Files having data for Penman-Monteith (?.wpm? as a suffix):
?
number of spatial identifiers describing the specified sub-area.
?
number of unique weather stations in the specified sub-area (the union of the spatial identifiers) with
data on one or more of the following: daily temperature, daily precipitation, daily vapor pressure,
daily wind speed, daily solar radiation
?
begin year (i.e. 1990)
?
end year (i.e. 1992)
?
precipitation weights per year per spatial identifier DEFAULT (crdss-cu recommended weights per
county-huc)
?
non-precipitation weights per year per spatial identifier DEFAULT (crdss-cu recommended weights
per county-huc)
Data describing the CRDSS-CU recommended weather station(s) in the county-huc that covers the
specified sub-area:
?
weather station name (string)
?
latitude and longitude (dec degs)
?
elevation (ft)
?
Zh (height of wind speed measurement) (ft)
?
Zm (height of humidity/temp measurement) (ft)
Data required from each weather station:
?
28 deg spring frost month, day per year
?
28 deg fall frost month, day per year
?
32 deg spring frost month, day per year
?
32 deg fall frost month, day per year
?
maximum temperature per day (deg F)
?
minimum temperature per day (deg F)
?
dewpoint temperature per day (deg F)
Note: The dewpoint is computed from vapor pressure.
?
solar radiation per day (lang)
?
wind speed per day (mi/hr)
? ?
precipitation per day (in)
5.0 ?cucropco? DMI - Returns CU Model Input File For Crop Coefficients
This DMI generates two formatted crop coefficient files required by the irrigation component of the CU
model. The files generated are formatted based on the methods used in the CU model. Files having
?.kbc? as a suffix, contain data formatted for Blaney-Criddle. Files having ?.kpm? as a suffix, contain
data formatted for Penman-Monteith. The general function of this DMI is to return formatted data for
each crop type within the specified sub-area.
