3.5.2 Specification of Anemometer Height
An important input for both the Short Term and the Long Term models is the specification of the anemometer height, i.e., the height above ground at which the wind speed data were collected. Since the models adjust the input wind speeds from the anemometer height to the release height (see Section 1.1.3 of Volume II), the accurate specification of anemometer height is important to obtaining the correct model results. The syntax and type of the ANEMHGHT keyword are summarized below:
ME ANEMHGHT Zref (Zrunit)
where the parameter Zref is the height of the anemometer measurement above ground, and the optional parameter Zrunit is used to specify the units of Zref. Valid inputs for Zrunit are the secondary keywords METERS or FEET. The default units for Zref are in meters if Zrunit is left blank.
3.5.3 Specifying Station Information
Two keywords are used to specify information about the meteorological stations, SURFDATA for the surface meteorological station, and UAIRDATA for the upper air station used in the determination of mixing heights. The syntax and type of these keywords are summarized below:
ME SURFDATA Stanum Year (Name) (Xcoord) (Ycoord)
ME UAIRDATA Stanum Year (Name) (Xcoord) (Ycoord)
where Stanum is the station number, e.g. the 5‑digit WBAN number for NWS stations, Year is the year of data being processed (either 2 or 4 digits), Name is an optional character field (up to 40 characters with no blanks) specifying the name of the station, and Xcoord and Ycoord are optional parameters for specifying the x and y coordinates for the location of the stations. At the present time, the station locations are not utilized in the models. Therefore, no units are specified for Xcoord and Ycoord at this time, although meters are suggested in order to be consistent with the source and receptor coordinates.
