| Description: | DATA REPROCESSED and CORRECTED:
During installation of the new Campbell datalogger system and associated program, the NIP
(S/N 33551E6) was assigned an incorrect calibration coefficient. A coefficient of 116.01
W/m2/mV was applied when it should have been 124.378 W/m2/mV. The correct calibration
coefficient has now been applied.
The data were archived April 2017. Please retrieve the reprocessed data for use in your

--- ORIGINAL DQR DESCRIPTION ---
---------------------------------------------------
During our site visit comparison at Darwin we observed that the skyrad NIP was reading
about 50 w/m2 lower than the comparison cavity radfiometer and the replacement NIP on the
comparison stand. We found that the calibration coefficient for the NIP (responsivity at
45o)was put in as 8.64X10-6. The NIP was new and had not been calibrated at SGP. The
factory number was 8.04X10-6. We corrected the calibration coefficient and the instruments
agreed to better than 5 w/m2. |
