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.
This Tech blog post describes two approaches that can help you collect high-quality data and minimize data gaps: automated data visualization for post-visit data QA/QC, and taking advantage of digital notes for field work and data processing.
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.
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
The Science How will forests cope as droughts become more frequent and severe? Piñon-juniper woodlands in the American Southwest are a model system for understanding the effects of drought on trees due to the frequent periods of water stress that characterize this region. Moreover, the dominant tree species in this ecosystem display markedly different drought… More
