The stations' weather instruments include a rain gage, anemometer, humidity sensor, pyrgeometer (which measures broadband-IR flux), thermometer, and pyranometer (which measures radiation several micrometers in the IR).
Figure 2 shows the annual cycle of the mean downwelling thermal radiation measured by a pyrgeometer and overhead cloud fraction measured using a total sky imager.
