This repository contains weather data files for four cities in the main climatic zones of Catalunya, Spain — Barcelona, Lleida, Manresa and La Seu d’Urgell representing the coastal, continental, pre-coastal and pre- and Pyrenean Mediterranean climates, respectively. For each location, datasets represent typical and extreme meteorological conditions for the present (2020s), mid-term future (2050s), and long-term future (2090s).

For each city there are several sub-folders:

- BiasCorrected_CSV folder contains three comma-separated value (CSV) files, each comprising hourly weather data over 20-year periods representing the 2020s, 2050s, and 2090s. These datasets are derived from climate projections obtained through the COordinated Regional Downscaling EXperiment (CORDEX), aligned with the RCP 8.5 scenario outlined in the IPCC Fifth Assessment Report (AR5). To improve reliability, the raw projections have been adjusted for bias using historical meteorological records from local weather stations (in Barcelona - Raval, Lleida - Raimat, Manresa - Sant Salvador de Guardiola and La Seu d'Urgell) Servei Meteorològic de Catalunya.

- The TMY_EPW folder includes weather files in the EnergyPlus EPW format, representing Typical Meteorological Years (TMYs). Each file provides hourly climate data for a full year, covering all key variables required for building thermal simulations, such as air temperature, relative humidity, atmospheric pressure, wind speed and direction, and global horizontal irradiance. These files are constructed from 20-year climate series corresponding to the present (2020s), mid-century (2050s), and end-century (2090s) periods, using a standardized method that selects the most representative months across the time spa.

- The Heatwaves_EPW folder contains annual weather files in EPW format for EnergyPlus simulations, specifically representing years with significant heat wave (HW) events. For each 20-year period and city, selected years include those marked by the most intense, longest, and most intense heat waves identified within the dataset. One representative file is provided for each time slot: Present (2006–2025), Mid-century (2041–2060), and End-century (2081–2100).
