DAYMET Web Service

DAYMET

Developmental service. This service is internal CUAHSI use, and evaluation.

Daymet is a model that generates daily surfaces of temperature, precipitation, humidity, and radiation over large regions of complex terrain. This web service provides methods for retrieving data from Daymet. For more information about Daymet, see the Daymet home page at http://www.daymet.org/

The following operations are supported. For a formal definition, please review the Service Description.

GetValues
This function returns a string formatted as XML containing DAYMET time series data. 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)
Test arguments: GetValues("GEOM:POINT(-113 45)", "DAYMET:4", 1980-01-01, 1981-01-01)

GetVariableInfo
Given a variable code, this method returns the variable's name. Pass in the variable in this format: 'NetworkName:Variable'

GetVariableInfoObject
Given a variable code, this method returns the variable's siteName. Pass in the variable in this format: 'NetworkName:Variable'
