SPHERA High Resolution Reanalysis over Italy - Hourly accumulated total precipitation

Please refer to the latest-released version (v2) of this dataset: https://zenodo.org/records/14617083 SPHERA (High Resolution REAnalysis over Italy) is a convection-permitting regional reanalysis developed by ARPAE-Emilia Romagna and publicly available. The SPHERA domain covers Italy and the surrounding seas with a horizontal resolution of 2.2km. The temporal coverage corresponds to the period 1995-2020 and the dataset is available at a hourly frequency. SPHERA reanalysis was developed using the Numerical Weather Prediction model COSMO (www.cosmo-model.org) nested in the global reanalysis ERA5 produced by ECMWF. Moreover, upper-air and surface observations were assimilated at the convection-permitting scale by the COSMO nudging scheme. This record reports the hourly accumulated total precipitation for the period 1995-2020. Other fields currently available on Zenodo are the surface relative humidity at 2-meter height (over three different records due to space constraints): 1995-2003: https://zenodo.org/uploads/12724026 2004-2012: https://zenodo.org/uploads/12724104 2013-2020: https://zenodo.org/uploads/12724140 and the hourly surface air temperature at 2-meter height: 1995-2003: https://zenodo.org/records/12567563 2004-2012: https://zenodo.org/records/12582246 2013-2020: https://zenodo.org/records/12582797 Details on the SPHERA dataset production, as well as data verification against surface observations are reported in peer-reviewed publications.
