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
