lwdr: Longwave downward radiation

In environmentalinformatics-marburg/reset: Remote Sensing-Based Evapotranspiration

Description

Longwave downward radiation model proposed by Allen et al. (2007) and Hwang et al. (2013; currently not implemented).

Usage

lwdr(ea, ta, ...)

Arguments

ea	Raster* object, effective atmospheric emissivity, e.g. derived from atmosphericEmissivity.
ta	Raster* object, air (or land surface) temperature.
...	Further arguments passed on to overlay.
