Looking for the place to put a data center for free cooling? Or maybe for photo voltaic. You need weather data.
AWS blogs about 20 GB of daily weather data.
New Public Data Set: Daily Global Weather
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.

National Climate Data Center (NCDC)
Data originally collected as part of the Global Surface Summary of Day (GSOD) by the National Climactic Data Center (NCDC). Data collected, transformed, and uploaded by Infochimps.org.
Global summary of day data for 18 surface meteorological elements are derived from the synoptic/hourly observations contained in USAF DATSAV3 Surface data and Federal Climate Complex Integrated Surface Data (ISD). Historical data are generally available for 1929 to the present, with data from 1973 to the present being the most complete. For some periods, one or more countries’ data may not be available due to data restrictions or communications problems. In deriving the summary of day data, a minimum of 4 observations for the day must be present (allows for stations which report 4 synoptic observations/day). Since the data are converted to constant units (e.g, knots), slight rounding error from the originally reported values may occur (e.g, 9.9 instead of 10.0).
