| Subject: | SGP/SIRS/E15 - Data missing |
| DataStreams: | sgpsirsE15.b1, sgpsirs20sE15.a0
|
| Description: | The Short Direct Normal (NIP) instrument had a broken wire in the connector causing data
to be missing or incorrect. |
| Suggestions: | The data can be approximated from the two other shortwave datastreams available using
the following relationship:
short_direct_normal = (down_short_hemisp - down_short_diffuse)/cos(zenith angle) |
| Measurements: | sgpsirs20sE15.a0: more
sgpsirsE15.b1: - short_direct_normal
- short_direct_normal_max
- short_direct_normal_min
- short_direct_normal_std
