2.4.5 Specifying the Meteorological Input ‑ ME Pathway

     The MEteorolgy pathway has the following three mandatory keywords (besides STARTING and FINISHED, of course):

INPUTFIL ‑     Specifies the filename and format for the input meteorological data file.

ANEMHGHT ‑     Specifies the anemometer height for the wind data to be used for the modeling run.

SURFDATA ‑     Specifies information about the surface meteorological data which will be used in the modeling.

UAIRDATA ‑     Specifies information about the upper air meteorological data (i.e. mixing heights) which will be used in the modeling.

For the purposes of this example we will assume that the meteorological data file is a formatted ASCII file in the default format for ISCST3 that was generated by the PCRAMMET meteorological preprocessor program.  The filename is PREPIT.ASC (the sample file that is provided on the SCRAM BBS with the ISCST3 model), and it consists of twenty days of data for Pittsburgh, PA from 1964.  The runstream images for the MEteorology pathway would look something like this:

ME STARTING

   INPUTFIL  PREPIT.ASC

   ANEMHGHT  20 FEET

   SURFDATA  94823  1964  PITTSBURGH

   UAIRDATA  94823  1964  PITTSBURGH

ME FINISHED

11

     The first parameter on the INPUTFIL keyword is the filename, which can be entered as a full DOS pathname, including the drive specification and subdirectories, up to a total of 40 characters.  The second parameter is the format of the meteorology data file.  In this case the secondary keyword is blank, indicating that the meteorological data file is an ASCII file in the default format for the model.  Another option would be to place the secondary keyword UNFORM following the filename, in which case the model will assume an unformatted meteorological data file of the type generated by PCRAMMET.  The  order of variables assumed for the ASCII file input is as follows:  year, month, day, hour, flow vector, wind speed (m/s), temperature (K), stability category, rural mixing height (m), and urban mixing height (m).  Other user options for specifying the format for ASCII meteorology files are described more fully in Section 3.5.1.
