Subject: | SGP/SIRS/E13 - Adjust Direct Normal Irradiance |
DataStreams: | sgpsirsE13.01, sgpsirsE13.00, sgp1swfanalsirs1longE13.c1, sgp15swfanalsirs1longE13.c1 |
Description: | Direct normal broadband shortwave irradiance measured by NIP s/n 30585E6 was found to have a 1.76% 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 30585E6 on July 18, 2000 was -2.2% to +2.8%. Data from NIP s/n 30585E6 can be adjusted according to the in-situ comparisons to reduce the apparent measurement bias. |
Suggestions: | Multiply all direct normal irradiance measurements by 1.0176. |
