wradlib.georef.misc.GeorefMiscMethods.bin_distance#
- GeorefMiscMethods.bin_distance(**kwargs)[source]#
Calculates great circle distance from radar site to radar bin over spherical earth, taking the refractivity of the atmosphere into account.
\[s = k_e r_e \arctan\left( \frac{r \cos\theta}{r \cos\theta + k_e r_e + h}\right)\]where \(h\) would be the radar site altitude amsl.
