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.
Measurements:fkbskyrad60sM1.b1:
  • IR Brightness Temperature(sky_ir_temp)
  • sky_ir_temp_min
  • sky_ir_temp_max

FKB/GNDRAD/M1 - Reprocessed: Incorrect calibrations
DataStreams:fkbgndrad20sM1.a0, fkbgndrad60sM1.b1
Description:
An incorrect calibration coefficient was applied to the up_short_hemispheric instrument 
(PSP) for the specified time period.  Changes in the ARM PSP calibration procedure now 
generates two different calibration coefficients for the same instrument, Cf(non "IR 
corrected")and Cfc("IR corrected").  CFc should have been applied to this instrument but CF was 
erroneously used.

The affected PSP is S/N 34292F3 Cf=117.61 (incorrect applied), Cfc(correct)=116.07W/m2/mV

These data were reprocessed and archived in March 2008.

FKB/AOS/M1 - Data processing problem
DataStreams:fkbaosM1.a1, fkbnoaaaosM1.b1, fkbnoaaaosavgM1.b1
Description:
The AOS data was reprocessed for the AMF, SGP and NSA sites. There was an error in the 
processing of the corrections for the PSAP absorption signal such that a low pass filter was 
implemented for the scattering data used in these corrections.The difference between the 
corrected and previous data is < 0.05 Mm-1 (below the instrument detection limit) and 
should not have a significant effect on the previous data. Data will be reprocessed at a 
later time when more significant changes to the data processing are implemented.
