Remote sensing can help scientists interpret carbon, water, and energy flux measurements at eddy covariance sites by providing contextual information on community composition and vegetation function, as well as scale fluxes globally. Additionally, flux data can inform remote sensing measurements which do not directly measure carbon and water fluxes.
Workshop goals:
- Build awareness of the existing synergies, challenges, and opportunities between remote sensing and flux science.
- Foster new cross-disciplinary connections to identify and address knowledge gaps and uncertainties associated with both flux and remote sensing data.
- Increase the accessibility, usability, and standardization of remote sensing data so that it can be used to inform flux data, following the FAIR principles.

Attendance is free, as well as lodging for up to 32 participants (preference given to early career). Additional lodging can be found in nearby town of Nederland but will not be covered by the workshop (please specify preference in application). Food will be provided for all participants. A small number of travel grants (air/ground) are available and will be awarded by organizing committee–availability and willingness to help with event logistics and sessions during workshop are a plus.

These data will be used to: (1) examine empirical relationships between SIF and GPP for comparison with previous studies, (2) drive process-based models such as the Soil Canopy Observation of Photochemistry and Energy fluxes model (SCOPE) and the Mechanistic Light Reaction–SIF model (MLR-SIF) to isolate the contribution of plant physiology to the SIF signal and generate independent estimates of GPP, respectively, and (3) assess the ability of SIF to provide information on reductions in GPP due to stress, such as extreme heat. | |||
| Eleanor Serocki | I aim to present a poster of my dissertation, which is working to link long term CO2 and CH4 flux data to satellite based remote sensing.This project leverages 16 years of flux data, both from static chambers and a flux tower, to model carbon flux based on water table depth, which has been shown in earlier research to closely reflect carbon flux. Since both Multispectral and Synthetic Aperture Radar approaches have been successful in other peatlands for locating water table depth, we will find the best practice within Alaska’s rich fen systems, and then apply the flux to the water table model in order to map carbon flux. The goal is to create a best practice for mapping water table depth, leading to an easily implementable, spatial tool for understanding gas flux in Alaska’s rich fens, which are vital to the carbon story. Though this work is in early stages, this project builds on long term research within the Alaska Peatland Experiment (APEX) of the Bonanza Creek Experimental Forest, part of the National Science Foundation’s Long Term Ecological Research program, and aims to create a methodology for understanding flux at scale for one of Alaska’s most common cover types. | |||
