TWP/MWR/C2 - Reprocessed: New Calibration coefficients
DataStreams:twpmwrlosC2.b1, twpmwrtipC2.a1
Description:
On 11/27 a spare radiometer was installed to replace a faulty radiometer. Once the 
radiometer started to collect data it used the default calibration coefficients until it 
collected enough tip data to determine its own coefficients.

The data were reprocessed to apply corrected calibrations and the reprocessed data were 
archived 20061222.
