Estimate Soil Temperature RegimeSource:
Estimate soil temperature regime (STR) based on mean annual soil temperature (MAST), mean summer temperature (MSST), mean winter soil temperature (MWST), presence of O horizons, saturated conditions, and presence of permafrost. Several assumptions are made when O horizon or saturation are undefined.
vector of mean annual soil temperature (deg C)
vector of mean summer soil temperature (deg C)
vector of mean winter soil temperature (deg C)
logical vector of O horizon presence / absence
logical vector of seasonal saturation
logical vector of permafrost presence / absence
