Results and conclusions from WMO's Upper Air Instrument Intercomparison 2022

Under the auspices of WMO, Deutscher Wetterdienst (DWD), MeteoSwiss and a wider task team jointly conducted the Upper Air Instrument Intercomparison 2022 (UAII2022). While the focus of the UAII2022 is on radiosonde systems, it also assessed surface-based remote sensing, satellite data and aircraft-based observations. The field campaign of UAII2022 took place in Lindenberg, Germany, from August 8 to September 14, 2022, with 10 participating radiosonde models and a suite of active and passive remote sensing instruments. We present results and conclusions and will announce the public release of the final report.
