SM2RAIN-ASCAT (2007-2019): global daily satellite rainfall from ASCAT soil moisture

SM2RAIN-ASCAT is a new global scale rainfall product obtained from ASCAT satellite soil moisture data through the SM2RAIN algorithm (Brocca et al., 2014). The SM2RAIN-ASCAT rainfall dataset (in mm/day) is provided over an irregular grid at 12.5 km on a global scale. The product represents the accumulated rainfall between the 00:00 and the 23:59 UTC of the indicated day. The SM2RAIN method was applied to the ASCAT soil moisture product (Wagner et al., 2013) for the period from January 2007 to 31 December 2019 (13 years), for version 1.2. The rainfall dataset is provided in netCDF format. A total of 13 netCDF files, one per year, are provided. The quality flag provided with the dataset has been used to mask out low quality data, as well as the areas characterised by complex topographic, frozen soil, and presence of tropical forests. A GeoTIFF version of the dataset is available here (to be updated): https://zenodo.org/record/3520620 A sample dataset that can be used for testing SM2RAIN algorithm is available here: https://zenodo.org/record/2580285 Details on the dataset development and its assessment with ground and reanalysis observations are provided as: Brocca, L., Filippucci, P., Hahn, S., Ciabatta, L., Massari, C., Camici, S., Schüller, L., Bojkov, B., Wagner, W.

With respect to version 1.1 we have changed SM2RAIN_ASCAT_0125_2019_v1.1.nc with SM2RAIN_ASCAT_0125_2019_v1.2.nc Other files (2007-2018) unchanged Fixed three errors wrt version 1.0: 1) missing data (2013-2018) in one small region in Mexico 2) missing data on 31-dec-2017 and 1-jan-2018 3) updated snow probability fla
