News about this website

This website contains typical, single-year weather data files in EPW format from many publicly available data sets from around the world.

July 2018 - 22 Korean (South Korea) weather files are available - from PHIKO - Passive House Institute Korea

Apr 2018 - New Simulation Weather Data Set for Mexico, Caribbean, Central and South America and Antarctica Available

A new simulation weather data set (TMYx) is now available for locations in Mexico, Caribbean, Central, South America and Antarctica, derived from the ISD (US NOAA's Integrated Surface Database) with hourly data through 2017. TMYxs for more than 1600 locations in the Americas are available. There may be two TMYxs for a location, e.g., MEX_MEX_Cuidad.Mexico-Juarez.Intl.AP.766793_TMYx, and MEX_MEX_Cuidad.Mexico-Juarez.Intl.AP.766793_TMYx.2003-2017. In these cases, there's a TMY for the entire period of record and a second TMY for the most recent 15 years (2003-2017). Not all locations have recent data.

TMY3a (US and some others), TMY (US and some others), CWEC (Canada), CTZ (California Climate Zones), CSWD (Chinese Standard Weather Data), BBSR (Germany), NIWA (New Zealand), RMY 2012 (Australia), IMS (Israel), ITMY (Iran), SWERA (multiple countries), INMET and TRY (Brazil), City University of Hong Kong, ISHRAE (India), IMGW (Poland), KISR (Kuwait), JGMY (Japan generated weather), TurTMY (Turkey), ArgTMY (Argentina) and Uruguay (AMTUes) sources have been loaded. Stay tuned to this page for further updates.

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) 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.

A papers section has been added.
