Subject:
AWR/AOSMET/M1 - Poor sensitivity to snow
DataStreams:awraosmetM1.a1, awraosmetM1.01, awraosmetM1.00
Description:
The sensor plate that detects precipitation impact is not sensitive enough to detect snow 
(especially light snow). During the AWR deployment, all precipitation measurements from 
the AOSMETM1 data streams should be carefully considered and compared with colocated 
precipitation measurements.
Suggestions: 
For precipitation rates, use pwd_precip_rate_mean_1min from the AWRMETM1.b1 data 

stream, or precip_rate from the AWRPARS2M1.b1 data stream. Other precipitation quantities 
and weather codes can also be found in those data streams.
Measurements:awraosmetM1.a1:
  • rain_duration
  • rain_amount
  • rain_intensity
