Subject:
SBS/MWR/M1 - Reprocessed: Incorrect retrievals
DataStreams:sbsmwrlosM1.b1
Description:
The PWV and LWP retrievals at this site were incorrect for lack of radiosonde data.

At the end of the deployment, the mentor provided new retrieval coefficients and the 
MWRLOS data were reprocessed and archived.

The MWRTIP data have not yet been reprocessed.	The correction of these data are in the 
reprocessing queue at a low priority.
Measurements:sbsmwrlosM1.b1:
  • Water, liquid, total along line-of-sight path(liq)
  • Total water vapor along LOS path(vap)

SBS/MWR/M1 - Temperature instability
DataStreams:sbsmwrlosM1.b1
Description:
The radiometer was thermally unstable due to the extremely cold outside temperature.  Data 
are suspect.
Measurements:sbsmwrlosM1.b1:
  • Water, liquid, total along line-of-sight path(liq)
  • Mean 31.4 GHz sky brightness temperature(tbsky31)
  • Total water vapor along LOS path(vap)

SBS/MWR/M1 - Instrument problem
DataStreams:sbsmwrlosM1.b1
Description:
The fan in the dewblower malfunctioned from 3/11 to 3/30. During this time it is likely 
that snow deposited on the radome during snowfall events and it stayed on the radome longer 
than usual.
