DAYMET
Daymet is a model that generates daily surfaces of temperature, precipitation, humidity, and radiation over large regions of complex terrain. Daymet was developed at the University of Montana, Numerical Terradynamic Simulation Group (NTSG), to fulfill the need for fine resolution, daily meteorological and climatological data necessary for plant growth model inputs

Input Parameters
Site code example: GEOM:POINT(-113 45)
Variable example: DAYMET:VariableCode
The function takes String representing a lat/lon point in decimal degrees at a single point and returns a time series of the Variable of interest. The Longitude and Latitude arguments should locate a point within the conterminous United States. The data are provided with a daily time step.
Data before 01/01/1980 or after 12/31/2003 may not be available.
Valid Variable codes range from 1 to 7. The codes represent the following Variables:
1 - Daily maximum temperature (deg C)
2 - Daily minimum temperature (deg C)
3 - Average temperature during day (deg C)
4 - Precipitation (cm)
5 - Vapor Pressure Deficit (Pa)
6 - Solar Radiation (SRAD) (W m -2)
7 - Day length (s)
