| Subject: | SGP/QCRAD/C1 - SW direct normal data drop out |
| DataStreams: | sgpqcrad1longC1.c2, sgpqcrad1longC1.s2, sgpqcrad1longC1.s1, sgpqcrad1longC1.c1 |
| Description: | NIP cable had failed during this time period. Short_direct_normal data are not recoverable during this time period. However, it can be reconstructed using the following formula for each one minute data: short_direct_normal = (down_short_hemisp-down_short_diffuse_hemisp)/cos(zenith angle) Documented in instrument DQR D090623.1 |
| Suggestions: | Use direct normal measurements from E13 or calculate from diffuse and global. |
