The mket program takes a year (or years) specified on the command line and writes the ET package to the screen. The output can be redirected to a file.
The station locations are shown in the following table.
| Station | Longitude | Latitude | Easting | Northing | Row | Column |
|---|---|---|---|---|---|---|
| Akron | -103:09 | 40:09 | 480549 | 14607776 | 68 | 41 |
| McCook | -100:35 | 40:14 | 1198494 | 14614955 | 67 | 177 |
| Red Cloud | -98:17 | 40:05 | 1840882 | 14557195 | 68 | 299 |
The monthly maximum ET in inches for the month for each model column is obtained by linear interpolation based on the column number of the stations shown in the above table. Negative values are set equal to zero.
The area of phreatophytes in each cell is read from the file ../data0/etarea.dat. This file contains the number of acres of phreatophytes in the cell.
The maximum ET rate in inches over the cell is calculated as the interpolated rate for the column times the phreatophyte acres divided by 640 acres per cell. This cell by cell rate in inches for the month over the cell is written to the ET package input file. The U2DREL multiplier is set to convert inches for the month to feet per second as required by MODFLOW-2000.
The ET ground surface is included by reference to the file ../static/11.etsurf. The extinction depth is set at a constant 10 feet.
