MeteoShield Pro – Barani Design’s helical solar radiation shield for windless sunny and snowy conditions – is the culmination of feedback from users in Antarctica, the Swiss Alps and Death Valley in Nevada.
Improvements in measurement accuracy have been achieved within this design, particularly in entirely windless weather conditions, in places with lots of surface reflections from snow or where the ground gets too hot during the day. These improvements are the result of increasing natural airflow around internal sensors and better management of light reflections from below. Although the changes may seem subtle to the naked eye, they help users in sunny and snowy locations reduce measurement uncertainty to below 0.1°C.
The third generation of the solar radiation shield also enables the addition of a solar-powered fan, without the risk of compromising its naturally ventilated performance for locations where wind speeds tend to stay below 0.5m/s.
