SAR-derived water vapor maps for meteorological applications: processing advancement.

Numerical Weather Prediction Models (NWPM) can significantly benefit from the ingestion of SAR-derived products like water vapor maps. In particular, the contribution of SAR data to NWPM forecasts can be very effective if two conditions are satisfied: the estimated water vapor maps must be ‘dense’ and they must cover wide areas. Water vapor maps are […]

Water vapor maps from the integration of GNSS measurements, SAR satellite images and NWP models

Copernicus Sentinel-1 SAR (Synthetic Aperture Radar) acquisitions allow for the generation of high resolution maps containing the variation of atmospheric water vapor content with respect to a reference situation (MASTER). The maps are in fact the product of a processing technique, known as SAR Interferometry (InSAR), which involves the combination of satellite SAR images acquired […]
