| Subject: | SGP/MWR/B1 - 23.8-GHz brightness temperature slightly high |
| DataStreams: | sgpmwrlosB1.b1, sgpmwrtipB1.a1, sgp5mwravgB1.c1 |
| Description: | The radiometer was refurbished and tested at the central facility in 2007. During testing the 23.8-GHz brightness temperature was found to be about 1.5 K higher than the measurements of the C1 radiometer. On 6/19/07 the radiometer was installed at BF1. A comparison with model calculation showed that the measured 23.8-GHz brightness temperature is slightly higher than the model. This offset will affect the PWV retrieval that is on an average about 1.3 mm higher than the radiosonde measurements. The rms error of the retrieved PWV is about 1 mm higher than specified in the netcdf file. On 10/16/2009 the radiometer was removed because of shut down of the boundary facility. |
