Atlas of Simultaneous Occurrence of Different Cloud Types Over Land

The atlas covers cloud observations over the land. The reader is referred to NCAR/TN-201+STR, the first atlas of the series for details of the procedures used in classification and grouping of cloud types, and the general methodology of determining different cloud type co-occurrences.

Additional discussion is contained in this atlas to describe those cases where a different procedure was followed either as an improvement, or to fit the different circumstances under which land-based cloud observations are made. The current cloud climatology study is part of the International Satellite Cloud Climatology Program (ISCCP) and will provide a complementary data set for evaluating and validating results from the First ISCCP Regional Experiment (FIRE) and subsequent field experiments.
