Estimate Soil Temperature Regime

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.

Usage

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.
