FKB/MWRP/M1 - Heavy rain and fog at the site
DataStreams:fkbmwrpM1.b1
Description:
The months of November and December have been very rainy and wet at the AMF site. During 
rain events the radiometer does not work properly because of water accumulating on the 
window. In addition condensation and fog will affect the data causing very high brightness 
temperatures. Although the instrument is equipped with rain detection system to flag bad 
data, it is important that the user pays extra attention to the quality of the data during 
periods of continuous rain, drizzle or fog by applying the quality checks and screening 
for high brightness temperatures.
Suggestions:
