Section 6: SMERGE Surface D<strong>at</strong>a Meteorological Preprocessor<br />

<strong>Table</strong> 6-4 (continued)<br />

Sample SMERGE Control File Inputs<br />

(SMERGE.INP)<br />

<strong>The</strong> optional st<strong>at</strong>ion elev<strong>at</strong>ion is a default value used to calcul<strong>at</strong>e<br />

a st<strong>at</strong>ion pressure from altimeter or sea-level pressure if the<br />

st<strong>at</strong>ion presure is missing and the st<strong>at</strong>ion elev<strong>at</strong>ion is missing in<br />

the file. If XELEV is not assigned a value (i.e. XELEV does not<br />

appear in this control file), then no default elev<strong>at</strong>ion is available<br />

and st<strong>at</strong>ion pressure remains missing.<br />
