NAmerica:4km:1980-:D:Download daily data from METDATA based on PRISM.

This archive contains daily surface meteorological (METDATA) data for the Continental United States at 4-km (1/24-deg) resolution. The meteorological variables are maximum/minimum temperature, precipitation amount and duration, maximum/minimum relative humidity,downward shortwave solar radiation, wind speed and direction, and specific humidity. The method utilized here combines desirable spatial attributes of gridded climate data from PRISM and desirable temporal attributes of regional-scale reanalysis and daily gauge-based precipitation from NLDAS-2 to derive a spatially and temporally complete high resolution gridded dataset of surface meteorological variables for the continental US for 1979-present. Validation of this data suggests that it can serve as a suitable surrogate for landscape-scale ecological modeling across vast unmonitored areas of the US.

Whenever you publish research based on data from this archive, please reference this data by using the phrase “daily gridded meteorological data (METDATA) for the continental US” and by citing the article (Abatzoglou,2012). Further, appropriately acknowledge the National Science Foundation (NSF), Idaho EPSCoR and the individual investigators responsible for the data set.

Parameters:

• lat – The latitude of the point. North hemisphere is positive from 0 to 90. South hemisphere is negative from 0 to -90.

• lon – The longitude of the point. Western hemisphere (west of Greenwich Prime Meridian) is negative 0 to -180. The eastern hemisphere (east of the Greenwich Prime Meridian) is positive 0 to 180.

• variables (str) –

  At the command line can supply a comma separated list of variable names. Using the Python API needs to be a Python list of strings.

  The current list of available METDATA variables are in the following table and you can use either the “Short” or “Long” names.
