Subject: | SGP/SIRS/C1 - Reprocess: Adjust Direct Normal Irradiance |
DataStreams: | sgpsirsC1.00, sgp1swfanalsirs1longC1.c1, sgp15swfanalsirs1longC1.c1, sgpsirsC1.01 |
Description: | Direct normal broadband shortwave irradiance measured by NIP s/n 30722E6 was found to have a 0.62%% negative bias when compared in-situ with absolute cavity radiometer measurements taken on August 21, 2000. The estimated measurement uncertainty of the calibration of NIP s/n 30722E6 on July 18, 2000 was -2.6% to +4.8%. Data from NIP s/n 30722E6 can be adjusted according to the in-situ comparisons to reduce the apparent measurement bias. |
Suggestions: | Multiply all direct normal irradiance measurements by 1.0062. |
