Subject:	HFE/MWR/M1 - Insufficient calibration stability
DataStreams:	hfemwrlosM1.b1, hfemwrtipM1.a1
Description:	The noise diode temperature suddenly jumped to > 60 C after a power outage. Following additional power problems the noise diode injection temperature drifted fast and the radiometer was not able to calibrate properly. Data during the indicated time periods are poorly calibrated and sometimes erratic. Users should be aware that the accuracy of the measurements is dramatically degraded. Users can use the microwave profiler (MWRP) data to supplement the MWR data.

Subject:	HFE/MWRP/M1 - Reprocess: Bias in LWP retrievals
DataStreams:	hfemwrpM1.b1
Description:	Since local radiosondes were not available, radiosondes from a different site were used to develop retrieval coefficients. LWP retrievals are biased in the summer months (June-September). Data in May and December are not affected. Additional analysis will be conducted to derive new retrieval coefficients and the data will be reprocessed.
Measurements:	hfemwrpM1.b1: Liquid water path, from Tbright at 23.835 and 30.0 GHz only, using stat. retrvl.(liquidWaterPath2) Liquid water path, from brightness temperatures using statistical retrieval(liquidWaterPath)
