Subject: | SGP/SIRS/C1 - NIP sensor failure |
DataStreams: | sgpsirs20sC1.a0, sgpsirsC1.b1 |
Description: | The short_direct_normal data are missing due to an instrument failure (NIP pyhrheliometer) likely due to a nearby lightning strike near the time of initial failure. The short_direct_normal data are not recoverable during this time period. However, direct normal data can be reconstructed from the down_short_diffuse_hemisp and down_short_hemisp using the following relationship for each data point: short_direct_normal = (down_short_hemisp - down_short_diffuse_hemisp)/cos(zenith angle) |
