New Public Data Set: Daily Global Weather
The folks at Infochimps have just released the Daily Global Weather Public Data Set.
This 20 GB data set incorporates daily weather measurements (temperature, dew point, wind speed, humidity, barometric pressure, and so forth) from over 9000 weather stations around the world. The data was originally collected as part of the Global Surface Summary of the Day (GSOD) by the National Climactic Data Center and is available from 1929 to the present, with the data from 1973 to the present being the most complete.
The map at right contains one yellow dot for each data collection station.
