Subject: | NSA/GNDRAD/C1 - power outage affecting some GNDRAD sensors |
DataStreams: | nsagndrad20sC1.a0, nsagndrad60sC1.b1, nsagndradC1.00 |
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. |

Subject: | NSA/GNDRAD/C1 - Reprocessed: Incorrect calibration coefficient |
DataStreams: | nsagndrad20sC1.a0, nsagndrad60sC1.b1 |
Description: | Installed Gndrad PSP (upwelling shortwave hemispheric irradiance) had calibration coefficient RS applied when it should have used Rsc. ARM is using IR corrected coefficients Rsc@45 and CFc@45 for PSPs deployed at all facilities. PSP #32012F3 should use RSc@45=109.39 and not Rs@45=110.97. Reprocessed to correct upwelling shortwave hemispheric irradiance (US) by: US(new) = (US(old) / 110.97 ) * 109.39 Reprocessing completed March 2008. |
