About this data
<p style="text-align: justify;">This dataset provides indicators on total precipitation and the number of extreme precipitation days, in large (TL2) and small (TL3) regions.</p> <p><strong>Data definition and source</strong></p> <p>Precipitation is the sum of all liquid and frozen water - such as rain and snow - that reaches the Earth's surface each year. It excludes fog, dew and any precipitation that evaporates before reaching the ground. Extreme precipitation days are defined as days with more than 20 mm of total precipitation. Changes in precipitation and extreme precipitation days are referenced to the 1981-2010 baseline average. The estimates rely on the <a href="https://developers.google.com/earth-engine/datasets/catalog/ECMWF_ERA5_LAND_DAILY_AGGR">ERA5-Land reanalysis</a> dataset.</p> <p style="text-align: justify;">ERA5-Land is used as it provides harmonised, globally consistent coverage at fine spatial resolution (0.1 degree), enabling the production of comparable subnational indicators also where national meteorological data are not available at the required scale. </p> <p style="text-align: justify;">These estimates may differ from official subnational climate statistics due to differences in methodological approaches, such as the use of reanalysis based top down modelling versus in situ observations, along with variations in input data sources, spatial resolution, and the models and algorithms used to generate temperature estimates.</p> <p><strong>Definition of regions</strong></p> <p style="text-align: justify;">Regions are subnational units below national boundaries. OECD countries have two regional levels: large regions (territorial level 2 or TL2) and small regions (territorial level 3 or TL3).
