Post and photos by Chad Hanson Many field sites do not have access to line power and run on solar. This post is intended to share a recently built simple solar system and the design considerations that went into it. Hopefully this will help others as they design and maintain their own systems and encourage… More

During this past AmeriFlux PI Meeting, Gil Bohrer and Tim Morin presented a live demonstration of their Portable Canopy Lidar (PCL), shown in Figure 1, which was developed by their team. The system is based on Lidar (light detection and ranging), which uses pulsed laser light to measure distances based on “time-of-flight.” In the demo,… More
Every spring on the Sevilleta grasslands (elevation 5000 ft), strong northeast winds blow the tumbleweeds down the Rio Grande valley. The tumbleweeds stick to anything that stands out—like the AmeriFlux 3-meter flux tower, US-Seg. Jonathan Furst, photographer and NMEG research scientist, deals with them every year after the seasonal die-off. “They stick to each other. They’re covered with… More
Good metadata management is especially important when data are shared across a large community. Therefore, AmeriFlux is encouraging all sites to fill out an instrument operations (Instrument_Ops) BADM template within the next three months. Both instrument BADM templates have recently been updated: The updated Instrument_Ops template is designed for the submission of basic instrument operations… More
At the 2015 Ameriflux Principal Investigators Meeting in Washington DC, 35 people participated in a World Cafe session to brainstorm about the Next Big Ideas in climate research. Below are listed the primary themes that emerged from discussions. Tables Three rounds of discussion were held at each table. At the end, participants used dots to indicate favorable… More
At the 2015 AmeriFlux PI Meeting in Washington DC, Tim Morin demonstrated the use of his portable LIDAR gear.
This year’s AmeriFlux PI Meeting (January 29-30, 2015) was held jointly with the NACP PI Meeting. We had 128 registered participants, 48 posters, 3 vendors, 11 science talks, 6 breakout topics, a world cafe, a LIDAR demo (indoors—it was snowing outside), an “AmeriFlux Issues” hour, a “Doctor is In” booth, and an “Early Career Scientists”… More
Guest blog by David Moore, who organizes this annual course, with the help of many others. Fluxcourse 2015 – 8th annual summer course in flux measurements and advanced modeling We will be running the annual Fluxcourse this year July 20-31 2015. We plan to hold it at the Niwot Ridge Mountain Research Station once more, with the help… More
Now posted in our Resources, the white paper, “An AmeriFlux network perspective on urban and managed systems,” brings together expertise of the AmeriFlux community to identify gaps and offer recommendations to improve understanding of human-dominated and managed landscapes. It provides a brief review of socioeconomic, energy, water, ecological, and biogeochemical aspects of human-dominated ecosystems, and highlights… More
Congratulations to Beverly Law, who was honored as 2014 AGU Fellow yesterday at a ceremony during AGU Fall Meeting, San Francisco, California!. This honor is in recognition of her pioneering contributions integrating flux measurements, remote sensing, and ecosystem models from regional to global scales. Bev Law is well known to the AmeriFlux community, where she has… More
