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.
