Subject:	FKB/MFRSR/M1 - Reprocessed: Calibration error
DataStreams:	fkbmfrsrM1.a0, fkbmfrsrM1.b1
Description:	Incorrect calibrations were originally applied to these data. The data were reprocessed and archived in December 2007. There is a problem with channel 673. Numerous drop outs occur throughout the period covered by this DQR.

Subject:	FKB/SKYRAD/M1 - IRT bias
DataStreams:	fkbskyrad60sM1.b1
Description:	On several days (especially in April, September, and December), the sky temperature measurement from the IRT exhibited a positive bias from the AERI measurement from about 20:00 to 07:00. This diurnal variation is highly correlated with the measurement of relative humidity so was most-likely due to the contribution of the temperature of water vapor, fog, and/or condensation on the lens and/or mirror.

Subject:	FKB/MFRSR/M1 - Heater not functioning
DataStreams:	fkbmfrsrM1.00, fkbmfrsrM1.a0, fkbmfrsrM1.b1
Description:	Flagging as suspect since the heater isn't working. Head should be at 40 deg C but heater was not functioning due to a bad connection. Maintenance resolved the issue.

Subject:	FKB/SONDE/M1 - RH values may be slightly overcorrected.
DataStreams:	fkbsondewnpnM1.b1
Description:	The desiccant in the GC25 ground check set began to lose efficiency at the beginning of this time period. Prior to 9/11/2007 the radiosonde RH readings while in the GC25 (assumed RH=0%) were below 1%RH. The RH readings began to exceed 1%RH on 9/11/2007 and increased more or less exponentially to 2.3% RH by the end of 9/18/2007. The desiccant was changed on 9/19/2007 and the radiosonde RH values while in the GC25 again dropped within the acceptable limit (< 0.5%RH, in fact). Because the value obtained from the radiosonde while in the GC25 is subtracted from the subsequent RH values as part of the ground check procedure, it is likely that soundings done late in this period may be biased low by no more than 2%RH. The exact amount of the correction applied is included in the netCDF header of each file.

Subject:	FKB/VCEIL/M1 - Reprocess: Incorrect serial_number and sum_backscatter fields
DataStreams:	fkbvceil25kM1.b1
Description:	Attribute serial_number: In most cases, this field is not representative of the actual serial number of the instrument because the value did not change when an instrument changed locations or was replaced with a spare. Variable sum_backscatter: An out-of-range condition for the "sum of detected and normalized backscatter" was reported as 0 instead of missing (-9999). The valid range is 0 - 0.0999 /srad.
Measurements:	fkbvceil25kM1.b1: sum_backscatter
