MAO/CEIL/M1 - missing window blower
DataStreams:maoceilM1.b1
Description:
The window blower was missing from the VCEIL at deployment and could not be found. A new 
unit was ordered and installed. Data may be affected during periods of high humidity, 
condensation, and precipitation.
Measurements:maoceilM1.b1:
  • Cloud, base height, second lowest base sensed(second_cbh)
  • vertical_visibility
  • Third cloud base height(third_cbh)
  • Cloud, base height, lowest base sensed(first_cbh)

MAO/CEIL/M1 - Power outage, UPS overload
DataStreams:maoceilM1.b1

Subject:
MAO/MWRP/M1 - Reprocess: High precipitable water vapor
DataStreams:maomwrpM1.b1
Description:
The precipitable water vapor appears to have a high bias that appears to be due to 
brightness temperatures being calibrated 1.5-2 K too warm. 
The reason for the calibration bias is not known and several attempts at correcting it 
have not been successful. The liquid water path is not affected as much.
Measurements:maomwrpM1.b1:
  • Water vapor, tot. precipitable, from Tbright, 23.835 & 30.0 GHz, stat. retrvl.(totalPrecipitableWater2)
  • Water vapor, total precipitable, derived from Tbright using stat. retrvl.(totalPrecipitableWater)
