R: Convert reflectance to radiance using linear function...

convRef2RadLinear {satellite} | R Documentation

## Convert reflectance to radiance using linear function coefficients

### Description

The function converts the reflectance (ref) back to radiance (rad) given that linear conversion coefficients for both radiance and reflectance are available.

### Usage

    convRef2RadLinear(band, refm, refa, radm, rada, szen)

### Arguments

`band` | raster::RasterStack or raster::RasterLayer containing reflectance.
`refm` | Multiplication coefficient for reflectance conversion.
`refa` | Addtition coefficient for reflectance conversion.
`radm` | Multiplication coefficient for radiance conversion.
`rada` | Addition coefficient for radiance conversion.
`szen` | Sun zenith angle.

### Details

The conversion functions are taken from USGS' Landsat 8 Data Users Handbook which is available online at https://www.usgs.gov/land-resources/nli/landsat/landsat-8-data-users-handbook.

### Value

`raster::Raster*` object with converted values.
