| Subject: | TWP/QCRAD/C2 - upwelling radiometers inverted |
| DataStreams: | twpqcrad1longC2.s2, twpqcrad1longC2.s1, twpqcrad1longC2.c1, twpqcrad1longC2.c2 |
| Description: | During calibration check periods the gndrad instruments are inverted to compare with the skyrad pir and psp. Most periods described in instrument DQRs: D990909.1, D030224.1, D031007.4, D040929.2, D050926.6 Last two periods identified manually from data. |
| Suggestions: | Do not use upwelling longwave or shortwave irradiance, they are measuring downwelling irradiance during these times. |
