Climate/Weather Data Sources

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

TMYx - see below for details on locations. TMYx files are derived from ISD (US NOAA's Integrated Surface Database) with hourly data through 2017. TMYx files are created using the general principles from the IWEC (International Weather for Energy Calculations) Typical Meteorological Years that was published in 2001. TMYn files are created from NSRDB (National Solar Radiation Database from NREL - National Renewable Energy Laboratory) downloads - this data was used in the Caribbean where there was little or no ISD data). The resultant files have been peer reviewed by interested parties.

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 46 years were included though the full range (1957-2017) would be 61 years. Shown in the comments field of the epw files and on the stat file
