Subject: | TWP/SKYRAD/C3 - Incorrect NIP cal coefficient |
DataStreams: | twpskyrad60sC3.b1 |
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. |
Suggestions: | null data for dates between 24 May 2004 and 2 Sept 2004 at Darwin by 1.072 |
