Abstract
Abstract. We introduce the Frequent Rainfall Observations on GridS (FROGS) database
(Roca et al., 2019). It is composed of gridded daily-precipitation products
on a common 1∘×1∘ grid to ease intercomparison and
assessment exercises. The database includes satellite, ground-based and
reanalysis products. As most of the satellite products rely on rain gauges
for calibration, unadjusted versions of satellite products are also provided
where available. Each product is provided over its length of record and up
to 2017 if available. Quasi-global, quasi-global land-only, ocean-only and tropical-only as well as regional products (over continental Africa and
South America) are included. All products are provided on a common netCDF
format that is compliant with Climate and Forecast (CF) Convention and Attribute Convention for Dataset Discovery (ACDD) standards. Preliminary
investigations of this large ensemble indicate that while many features
appear robust across the products, the characterization of precipitation
extremes exhibits a large spread calling for careful selection of the
products used for scientific applications. All datasets are freely available
via an FTP server and identified thanks to the DOI:
