Description
Cloud vertical properties (e.g., cloud top/base height) are critical to the estimation of atmospheric radiation. For understanding the linkage between model biases on cloud vertical properties and model biases on estimated atmospheric radiation, we use available reanalyses (e.g., ERA-Interim, NCEP/NCAR Reanalysis I, NCEP/DOE Reanalysis II, MERRA, and NARR) to first investigate the model biases on the cloud properties and estimated atmospheric radiation, by using the observations from the U. S. Atmospheric Radiation Measurement (ARM) Climate Research Facility Southern Great Plains (SGP) site. After that, the relationships between the model biases are examined. Connections to the common meteorological variables (e.g., temperature and relative humidity) are also discussed.
