SGP/DL/C1 - Power supply issue

The supply voltage from the external power supply was running low due to overheating. As a 
result, the instrument was intentionally shutdown for the long Memorial Day weekend.

SGP/MWR3C/E39 - Condensation on lens

The dewblower was malfunctioning and there was condensation on the lens when the RH was 
higher that ~80%.

SGP/MWR3C/E37 - Uncertain IRT data

The IRT data appear to disagree with the co-located MET IRT.

SGP/MET/E13 - False corrected precipitation values

A program bug allowed for maintenance tips to be recorded as precipitation in the 
tbrg_precip_total_corr variable.

• Corrected total precipitation measured by TBRG(tbrg_precip_total_corr)

SGP/MWR3C/C1 - Reprocess: Incorrect temperature coefficient

The 30 GHz temperature correction coefficient has slightly changed. This results in a 
diurnal temperature dependence of the brightness temperature and retrievals.

SGP/MET/E37 - Temperature/humidity sensor not calibrated annually

The temperature/humidity sensor was not calibrated annually during this time, but passed 
all 6-month field calibration checks. Comparison with a nearby Mesonet site suggests the 
relative humidity may be reading low, especially in high humidity situations. An exit 
calibration will characterize severity when the sensor is replaced.

In general, the relative humidity may have been subject to drift during this time. The 
manufacturer characterizes sensor drift at <1% / year.
