TIPS FOR VIEWING THE ANIMATIONS
The Alaska Geospatial Climate Animations were created for scientific visualization of patterns in long-term average temperature and precipitation -- across the state's various landscapes, and month-to-month through the seasons. As such they will help with modeling or interpretation of modern climate phenomena, as well as paleoclimatic records. The animations should also be useful for earth science education and public outreach.
Learn more about the animations, and what they reveal about Alaska's climate patterns in space and time. The pages below describe such features as seasonality, continentality, coastal effects, inversions, elevation effects, rain shadows, and other phenomena:

These movies were created as part of EarthSLOT, a 3D GIS and terrain visualization application. Through an online interactive interface, you can fly wherever you'd like -- across Mean Annual Temperature and Total Annual Precipitation -- by taking the following steps:

Learn more about the PRISM data and how the animations were created.
Please note that the monthly animations do not illustrate warming and other effects of climate change observed for the last several decades. For more information on this topic, please see a recent report, the Arctic Climate Impact Assessment (ACIA), and the Alaska Climate Research Center's spotlight on Temperature Change in Alaska.
The Alaska Geospatial Climate Animations are based in part on work supported by the National Science Foundation, Office of Polar Programs, Arctic System Science Program (Grant No. OPP-0100120). Any opinions, findings, and conclusions or recommendations expressed in this material are those of the authors and do not necessarily reflect the views of the National Science Foundation. The animations wouldn't be possible of course without the PRISM data and the pioneering spatial modeling efforts of the Spatial Climate Analysis Service. Thanks also go to Peter Prokein and Matt Nolan (University of Alaska Fairbanks) for assistance with the 3D visualizations, as part of the EarthSLOT project.
