Raytracing Atmospheric Delay Estimation for RADAR - RAiDER(NPO-51433-1)

RAiDER is a Python package that contains tools to calculate tropospheric radar slant delays for both airborne and space borne sensors. It estimates delays by calculating the index of refractivity at the native weather model grid nodes and then integrating along the ray path of the signal, from the ground pixel to the sensor location (up to a reference height).
