(Dennis Baldocchi, author.) I have a new graduate student who is taking introductory classes with a diverse group of environmental science students. In their discussions, they are comparing how each one does their science. So in our weekly discussions, the question came back to me as to “What is our Method?” This is a good… More

Three AmeriFlux scientists were recent recipients of awards from the American Meteorological Society THE CLARENCE LEROY MEISINGER AWARD Ankur Desai For innovative contributions toward improving the observation and modeling of biosphere-atmosphere exchanges across a range of spatial and temporal scales. THE CHARLES E. ANDERSON AWARD José Fuentes For outstanding, sustained efforts to promote diversity in… More
Several activities at AGU Fall 2015 for members of the AmeriFlux Community. Especially fun for this year: AmeriFlux Town Hall to kick off the AmeriFlux Network’s 20th Anniversary! That’s on Thursday, Dec 17, 12:30 – 1:30PM, Moscow West – 2004. Send info on sessions and activities to include in list below to ameriflux@lbl.gov. We’ll also… More
Yue, X., N. Unger, T. F. Keenan, X. Zhang, and C. S. Vogel. 2015. Probing the past 30-year phenology trend of US deciduous forests. Biogeosciences 12:4693-4709. doi:10.5194/bg-12-4693-2015 “Phenology is experiencing dramatic changes over deciduous forests in the USA. Estimates of trends in phenology on the continental scale are uncertain, however, with studies failing to agree on… More
The 8th Colorado Flux Course (#fluxcourse; http://www.fluxcourse.org/) was recently convened up at Niwot Ridge, Colorado. Twenty-five students from across the US and globe came to hear lectures on eddy covariance, flux instrumentation, leaf cuvette systems, land surface modeling, remote sensing and data fusion modeling. Students also toured the Niwot Ridge AmeriFlux site (US-NR1) and visited NEON…. More
Evapotranspiration based on equilibrated relative humidity (ETRHEQ): Evaluation over the continental U.S. From Water Resources Research 51(4),2951-2973, 2015. DOI: 10.1002/2014WR016072. Copyright (2015) American Geophysical Union. Guido Salvucci’s group at Boston University are avid users of AmeriFlux data. There is a new paper in Water Resources Research that explores a way to estimate watershed scale evaporation…. More
Lianhong Gu’s book review on Terrestrial Biosphere-Atmosphere Fluxes (2014), by Russell Monson and Dennis Baldocchi, is now available at ESA 2015, Book Review, Ecology 96:1736: “Fluxes as functions of ecosystems and drivers of atmosphere.” Read the review at http://dx.doi.org/10.1890/BR15-24.1. “Monson and Baldocchi, two accomplished researchers and admired educators, masterfully incorporate real equations into a scientific storytelling… More
There is growing interest to use sun induced fluorescence to estimate ecosystem photosynthesis from space. This new paper from Yang et al tested indices from hyper spectral reflectance measurements with gross carbon fluxes at Harvard forest. Results look interesting and the response between SIF and GPP is much more linear than that between GPP and… More
If you missed the 2015 AmeriFlux Data and Tech Workshop, you can now view videos of several presentations from the workshop online. These presentation may be of use to AmeriFlux tower teams, AmeriFlux data users, and anyone with interest in flux, meteorological, and BADM data. Follow the links below to watch the presentation videos. See… More
Congratulations to Margaret Torn, AmeriFlux Management Project lead PI! Margaret received an honorary doctorate from the University of Zurich last Saturday, in recognition of her efforts to deeper understanding of biogeochemical processes and their climate implications of the soil-plant-atmosphere system, which contribute to science-based solutions to sustainable development of natural resources. She was one of… More
