| Subject: | TWP/QCRAD/C3 - NIP instrument failure |
| DataStreams: | twpqcrad1longC3.s1, twpqcrad1longC3.c1, twpqcrad1longC3.s2, twpqcrad1longC3.c2 |
| Description: | NIP is not working during these time periods as described in instrument DQRs D061214.1 & D081222.2. Direct normal irradiance is bad. |
| Suggestions: | Do not use direct normal irradiance during these times. The direct flux can be used from the MFRSR or it can be calculated from the total and diffuse downwelling fluxes. |
