PyAPS - Python based Atmospheric Phase Screen Estimation

PyAPS is a python module that estimates differential phase delay maps due to the stratified atmosphere for correcting radar interferograms. It is based on Delaypackage originally written by Romain Jolivet for estimating phase screens due to stratified atmosphere using ECMWF's ERA Interim reanalysis. The metholody and validation of DelayPackage can be found in

Jolivet, R., R. Grandin, C. Lasserre, M.-P. Doin and G. Peltzer (2011), Systematic InSAR tropospheric phase delay corrections from global meteorological reanalysis data, Geophys. Res. Lett., 38, L17311, doi:10.1029/2011GL048757

PyAPS includes support for ERA Interim, NARR and MERRA weather models. PyAPS uses the humidity, pressure and temperature information from meteorological models to estimate the dry and wet components of the atmospheric delay.
