SGP/MWR/C1/E14 - Freezing rain-Incorrect rain flag
DataStreams:sgpmwrlosC1.b1, sgpmwrlosE14.b1, sgpmwrtipC1.a1, sgpmwrtipE14.a1
Description:
Between 01/12 and 01/15 brightness temperatures show high values (Tb > 100 K) indicative 
of rain, however the wet_window flag is 0 (indicative of no rain). During that time there 
where freezing conditions with ice pellets that were not detected by the sensor. The high 
brightness temperatures may be due to melting ice on the window.
Measurements:sgpmwrtipC1.a1:
  • Water on Teflon window (1=WET, 0=DRY)(wet_window)
sgpmwrlosC1.b1:
  • Water on Teflon window (1=WET, 0=DRY)(wet_window)
sgpmwrtipE14.a1:
  • Water on Teflon window (1=WET, 0=DRY)(wet_window)
sgpmwrlosE14.b1:
  • Water on Teflon window (1=WET, 0=DRY)(wet_window)
