The active remotely-sensed clouds locations (ARSCL) value-added product (VAP) combines data from active remote sensors to produce an objective determination of cloud location, radar reflectivity, vertical velocity and Doppler spectral width. Information about the liquid water path in these clouds and the frequency of precipitation is available from the Microwave Water Radiometer (mwrlos) and the Surface Meteorological instruments (SMET or SMOS). To facilitate comparison of these fields with output from cloud resolving models and for other data analysis activities, a VAP has been created that performs statistical analysis of these data. Frequency distributions are computed and written in an output file in a manner that facilitates user flexibility. The structure enables users to quickly compute statistics for multiples of the half-hour and daily analysis periods that are the baseline for the statistical computations. Output for the 6-hour and daily periods is also provided in graphical format, which allows quick, cursory analysis of the statistical characteristics of the cloud data.
