Description: | Air temperature is bad or noisy during this time. Air temperature data is needed for tests on LW up and LW down pyrgeometer case and dome temperatures, and tests on the irradiances from upwelling LW/SW and downwelling LW. There were no instrument DQRs on this problem at the time this report was submitted. |
