| Subject: | SGP/SIRS/E7 - Downwelling shortwave data dropouts |
| DataStreams: | sgpsirsE7.b1, sgpsirs20sE7.a0
|
| Description: | The down_short_hemisp data was dropping out to negative numbers and had high negative
offsets. PM techs reseated the cable connections and found the ventilator fan had failed. |
| Suggestions: | Disregard the down_short_hemisp data during this time |
| Measurements: | sgpsirs20sE7.a0: - Instantaneous Downwelling Hemispheric Shortwave, Pyranometer Thermopile Voltage(inst_global)
