TMY3 is the latest dataset (1991- 2005) available from EnergyPlus, and the newer TMYx database (2004-2018) is available from Climate. Many applications just need an aggregate load shape. In the initial public dataset release (2021_1), there are two versions published: one with AMY weather, and another with typical weather data (TMY3). Formats include BINM, EPW, FIN4, CSV. A serially complete collection of hourly and half-hourly values of meteorological data and the three most common measurements of solar radiation: global horizontal, direct normal and diffuse horizontal irradiance. To distinguish between the old and new data sets, the new TMY data sets are referred to as TMY3. I checked the "Users Manual for TMY3 Data Sets" and it says that TMY3 files were derived mostly from a 1976-2005 period where available, and a 1991-2005 period of record for all other locations. 1 Release. ) The National Renewable Energy Laboratory (NREL) recently published new weather data for over 1,000 locations in the U. For example, if the last index in the TMY3 file was 1988-12-31 24:00:00 this becomes 1989-01-01 00:00:00 after calling read_tmy3(). A SAM weather file is a text file that contains one year's worth of data in hourly or subhourly time steps. TMY data sets represent hourly compilations of 12 months constructed using multiyear data sets. Dear April Showers, The short answer is that TMYx is a new (albeit confusingly ResStock testing weather data; Electricity Futures Smart DS weather data. Typical year data is commonly used for solar resource availability assessment at potential project sites or for running energy simulations to obtain P50 solar production estimates.
