We learned with great sadness that Nobel laureate Paul J. Crutzen passed away on January 28. His work on the decomposition of ozone in the atmosphere not only earned him a share of the Nobel Prize in 1995, but is an impressive example of evidence-based, scientific advocacy directly shaping policy. The ban on chlorofluorocarbon compounds… More
Professor Jim Shuttleworth sadly passed away on Sunday 20 December, surrounded by his family. Jim was a pioneer in the field of hydrometeorology and best known for his innovative contributions to our understanding of evaporation. After finishing a PhD in high energy nuclear physics at the University of Manchester in 1971 Jim joined the Institute… More
It’s not often that you get to see a total solar eclipse from your own back yard. It’s even rarer when your eddy covariance flux site, 300 miles away, is also in the path of totality. That’s just the situation we found ourselves in. On August 21, 2017, a total solar eclipse crossed our research site in the Nebraska SandHills (US-SdH). Being a long-time amateur astronomer, it presented an opportunity that we just couldn’t miss.
I thought you’d find the following reads intriguing. Both are lead-authored by Matt Roby, a Ph.D. student, at the University of Arizona’s School of Natural Resources and Environment. Matt’s been busy working on his dissertation on climate change impacts on ecosystem carbon and water cycling in dryland regions with a minor in science communication. In… More
The following is a description of the workflow that we use at the ChEAS (Chequamegon Ecosystem-Atmosphere Study) core-site cluster based at the University of Wisconsin to create real-time plots of our data. It allows us to look for inconsistencies and changes in data over time.
Due to COVID-19, the entire AmeriFlux Management Project (AMP) has been working from home since March 16 following shelter-in-place orders from public health authorities in the San Francisco Bay Area. Read about how we are adapting.
To capture the spring release of greenhouse gasses from bog lakes, a team of intrepid UW-Madison researchers installed eddy covariance buoys on two frozen bog lakes in northern Wisconsin in March. These buoys provided under the loaner instrument program (LI-7700) by the AmeriFlux Management Project for the AmeriFlux Year of Methane are continually measuring carbon dioxide and methane fluxes and will continue doing so as ice melts and as the buoys settle into their summer home on the open water.
Dec 7-8 2019 The Coastal Carbon Research Coordination Network (CCRCN) held its second working group workshop this past December at NASA’s AMES Research Center in Mountain View, CA hosted by the US Geological Survey. This year’s working group is focused on improving predictions of methane emissions from coastal wetlands. Specifically, we aim to compile all… More
This post was authored by Camilo Rey-Sanchez (current PostDoc at UC Berkeley, Biomet Lab) for the AmeriFlux Year of Methane. If you have done chamber measurements of methane (CH4) flux in wetlands, you have probably noticed a high spatial heterogeneity in your data. If you are lucky, you have gone further to identify certain… More
AmeriFlux showcased the Year of Methane action year at the 2019 Annual Meeting with an oral session, methane posters, and three methane breakout discussions. Ruminants, Forests, and Wetland Management The Year of Methane talks illustrated the variety of new directions enabled by methane flux measurement. Dave Hollinger, a Forest Service research scientist, gave the invited… More
