Subject: | SGP/QCRAD/C1 - NIP failure |
DataStreams: | sgpqcrad1longC1.c2, sgpqcrad1longC1.s2, sgpqcrad1longC1.s1, sgpqcrad1longC1.c1 |
Description: | The short_direct_normal (NIP instrument) cable failed during this time period. Data are not recoverable. Users can derive an estimate of direct normal values using the following formula: short_direct_normal = (down_short_hemisp - down_short_diffuse_hemisp)/cos(zenith angle) Documented in instrument DQR D110628.2 |
Suggestions: | Use direct normal from E13, MFRSR, or calculate it from SW global and diffuse as described. |
