Summary
SM2RAIN-ASCAT is a global daily rainfall dataset with spatial sampling of 12.5 km available from 2007 to August 2019
Description Data set
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 cumulated 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 August 2019 (13 years).
The rainfall dataset is provided in netCDF format. A total of 12 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.
Details on the dataset development and its assessment with ground and reanalysis observations are provided as:
