Year of Remote Sensing

Theme year logo (Designed by Koong Yi)


The goal of the Theme Year of Remote Sensing (YoRS) is to encourage research that combines eddy covariance and remote sensing at all levels, from ground to spaceborne, throughout the AmeriFlux community.

Potential community-led activities for the theme year include but are not limited to, theme-related webinar series, scientific and technical workshops, special sessions at scientific meetings, the instrument loaner program, and so on. These efforts will be led by the AmeriFlux community (You! 😉) and supported by the AmeriFlux Management Project (AMP).

YoRS Organizing Committee

The Year of Remote Sensing Organizing Committee was formed to brainstorm theme-year-related activities that can help the community get more familiar with remote sensing products/techniques and apply them to their research. The ideas listed in the table below are only the beginning and will keep evolving. You can also be involved and contribute to our community by suggesting ideas, organizing/leading activities, and more. We would like to hear your ideas!

Strategic plan for the YoRS

ObjectivesSub-goalsAction plan
Synthesize research topics integrating RS-ECAdvance science from RS/Eddy flux synergies

- Spread the word to collect input (mailing list, announcement at Annual Meeting and AGU sessions, etc.)

- Host workshop for data synthesis

- Create white paper/document summarizing topics, share open invitation for contributors
Seek feedback from ECOSTRESS Team. What worked? What could be improved?
Scaling fluxes from canopy (i.e., EC scale) to watershed/region (i.e., RS scale)
NEE flux partitioning (remotely-sensed GPP validation)
Can RS help with validation of Natural carbon solutions (e.g., multispectral and lidar integration)?
Expanding the siloed view of RS: when and how to include the horizontal processes.
Pilot study with different focal points at one of the AmeriFlux sites?
Identify critical (e.g., fast change) ecosystem/areas and propose EC deployments
Improve representation in under-represented regions and reduce RS data product uncertaintiesWe want more representation in Africa, tropical rainforests, savanna, and boreal.AmeriFlux Rapid Response System Program to identify
under-represented regions (i.e., South America) and reduce RS data product uncertainties. Can use RS (e.g., high-res hyperspectral) to determine where towers are needed.
Ensure standardization.AmeriFlux Slow Response System Program (communicate with funders, programs about long-term investments; working with and supporting global networks).
Support open data (e.g. eco-hydrological extremes).Identify existing towers and teams collecting data and not yet included in flux network data (e.g., ABoVE, LTER/LTAR, etc.), and reach out for including them.
Training remote sensing toolsMake RS become regular tool/data of EC community.Standardization, workshop/ data integration w/FLUXNET Coop.
- Identity toolboxes available to facilitate the
use of RS/EC data products (GitHub, R toolbox,...).

- Develop a platform for users with information on flux techniques and RS
(similar to HydroLearn or PSU meteo300).
Solicit community input on needs and known tools --> create compilation (reference:
Workshop for novel RS tools (optical/thermal/microwave, Google Earth Engine,
GEDI, Lidar for canopy structure)
Introduce AmeriFlux to SpecNet Community Meeting Oct 27-28
How can we make RS data collected on flux towers more readily available?Database: integration with AmeriFlux
Data synthesis activities; discussions with data hosts/daac's; create vision of standardization and side-by-side RS/flux tables
CommunicationExpand knowledge of strengths/limitations, when/how to use and not use.
workshops, webinars, blogs, tweets, Eos-type articles
Webinars on existing data products relevant to both communities (AmeriFlux / RS). Specific Topics? (SIF)AmeriFlux Webinar Series (identify speakers), Session at conferences
Potential papers from the YoRS initiative:
- Review of state-of-the-art (e.g., on scaling leaf-canopy-regional-global)
- Perspectives papers:
- “Announcement” / “Call-to-action” paper on or similar (prior or simultaneous with AmeriFlux Annual meeting announcement of YoRS)
- Reports from activities: workshops, etc.
Identify leads to write papers, reports
Virtual workshops (e.g., entry-level lecture/tutorial series)
