Hourly Climate Data from ERA5 Reanalysis, with gap-free, global coverage from 1940 to present. Time-series hourly weather data spatially interpolated from ERA5 reanalysis dataset (0.25 deg x 0.25 deg lat/lon), from 1940 onwards with global coverage. Valid climate parameters include: 'temperature', 'dewpoint_temperature', 'wetbulb_temperature', 'relative_humidity', 'humidex', 'urban_temperature', 'surface_solar_radiation', 'surface_thermal_radiation', 'surface_direct_solar_radiation', 'direct_normal_solar_radiation', 'surface_diffuse_solar_radiation', 'wind_speed', 'wind_direction', '10m_wind_gust', '10m_u_component_of_wind', '10m_v_component_of_wind', '100m_u_component_of_wind', '100m_V_component_of_wind', 'surface_pressure', 'total_cloud_cover', 'soil_temperature_level_1', 'soil_temperature_level_2', 'soil_temperature_level_3', 'soil_temperature_level_4', 'sea_surface_temperature', 'skin_temperature', 'total_precipitation', 'snowfall'
