PVC/IRT/M1 - Reprocess: Incorrect Configuration
DataStreams:pvcirt200msM1.a1, pvcirtM1.b1
Description:
The SKYRAD IRT was installed temporarily (waiting for the new enclosure) in a vertical 
orientation, without the use of the gold mirror. When irt_comm was started, the emissivity 
parameter in the startup file was not changed to 1.000 compensate for the absence of the 
mirror, resulting in a positive bias of about 5 K.

These data may be corrected by adjusting the radiance values for the difference in 
emmissivity.

PVC/IRT/M1 - Instrument failure
DataStreams:pvcirt200msM1.a1, pvcirtM1.b1
Description:
The IRT failed because of water intrusion. It was replaced with a unit installed inside a 
ventilated enclosure.
