Subject: | SGP/SIRS/E15 - NIP (short_direct_normal) failure |
DataStreams: | sgpsirsE15.b1, sgpsirs20sE15.a0
|
Description: | Short_direct_normal was spiking to large positive and negative values (+2000/-2000) with
extended periods of missing data. Repair of broken cable corrected the problem.
Data are not recoverable. Suggest using remaining components (global hemispheric and
global diffuse) to reconstruct direct normal data during this time period. See SIRS
instrument handbook for details on this process. |
Suggestions: | Reconstruct direct normal from global and diffuse. |
Measurements: | sgpsirs20sE15.a0: - Instantaneous direct normal shortwave irradiance, pyrheliometer thermopile
voltage(inst_direct_normal) more
