Subject: | NSA/GNDRAD/C1 - power outage affecting some GNDRAD sensors |
DataStreams: | nsagndradC1.00, nsagndrad60sC1.b1, nsagndrad20sC1.a0 |
Description: | During the power outage the upwelling global measurement from the PSP instrument shows a slight increase from -5 to +0 W/m2. This is due to removal of thermal offsets induced by the AC heater during the power outage. This heater is installed within the PSP ventilator - it is necessary for the NSA/C1 climate. The upwelling longwave PIR instrument is unaffected due to case and dome temperature corrections. The IRT is AC powered and was not operational during this time period. |
Suggestions: | Instrument characteristic - no workaround possible. |
