                         February 29, 2020

This file describes the components included in this release of the AERSURFACE tool,
version 20060.  The AERSURFACE tool has been developed to aid AERMOD users in
obtaining reproducible surface characteristic values, including albedo, Bowen ratio,
and surface roughness length, for input to the AERMET meteorological processor.

The following lists the files associated with this release of AERSURFACE:
