Extreme temperatures - Local areas

<p>This dataset provides extreme temperature trends, such as hot and icing days and tropical nights in OECD Local Areas. </p>

<p style="color: #0965c1; font-weight: bold;"> The data is organized at Territorial Level 2 (TL2). To visualize the data at Local Area level, click on the corresponding TL2 indicator. </p>

<h3>Data sources and methodology</h3> <p align="justify">Indicators are estimated using <a href="https://developers.google.com/earth-engine/datasets/catalog/ECMWF_ERA5_LAND_DAILY_AGGR">ERA5-Land</a> data. Air temperature indicators correspond to the average annual air temperature at a height of 2 meters. Hot days correspond to the number of days when the maximum temperature exceeds 35°C. Tropical nights correspond to the days when the minimum temperature is above 20°C, and icing days to the number of days when the maximum temperature is below 0°C. 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 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> <h3>Further information</h3> For any question or comment, please write to <a href="mailto: RegionStat@oecd.org">RegionStat@oecd.org</a>
