Weather data. MOUNTAIN VIEW MOFFETT FLD 11 31 64. *ASHRAE has compiled 30 years of dry-bulb design temperature data in the 2005 ASHRAE Handbook of. Weather Data Viewer version 6.0 enables users to view the frequency tables and joint frequency matrices for all 8,118 stations provided in the 2017 ASHRAE Handbook.
What is the basis of the IWEC2 weather files? IWEC2 weather files were developed through ASHRAE Research Project RP-1477, 'Development of 3012 Typical Year Weather Files for International Locations,' by White Box Technologies, Moraga, California, Y. Joe Huang, Principal Investigator. These files are derived from meteorological reports of weather stations around the world that are archived in the Integrated Surface Hourly (ISH) data base maintained by the National Climatic Data Center (NCDC). For these selected locations, the ISH database contains weather observations on average at least four times per day of wind speed and direction, sky cover, visibility, ceiling height, dry-bulb temperature, dew-point temperature, atmospheric pressure, liquid precipitation, and present weather for at least 12 years of record up to 25 years.

Because the ISH database contains no measured solar radiation, the hourly total horizontal solar radiation is calculated using an empirical Zhang-Huang Model based on the sun-earth geometry, reported cloud cover, temperature difference from three hours previously, relative humidity, and wind speed, which is then adjusted on an hourly basis using the new ASHRAE Clear Sky Model to correct for statistical noise in the hourly profile. A second empirical Gompertz Function Model is used to calculate the direct normal solar radiation based on the solar angle and the ratio of the derived total global horizontal compared to the extraterrestrial solar radiation. Other models then use these derived solar radiation values to calculate various illuminances (global horizontal, direct normal, diffuse horizontal) and zenith luminance that are useful for daylighting studies.
