can achieve 5% accuracy in the ozone concentration. Important principles in the new Guidelines are (1) more metadata; (2) corrections for pump efficiency errors in the mid-stratosphere; (3) the final ozone record is referenced to a single global standard; (4) continuous comparisons of sonde total ozone must be made with satellite and ground-based data in order detect instrument problems, such as those found in a subset of EnSci instruments since 2013.

Lastly, a summary of our thoughts on going forward is presented.

Tiered networks

Prof Peter Thorne
Update on progression of the concept of tiered network design for WMO. Starting from pre-existing materials a conceptual proposal has been worked up which consists of 4 tiers and the overall defining features have been outlined. Agreements to this conceptual framework is a pre-requisite for implementation. However, it consists of solely a first step and much work would need to be done to subsequently agree criteria for assessment, assessment protocols and embed in regulatory materials. The potential benefits extend across the entire value chain from instrument manufacturers, through network operators to end-users.
