Variable<br />

No.<br />

Variable Type Description<br />

1 IINDEX integer I-index (X direction) <strong>of</strong> the grid point in the<br />

extraction subdomain<br />

2 JINDEX integer J-index (Y direction) <strong>of</strong> the grid point in the<br />

extraction subdomain<br />

3 XLATDOT real array N. L<strong>at</strong>itude (degrees) <strong>of</strong> the grid point in the<br />

extraction subdomain (positive for the Northern<br />

Hemisphere, neg<strong>at</strong>ive for Southern Hemisphere)<br />

4 XLONGDOT real array E. Longitude (degrees) <strong>of</strong> the grid point in the<br />

extraction subdomain (N.B., the MM4/MM5<br />

convention is different than the CALMET<br />

convention: MM4/MM5 uses neg<strong>at</strong>ive values for<br />

Western Hemisphere and positive values for<br />

Eastern Hemisphere. CALMET internally<br />

converts the longitudes in the MM5.DAT file, so<br />

the MM4/MM5 convention must be used in the<br />

MM5.DAT file)<br />
