1.0  DATA SET OVERVIEW
     

This data set contains 30-minute resolution energy balance bowen ratio
data from the Atmospheric Boundary Layer Experiments (ABLE) operated
by the Argonne National Laboratory in the Walnut River Watershed in
Butler County Kansas (east of Wichita).  The ABLE EBBR was located at
the Whitewater, KS site during the BAMEX period.  Data cover the
period from 20 May to 7 July 2003. The data are in columnar ASCII
format.

3.0  DATA COLLECTION AND PROCESSING


UCAR/JOSS conducted no processing or quality control on these data.


4.0  DATA FORMAT AND FILE NAMING


4.1  Data Format

These data are in columnar ASCII  format.

Sensors associated with new Whitewater EBBR installed May 1999.

Note that only the "30 minute" data (see below) are archived in the ABLE
ASCII archive area at this time.  Raw data files are however available
for parsing out the 5 or 15 minute data if desired.
