Simulating the correction
sim_correct.Rdsim_correct() Converts the brightness temperature to land surface temperature of a single value, vector or matrix or SpatRaster object.
It is basically Equation 3 from vignette("Background") in the form of an R-function.
This function is intended to simulate the effects of the parameters on the output and doesn't process any positional information/metadata.
Usage
sim_correct(
T_bright,
flight_height = 50,
T_air = 25,
rel_hum = 70,
T_bg = NA,
emiss = 0.985
)Arguments
- T_bright
Brightness temperature (in Kelvin) that you want to convert. This can either be a single value, a vector or a matrix or
SpatRasterobject- flight_height
(numerical) the height between the camera and the OBJECT OF INTEREST. Default is 50 m
- T_air
(numerical) the air temperature in deg C during the flight. Default is 25 deg C
- rel_hum
(numerical) the relative humidity in % during the flight. Default is 70 %
- T_bg
(numerical) the background temperature in Kelvin, temperature measured from the aluminium panel. If not recorded set to NA and the parameter will not be accounted for.
- emiss
(numerical) the emissivity, here by default an average for plants is given (0.985)
