| Description: | DATA REPROCESSED and CORRECTED:
Incorrect calibration coefficients were input into the Manus skyrad logger for the 4 day
period listed. This affected the PSP_Diffuse and PSP_Global values for this instrument.
The data in the b1 datastream was corrected by multiplying the data by a ratio of the
correct to incorrect calibration factors. Please retrieve the reprocessed data for use in
your analysis.
You may find these data using the ARM Discovery tool at the following link:

--- ORIGINAL DQR DESCRIPTION ---
---------------------------------------------------
The following incorrect calibrations values were input into SKYRAD and GNDRAD loggers:
Values in Logger Correct Values
Responsivity Cal Number Responsivity Cal number
PSPD_SKYRAD 8.31 120337 8.32 120192
PSPG_SKYRAD 8.46 118203 8.64 115741
PSPDn_GNDRAD 7.79 128370 7.90 126582
This error occurred because several calibration coefficients are reported and the wrong
one was used. The 45-55 degree (solar zenith angle range) value should be used. At
approximately 02 GMT on 19990304, the calibrations were corrected.
Data will be reprocessed (RID-52). |
