Rapid Response Flux Systems

AmeriFlux Management Project (AMP) has two Rapid Response flux systems available to take advantage of unique research opportunities that come up suddenly, or may have short measurement windows. Such situations might include: measuring ecosystem fluxes following a disturbance, such as a wildfire, an infestation of borer beetles, or a habitat restoration. Site PIs may need to quickly start useful measurements (ecosystem recovery). They also may plan to seek funding to purchase a new system for long-term measurements, so the Rapid Response flux system can fill the gap in time. Or they might make measurements just for a short time..


These will be loaned for a maximum of three years for each opportunity. Selection of recipient is managed by Margaret Torn, AMP lead PI, in consultation with AMP co-PI Dennis Baldocchi and a subcommittee of the AmeriFlux Science Steering Committee. AMP pays for shipping to the site PI. The site PI pays for shipping to return the system to AMP. If a Rapid Response system is damaged beyond repair on-site, AMP expects the site PI’s institution to pay replacement costs.


These systems include a sonic anemometer, gas analyzer, datalogger, radiometers, and basic meteorological sensors. At this time, below-ground sensors are not provided. Sensors are fully calibrated before they are loaned to site PIs. Eddy covariance sensors on RRSystem1 include a CSAT3A, LI-COR 7500, and LI-COR 7200. Eddy covariance sensors on RRSystem2 include a CSAT3A, EC150, and EC155. Gill sonic anemometers are available in lieu of the CSAT3A. Systems may require some customization. Assembly depends on the requirements of the site. The Tech Team will manage delivery, advise the recipient on deployment, and maintain the system when it is returned. NOTE: AMP cannot provide towers or permanent infrastructure.


Any scientist in the AmeriFlux domain (the Americas) is eligible to apply; it is not restricted to current AmeriFlux PIs. Successful applicants will demonstrate sufficient technical knowledge and site security for a successful deployment, register the rapid-response site as an AmeriFlux site, and upload data promptly.

Application Process

  • Send an email to ameriflux@lbl.gov
  • Provide your name, institution, current AmeriFlux siteIDs (if any), and contact information
  • Describe the research opportunity and the value of taking measurements quickly
  • Describe your technical capability to collect high quality data
  • Describe the location of the site, including coordinates, access, land ownership, vegetation cover, and existing (or forthcoming) infrastructure (power, communications, towers, etc). Include a Google Earth image of the site, marked with prevailing wind direction.
  • Describe the site’s security, and any potential risks to instruments on site.
  • Propose start and end dates of the loan

An AMP team member will contact you, and discuss your application.
