Dataset of Sentinel-1 surface soil moisture time series at 1 km resolution over Southern Italy

Description

The dataset consists of a time series of the Sentinel-1 (S-1) surface soil moisture (SSM) product at 1 km spatial resolution validated in Balenzano et al. (2021 a) over the Southern Italy. The specifications of the S-1 SSM product are provided in Balenzano et al. (2021 b). The SSM time series was obtained in correspondence of the ascending (RON A146) S-1 Interferometric Wide swath (IW) acquisition dates from January 2015 to December 2018 with a temporal gap between consecutive of 6 days (when both S-1A and S-1B data are available) or 12 days. On each date (183 in total), two co-registered layers are provided: mean SSM [m3/m3] and its standard deviation [m3/m3], which provides the SSM uncertainty. The retrieval algorithm is a time series short term change detection (STCD) that is implemented in the “Soil MOisture retrieval from multi-temporal SAR data” (SMOSAR) code (Balenzano et al. 2013).

Notes

This research was supported by the Scientific Exploitation of Operational Missions (SEOM) program of the European Space Agency, through the project "Exploitation of S-1 for Surface Soil Moisture Retrieval at High Resolution (Exploit-S-1)" (contract 4000118762/16/I-NB).
