Subject: | NSA/MWR/C1 - Incorrect brightness temperatures and retrievals |
DataStreams: | nsa5mwravgC1.c1, nsamwrlosC1.b1, nsamwrtipC1.a1
|
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. |
Measurements: | nsa5mwravgC1.c1: - Sky brightness temperature at 23.8 GHz(tbsky23)
- Sky brightness temperature at 31.4 GHz(tbsky31)
- MWR column precipitable water vapor(vap)
- Averaged total liquid water along LOS path(liq)
nsamwrtipC1.a1: - 31.8 GHz sky brightness temperature derived from tip curve(tbskytip31)
- Ambient temperature(tkair)
- Total water vapor along zenith path using tip-derived brightness temperatures(vaptip)
- 23.8 GHz sky brightness temperature derived from tip curve(tbskytip23)
- Total liquid water along zenith path using tip-derived brightness temperatures(liqtip)
nsamwrlosC1.b1: - Averaged total liquid water along LOS path(liq)
- MWR column precipitable water vapor(vap)
- Sky brightness temperature at 31.4 GHz(tbsky31)
- Sky brightness temperature at 23.8 GHz(tbsky23)
- Ambient temperature(tkair)
