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.

estimateSTR(
  mast,
  mean.summer,
  mean.winter,
  O.hz = NA,
  saturated = NA,
  permafrost = FALSE
)

Arguments

mast

vector of mean annual soil temperature (deg C)

mean.summer

vector of mean summer soil temperature (deg C)

mean.winter

vector of mean winter soil temperature (deg C)

O.hz

logical vector of O horizon presence / absence

saturated

logical vector of seasonal saturation

permafrost

logical vector of permafrost presence / absence

Value

Vector of soil temperature regimes.
