SGP/MWRHF/C1 - Dew formation on window

During night time, when the humidity is very high (RH ~ 100%) data are strongly affected 
by
dew formation on the window. 
This results in a smooth and large (80-150 K) increase of the brightness temperature from
early night to sunrise. Data are affected mostly at night.

The user should visually inspect the data before using them. Data that appear to be
		contaminated by dew formation (mostly during night time) should be
		disregarded. Some examples of these data are shown in the instrument mentor
		monthly report.

• Sky brightness temperature (150 GHz)(tbsky150)
• Sky brightness temperature (90 GHz)(tbsky90)
