See our data access page to download archived webcam images from past years.   Currently, these are rather large files for an entire calendar year.  Contact us if you would like a specific date range or have trouble downloading the archives.

Dr. Eugenie Euskirchen is presenting CO2 and CH4 data summaries from the Imnavait Creek sites at the 2013 AmeriFlux/NACP meetings in Albuquerque, New Mexico.  Her poster is available on our Presentations page, under the Publications menu.

Images from our four webcams at Imnavait Creek join the PhenoCam network.  This is an effort to improve understanding of vegetation phenology via a network of canopy cameras.  Images from our phenology webcams begin in June 2012 and can now be found in the 'Affiliated sites' section of the PhenoCam website: http://phenocam.sr.unh.edu/webcam/gallery/

Examples from the Ridge Phenocam, including some caribou passing through:

Research examining seasonal and spatial variation in plot-level CO2 fluxes at our flux tower sites will be published in the Journal of Geophysical Research.  Lead author and AON collaborator Dr. Anja Kade classified tundra vegetation types within the 3 flux tower footprints and then measured chamber-level CO2 fluxes in dominant vegetation types during both the growing season and winter months.   Scaling net ecosystem exchange rate of CO2 from plot-level to tower-level produced generally good agreeement between methods during summer, but not during wintertime.

Additional webcam images can now be viewed on this site, click the 'Webcam Gallery' menu item.  We hope to create downloadable archives of images in the future.  In the meantime, please use the 'contact us' link at right to obtain past image files.
