Sentinel-1 interferograms and weather-based tropospheric delays maps (ERA5, GACOS) for two volcanoes: Piton de la Fournaise and Merapi

InSAR Sentinel-1 dataset and weather-based models used in the paper "Benefits of GNSS local observations compared to global weather-based models for InSAR tropospheric corrections over tropical volcanoes: case studies of Piton de la Fournaise and Merapi" by Albino et al. (2024).

The two zip files are associated with the two targets: REUNION_ISLAND and MERAPI. The directories "ERA5" and "GACOS" contain the GACOS and ERA5 tropospheric delay maps per epoch in geotiff format, respectively. The directory "INTERFEROGRAM" contains the unwrapped interferograms in geotiff format. The "AUX" directory contains the DEM and incidence angle in geotiff format.
