| Subject: | SGP/QCRAD/E10 - Reprocess: Wrong calibration factor applied to NIP |
| DataStreams: | sgpqcrad1longE10.s2 |
| Description: | From about 950721 to about 970204 (19:12 GMT) the wrong calibration factor was applied to the NIP at site E10. The calibration factor that was used was 1.00E-06 Volts/(W m^2). The correct calibration factor is 8.338E-06 Volts/(W m^2). Thus the calibrated NIP values found in the netCDF files are too large by a factor of 8.338. Documented in instrument DQR D970213.1 |

| Subject: | SGP/QCRAD/E9 - Direct normal incorrect |
| DataStreams: | sgpqcrad1longE9.c2, sgpqcrad1longE9.s2 |
| Description: | Direct normal irradiance measurements appear to be incorrect. The cause of the problem is not known. No instrument DQR is available describing the problem at this time. Direct normal irradiance should not be used. It can be calculated from diffuse and global measurements or the MFRSR data can be substituted. |
