Subject:
HFE/MWRHF/M1 - Calibration updates
DataStreams:hfemwrhfM1.b1
Description:
The MWRHF calibration algorithm updates the calibration parameters every time a new 
successful tip curve is acquired. 

This results in small jumps (1-2 K) in the brightness temperatures each time calibration 
is updated. During times of frequent calibrations the data appear discontinuous with short 
data segments interrupted by small jumps.
Measurements:hfemwrhfM1.b1:
  • 90.0 GHz sky brightness temperature(tbsky90)
  • Sky brightness temperature (150 GHz)(tbsky150)

Subject:
HFE/MWRHF/M1 - Rain sensor failure
DataStreams:hfemwrhfM1.b1
Description:
The rain sensor failed and the rain flag was always on.  When the rain flag is on the 
radiometer does not perform tip curves. The rain sensor was replaced 8/4.
Measurements:hfemwrhfM1.b1:
  • Rain flag(rain_flag)
