We are happy to announce that Prof. Jose Fuentes of Penn State, is the 2018 recipient of the American Meteorology Award for OUTSTANDING ACHIEVEMENT IN BIOMETEOROLOGY. ‘For uncovering the significance and workings of key interactions among flora, fauna, and the atmosphere and their role in regional and global environmental change.’ Congratulations, Jose.

From the AmeriFlux-Community listserv. Thanks to Joydeep Bhattacharjee for asking, and David for this answer Joydeep: How do PIs across the network protect their equipment on towers against damage from lighting? David:  This question ought to unleash a flood of information and opinions, since lightning protection of sensitive instruments is a black art, similar to… More

What is Our Method?

(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

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….

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

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
