Climate/Weather Data Sources

The weather data on this site are derived from a number of public sources. This page contains information on each dataset (description, citation and web site where appropriate, EPWs last updated, and period of record). The EPWs were produced by translating the source data into the EPW format.

TMYx Source Data - see below for details on locations. TMYx dataset are created by the authors of this website. TMYx files are typical meteorological data derived from hourly weather data through 2023 in the ISD (US NOAA's Integrated Surface Database) using the TMY/ISO 15927-4:2005 methodologies. Currently, there are more than 17,300 TMYx locations supplied. For the 2024 release (this includes full TMYx, 2009-2023 TMYx, and 2007-2021 TMYx), the solar data for each site has corresponding solar radiation from the ERA5 reanalysis data set. The ERA5 data, courtesy of Oikolab, provides a comprehensive, worldwide gridded solar radiation data set based on satellite data. The 2004-2018 TMYx files use cloud cover and other variables to determine the solar. In all, there are more than 55,200 TMYx files on the site.

There may be up to four TMYxs for a location, e.g.,
EGY_AN_Aswan.Intl.AP.624140_TMYx,
EGY_AN_Aswan.Intl.AP.624140_TMYx.2004-2018,
EGY_AN_Aswan.Intl.AP.624140_TMYx.2007-2021,
EGY_AN_Aswan.Intl.AP.624140_TMYx.2009-2023.,
In these cases, there's a TMYx for the entire period of record, a second TMYx for the most recent 15 years (2009-2023) and a third TMYx for the years (2007-2021). Not all locations have recent data. There also may be a file from a previous publish -- 2004-2018 years.

TMYx - full dataset: all the years available from the ISD database. Typical Meteorological Year. The stat file and COMMENT1 line of the EPW will show details (see below). TMYx.year1-year2 contains a TMYx generation from just the period year1-year2 (usually 15 years). Typical Meterological Year. A minimum of 5 years is necessary to obtain a TMYx file.

TMYx full dataset example: Note that in the following example only 47 years were included though the full range (1957-2018) would be 62 years. Shown in the comments field of the epw files and on the stat file

  • Brazil - BrazFuture
    28 locations, Brazil state capitals plus Brasilia
    https://zenodo.org/records/13744587
    This dataset contains future weather files for energy simulation of buildings of the state capitals of Brazil plus the Federal District. The weather data is provided in EPW format, commonly used in EnergyPlus inputs. The periods of 2010, 2050, and 2090 are considered for generating the Typical Meteorological Years (TMY) for each location. Additionally, different climate model projections were used to enable an analysis of uncertainties in the simulation results. In this updated version, we have included the complete individual years used to develop the TMYs. This data is provided in CSV format and has been bias-corrected. The method for the data is described here: https://doi.org/10.1016/j.jobe.2024.109248

    A set of weather and climate data files have been produced for use in building energy models when designing new buildings. These are available at six locations around Ireland, shown in the map below. These come in the form of both a Test Reference Year (TRY) and 3 Design Summer Years (DSY), for both past data and future projections.
