May
02

Our Imnavait Cr datasets are now inclusive of 2021. We have updated the Ameriflux data sets as well, now including GF (gapfilled) as well as 2021 data. See https://ameriflux.lbl.gov/data/download-data/ -> sites are US-ICs, US-ICt and US-ICh.

To download all available years in a single file from our website, scroll to the bottom of the 'Year' filter, and select 'ALL'. For Imnavait, that is 2007-2021 in the Ameriflux format. Please don't hesitate to ask questions about our data, contact our data manager at

Please note that our sensor setups have change in 2021 as well. At Imnavait Cr we have added FCH4 at tussock and heath in Apr 2021, and in Sept 2021 changed the IRGAs to LI-7500DS.

In other news, despite the pandemic and the war creating extreme difficulties in working at our Cherskiy site, we are successfully collecting flux data once again at the Pleistocene Park tall tower. We have CO2/H2O and CH4 flux monitoring there since Sept 2021, ongoing.

Fall 2016 Data and Website Update

Sep
15
Updated Imnavait data is now available, processed up to Nov 2016. In May, we replaced all the Licors at Imnavait with closed path LI-7200 units. We are still running an open path methane analyzer at Wet Sedge site. Please contact us with any questions. Cherskiy data is available up to August 2016, when the system was disconnected. Unfortunately, this will be the end of the Russia site data collection for now. We hope that funding will become available to reinstate the project. The webcam galleries have been replaced, so that the most recent 24 hours is available. Please contact us if you wish to have access to older images. Or simply visit the Phenocam website and search for imcr--- sites. Click 'browse images' for historical data. https://phenocam.sr.unh.edu/webcam/gallery/
