CPRAMMET (Modified PCRAMMET) Processor
----------------------------------------------------------------------

Purpose:
--------
	  Reads a mixing height file and a surface meteorological data
          file in either CD144, SAMSON, or HUSWO format and produces
          an 'extended' ISC data file that may be used in CALPUFF.

Background:
-----------

          CPRAMMET is a modification to PCRAMMET that augments its
          treatment of relative humidity and solar radiation when
          preparing an 'ISC' met data file of the type accepted by
          CALPUFF.

          1)  It uses the RADSOL subroutine in PCRAMMET to estimate
              solar radiation from time-of-day and cloud-cover when
              radiation data are missing from the input data.  RADSOL
              already performs this function when computing the
              Monin-Obukhov length.

          2)  It writes solar radiation and RH fields when using CD144
              surface data format files.  (This is not enabled in
              PCRAMMET.)

          None of the modifications require inputs that differ from
          PCRAMMET, so the PCRAMMET users instructions remain valid.

          CPRAMMET Example With CD144 Met Data

          This example application of CPRAMMET illustrates the use of
          this processor when using hourly meteorological observations
          that are reported in CD144 format.  Options selected configure
          the output file for a full (wet & dry) deposition run, and
          therefore create an ISC-type file with an extended record
          structure that is acceptible to CALPUFF as an ISCMET.DAT file.
