Toolbox for Reducing Atmospheric InSAR Noise. One of the main challenges in InSAR processing is related to atmospheric delays, especially tropospheric delays. Different correction methods are applied today based on auxiliary data, including GNSS, weather models (e.g. ECMWF ERA-I, WRF, NARR, etc), spectrometer data (MERIS and MODIS), or combinations of different sources. Alternative methods exist to estimate the tropospheric delays from the radar data themselves.
