NSA/MWRP/C1 - Reprocessed: LN2 calibration

On 4/9 a spare radiometer was installed at the site. On 4/18 a LN2 calibration was 
conducted. Upon examination of the data it appeared that the LN2 calibration was generally 
successful, however the 30-GHz channel was not calibrated properly.
New calibration coefficients for all K-band channels were derived and data for the whole 
month should be reprocessed with these newly derived coefficients. I will provide the new 
configuration file.

An explanation of the effects of the poor calibration is given in the Instrument Mentor 
Monthly Summary report. The poor calibration affected the LWP in particular. Re-calibration 
will correct the problem.
