hourly meteorology for anywhere on Earth free!

Recommended Posts

Over the past 40 years, I have conducted many simulations of various power systems. One thing I've always needed to drive these simulations is meteorological data. You can get this free from over 15,000 weather stations around the world. It is called the Global Surface Summary of the Day (GSOD) and is maintained in a database on servers located in North Carolina operated by the National Climate Data Center (NCDC) of the US National Oceanographic and Atmospheric Administration (NOAA). The files are by year on ftp://ftp.ncdc.noaa.gov/pub/data/gsod in UNIX tar balls. You will need the untar and gzip utilities or you can use WinZip. Pick the station or stations nearest the site in question. Stations are kept in the file called isd-history. You can extend the daily min, max, and averages into hourly values, as illustrated in the attached Excel spreadsheet. I wrote a program that does all this automatically plus interpolates temperatures and barometric pressure over the whole earth. This isn't computer-generated speculation. It's actual recorded data, spatially interpolated. The black specks are the stations reporting data on that particular day.
