Investigating weather data with xmACIS2

Single points of weather data are often not very interesting. You can look at see what the high temperature was on a given day, but so what? Trends and streaks are much more interesting. How many consecutive days above 60°F has your city had in January? When’s the last snowfall greater than 2″?

If you’re looking to answer those kinds of questions, the NOAA Regional Climate Centers (RCCs) has a tool for you. xmACIS2, part of the Applied Climate Imitation System, provides a free web interface to get that data. xmACIS2 provides a variety of configurable queries to provide data in tabular or graphical form.
