Help Center - Frequently Asked Questions

This list of frequently asked questions (FAQ) addresses typical questions about facilities and services at NCAR and UCAR. If you don't find an answer here, in the dropdown menus above, the links at the right, or by using our site search, please fill out our web form to email us.

Finding data

U.S. weather data for temperatures, winds, precipitation (rainfall/snowfall/hail), and other key measurements can usually be obtained from the office of the state climatologist in the region(s) you're interested in.

In Colorado, for example, the state climatology office is the Colorado Climate Center at Colorado State University.

To find a comparable office in another state:

  • Visit (American Association of State Climatologists). The site also provides information and links to six regional offices (see Regional Climate Centers, below)
  • Or search for "state climatologist" plus the state's name in your favorite search engine.
  • For international locations, try a similar search engine approach.

What if I need data from more than one U.S. state?
