NSA/MWRP/C1 - Calibration drift

The radiometer showed increased drift in the K-band calibration. Several attempts to 
correct for the drift did not return the expected result.

• Water vapor, total precipitable, derived from Tbright using stat. retrvl.(totalPrecipitableWater)
• Height, lifting condensation level(liftingCondensationLevel)
• Temperature, virtual, vert. prof. sfc-10km, fr. wtr. vap. dens. and temp. prof.(virtualTemperature)
• Height, level of free convection(levelFreeConvection)
• Density, water vapor, prof. from sfc.-10 km, der. from Tbright stat. retrvl.(waterVaporDensity)
• Humidity, relative, prof. from sfc.-10km, from water vap. dens. and temp. prof.(relativeHumidity)
• Liquid water content, cloud, vert. prof. sfc.-10km, from Tbright stat. retrvl.(liquidWaterContent)
• Microwave brightness temperature(brightnessTemperature)
• Liquid water path, from brightness temperatures using statistical retrieval(liquidWaterPath)
• Liquid water path, from Tbright at 23.835 and 30.0 GHz only, using stat. retrvl.(liquidWaterPath2)
• Water vapor, tot. precipitable, from Tbright, 23.835 & 30.0 GHz, stat. retrvl.(totalPrecipitableWater2)
