GIST ARM-CART Upper Air Sounding Datasets 
     
     
     1.0  General Description
          
          This is one of the upper air sounding datasets developed for the
     GEWEX Continental scale International Project (GCIP) Integrated System
     Test (GIST) conducted from 01 April to 31 August 1994. Included in this
     dataset are four Atmospheric Radiation Measurement - Clouds And
     Radiation Testbed (ARM-CART) sounding stations; Central Facility OK,
     Hillsboro KS, Morris OK and Vici OK. The area covered by the GIST 
     experiment extends from approximately 91W to 107W longitude and 31N
     to 40N latitude.
          
     2.0  Detailed Data Description
          
     2.1  Data Remarks
          
          ARM-CART files from April 8, 1994 through May 20, 1994 were
     delivered as two separate files, one wind file and one thermodynamic file.
     These files were merged by OFPS to create a final sounding for each pair
     of files.
     
          ARM-CART soundings were not available for the following days: 
     940401 through 940407, 940605, 940612, 940619, 940626, 940703,
     940710, 940717.
          
     3.0  Quality Control Processing
          
          ARM-CART soundings were Quality Controlled (Lesht 1995) and
     provided to UCAR/OFPS by the ARM-CART Project. This dataset
     underwent an OFPS QC process which consisted of internal consistency
     checks. This included "reasonable" limit checks on all parameters and
     rate-of-change checks on temperature, pressure and ascension rate. OFPS
     did not perform visual quality control procedures on this data.
