HydroGFD3.0 (Hydrological Global Forcing Data): a 25 km global precipitation and temperature data set updated in near-real time

Abstract. HydroGFD3 (Hydrological Global Forcing Data) is a data set of bias-adjusted reanalysis for daily precipitation and minimum, mean, maximum temperature. It mainly intended large-scale hydrological modelling but also suitable other impact modelling. The has an almost global land area coverage, excluding the Antarctic continent small islands, at horizontal resolution 0.25?, i.e. about 25 km. available complete ERA5 time period, currently 1979 until 5 d ago. This period will be extended back to 1950 once catalogue available. historical adjusted using gridded observational sets, acquire real-time data, collection several reference sets used. Consistency in attempted by relying on background climatology only making use anomalies from different sets. Precipitation mean bias as well number wet days month. latter calibrated statistical method with input monthly anomaly such that no additional are necessary. temperature toward observations applied 1 h steps reanalysis. Daily then calculated. performance par similar products, although there significant differences parts globe, especially where uncertain. Further, tends have higher extremes, partly due its spatial resolution. In this paper, we present methodology, evaluation results, how access https://doi.org/10.5281/zenodo.3871707 (Berg et al., 2020).
