Spatio-temporal variogram models for global and local daily air temperatures
Description
Variograms of residuals from multiple linear regression of mean, minimum, maximum daily temperatures on geometric temperature trend (GTT), MODIS LST, digital elevation model (DEM) and topographic wetness index (TWI). The models is computed from GSOD, ECA&D, GHCN-Daily or local meteorological stations. The obtained global or local models for mean, minimum, and maximum temperature can be used to produce gridded images of daily temperatures at high spatial and temporal resolution.
Usage

Format
A list of 9 space-time sum-metric models for daily air temperatures, units: space km, time days.
