Calculation of the Surface Temperature (Ts) from Geospatial Raster Data.

Ts Package

The Ts package provides tools to calculate the Surface Temperature (Ts) from raster data.
It uses albedo, NDVI, and air temperature (Ta) to generate the Ts raster.

Units

• The input air temperature raster (Ta) must be in Kelvin (K).
• The resulting surface temperature raster (Ts) will be in the same unit as Ta.

Raster requirements

• Input rasters (albedo, ndvi, Ta) do not need to have the same CRS or extent, the function will:

  • Align the CRS of all rasters to that of albedo.
  • Resample ndvi and Ta to the resolution of albedo.
  • Crop all rasters to the intersection of their extents.

• For meaningful results, input rasters should ideally cover roughly the same area.

Installation

You can install the development version of Ts directly from your local folder:

# Install from local directory
devtools::install("path/to/Ts")
