5.9 - Detailed Penman-Monteith Output File (*.opm)
The detailed Penman-Monteith output file (*.opm) is generated when a Penman-Monteith or ASCE
Standardized Penman-Monteith analyses is selected by setting flag1= 3 or 5, respectively, in
the model control file (see Section 4.4). This option provides detailed results of the Penman-Monteith
or ASCE Standardized Penman-Monteith consumptive use calculation during the growing season for all crop
types associated with each structure by day, including the following:
- reference evapotranspiration,
- Penman-Monteith crop coefficients \(K_c\),
- potential consumptive use,
- effective rainfall, and
- irrigation water requirement.
An example is provided in Appendix A.
