NSA/MWR/C1 - Spikes in air temperature readings
DataStreams:nsamwrlosC1.b1, nsamwrtipC1.a1
Description:
During this month there are occasional negative spikes in the Tkair variable. The problem 
may be corrosion in the temperature sensor or the infiltration of water from melting snow.
The dewblower was replaced and a new sensor installed

NSA/MWR/C1 - Incorrect brightness temperatures and retrievals
DataStreams:nsamwrlosC1.b1, nsamwrtipC1.a1, nsa5mwravgC1.c1
Description:
The brightness temperatures and retrieved PWV and LWP show a sudden jump and have values 
that are too high. The suddenly jump back to normal at around 1800 UTC. All other 
parameters seem reasonable so the cause of the jump may just be due to accumulation of either 
snow or melting ice on the radome.

The instrument was covered with a shield to test the effect on the RF interference that is 
affecting the measurements since February. The test was performed on 4/15 and 4/16 for a 
few hours.

NSA/MWR/C1 - High noise in 23.8-GHz channel
DataStreams:nsamwrlosC1.b1, nsamwrtipC1.a1
Description:
Starting approximately on February 13 the MWR experienced high level of noise in the 23.8 
GHz channel. The spikes became more prominent around Feb 17 and increased after that date 
as well. The cause of the interference was identified as the nearby MWRP on Oct 13 and 
the instruments were realigned.
