SGP - Best Estimate Flux VAP files

The Best Estimate Flux VAP uses input from the 3 radiometer platforms located
at the SGP Central Facility to determine the best estimate of the various
broadband irradiance measurements. Prior to the installation and operation of
the 3rd set of radiometers at the SGP CF, a data set spanning 19950519 -
19970321 has been produced manually, and made available to the ARM community
via the ARM Archive. The purpose of this DQR is to notify users of the above
date range that covers the period the Best Estimate was manually produced, and
to point users to the ARM Technical Report Web page at
http://www.arm.gov/docs/documents/tech_reports/index.html for documentation on
the 'manual' methodology used, i.e. the documentation. Users should refer to
the ARM Technical Report titled 'The ARM Southern Great Plains Central Facility
Best Estimate Radiative Flux CD Presented at the April, 2002 ARM Science 
Team Meeting St. Petersburg, FL'
