Where can I find TMY3 data?
The TMY3 data are available for download via the World Wide Web. Data may be accessed at http://rredc.nrel.gov/solar/old_data/nsrdb/1991-2005/tmy3.
What is the difference between TMY2 and TMY3?
The second edition of the TMY is called “TMY2”. The third, and latest TMY collection (TMY3) was based on data for 1020 locations in the USA including Guam, Puerto Rico, and US Virgin Islands, derived from a 1976-2005 period of record where available, and a 1991-2005 period of record for all other locations.
What is TMY3 data?
A typical meteorological year (TMY) is a set of meteorological data with data values for every hour in a year for a given geographical location. The data are selected from hourly data in a longer time period (normally 10 years or more).
What is TMY solar?
The most common data for describing the local solar climate is through what is called Typical Meteorological Year data (TMY). To determine TMY data, various meteorological measurements are made at hourly intervals over a number of years to build up a picture of the local climate.
What is TMY weather file?
TMYx files are typical meterological data derived from hourly weather data through 2018 in the ISD (US NOAA’s Integrated Surface Database) using the TMY/ISO 15927-4:2005 methodologies. This site contains KML map links to files contained on the site.
What is the full form of TMY?
TMY means “Tell Me Why.”

How is TMY calculated?
To determine TMY data, various meteorological measurements are made at hourly intervals over a number of years to build up a picture of the local climate. A simple average of the yearly data underestimates the amount of variability, so the month that is most representative of the location is selected.
How do I open EPW files?
A universal file viewer is the way to go when you have EPW files that can’t be opened by any other program. Install a universal file viewer like File Magic (Download) and see if it will open your EPW file. Remember that if your file is not compatible, the universal file viewer will only open it in binary format.
What is Epw file format?
Weather data file saved in the standard EnergyPlus format; used by EnergyPlus energy simulation software, developed by the U.S. Department of Energy (DoE); contains weather data that is used for running energy usage simulations.
How do I download weather data from the NREL?
The NREL National Solar Radiation Database (NSRDB) provides free time series weather data for many countries of the world. You can use the Download buttons on SAM’s Location and Resource input page to download NSRDB data directly from SAM. Note about snow depth data.
What is a typical meteorological Year (TMY) data set?
A typical meteorological year (TMY) data set provides designers and other users with a reasonably sized annual data set that holds hourly meteorological values that typify conditions at a specific location over a longer period of time, such as 30 years.
Original typical-year hourly data files with additional data and documentation for legacy NREL NSRDB 1961 – 1990 (TMY2), 1991 – 2010 update (TMY3), and 1998 – 2014 update (TMY3). TMY2 files are also available in SAM CSV format ( ZIP 23.3 MB ).
How do I get the most complete solar radiation data?
For the most complete, easy-to-access data, NREL recommends using the NSRDB Viewer instead of prior versions of the NSRDB. The National Solar Radiation Database 1961-1990 contains 30 years of solar radiation and supplementary meteorological data from 237 National Weather Service sites in the United States and its territories.
