| Subject: | SGP/QCRAD/E15 - Direct normal irradiance intermittently low |
| DataStreams: | sgpqcrad1longE15.s2, sgpqcrad1longE15.c1, sgpqcrad1longE15.c2, sgpqcrad1longE15.s1 |
| Description: | Direct normal irradiance measurements appear to be intermittently too low and possibly incorrect during this time period. The cause is not known. No instrument DQRs currently exist describing the problem. |
| Suggestions: | Use caution with direct normal irradiance. Consider calculating it from global and diffuse SW irradiances or using MFRSR data. |
