The Shortwave (SW) Clear-Sky Detection and Fitting Algorithm: Algorithm Operational Details and Explanations

PDF Version Also Available for Download.

Description

This document describes some specifics of the algorithm for detecting clear skies and fitting clear-sky shortwave (SW) functions described in Long and Ackerman (2000). This algorithm forms the basis of the ARM SW FLUX ANAL 1Long VAP. In the Atmospheric Radiation Measurement (ARM) case, the value added procedures (VAP) can be described as having three parts: a “front end,” a “black box,” and a “back end.” The “front end” handles the file management of the processing, what range of data files to process in the run, which configuration file to use for each site, extracting the data from the ARM ... continued below

Description

This document describes some specifics of the algorithm for detecting clear skies and fitting clear-sky shortwave (SW) functions described in Long and Ackerman (2000). This algorithm forms the basis of the ARM SW FLUX ANAL 1Long VAP. In the Atmospheric Radiation Measurement (ARM) case, the value added procedures (VAP) can be described as having three parts: a “front end,” a “black box,” and a “back end.” The “front end” handles the file management of the processing, what range of data files to process in the run, which configuration file to use for each site, extracting the data from the ARM NetCDF files into an ASCII format for the code to process, etc. The “back end” produces ARM-format NetCDF files of the output and other file management. The “black box” is the processing code(s), and is what is discussed in this document. Details on the “front” and “back” ends of the ARM VAP are presented elsewhere.
