Improvements in AVHRR Daytime Cloud Detection Over the ARM NSA Site
Clouds play an important role in the radiation budget over Arctic and Antarctic. Because of limited surface observing capabilities, it is necessary to detect clouds over large areas using satellite imagery. At low and mid-latitudes, satellite-observed visible (VIS; 0.65 µm) and infrared (IR; 11µm) r...

Summary: | Clouds play an important role in the radiation budget over Arctic and Antarctic. Because of limited surface observing capabilities, it is necessary to detect clouds over large areas using satellite imagery. At low and mid-latitudes, satellite-observed visible (VIS; 0.65 µm) and infrared (IR; 11µm) radiance data are used to derive cloud fraction, temperature, and optical depth. However, the extreme variability in the |
