At low solar angles, the difference can exceed 0.5 degrees on Barani relative to Apogee. Even when the wind is 2 m/s, when we have the wind on the side of the plates heated by the sun. In addition to sht35, there are PT1000s working in parallel in the shields, which are calibrated. The Pt1000s are connected to loggers with 1s synchronization and averaged measurements up to 1 minute.
The correlation with wind direction and solar operation can be seen clearly. When it blows from the heated surface of the shield even 7-11 km/h, the error occurs, just if it starts blowing from the north or northeast, northwest side of the shield, the error does not occur. Even if it blows 1-1.5 m/s.
Apogee TS-100 as an aspiration shield eliminates radiation errors better than Barani Meteoshield Pro III and other passive shields at relatively low wind speeds.
I think that with each passing week the error on the Barani will get smaller and smaller, as the sun will be higher and higher above the horizon line. Now, under unfavorable conditions, the radiation error on the Barani Meteoshield Pro III persists for most of the day, projecting a t-max against the Davis and Apogee TS-100.
