Mapping Forest Biomass Density with ICESat-2 in ABoVE Circa 2020

Develop models using field data and lidar for biomass mapping, validate with LVIS data, assess biomass change post disturbances. Utilize ICESat-2, Landsat, and airborne lidar data for forest biomass mapping in the ABoVE domain.

Presentation Transcript

  1. Mapping Forest Aboveground Biomass Density for the ABoVE Domain Circa 2020 with ICESat-2 Laura Duncanson, University of Maryland, College Park Amy Neuenschwander, University of Texas at Austin Paul Montesano, NASA GSFC John Armston, University of Maryland Ralph Dubayah, University of Maryland

  2. Science Objectives Develop ICESat-2 biomass models representative of the ABOVE domain using existing field plot data and discrete return airborne lidar data 2) Produce a boreal forest biomass density map for the ABoVE domain 2019-2021 using ICESat-2 data and Landsat 3) Utilize data from the 2017 and 2019 LVIS campaign for product validation 4) Assess the biomass change associated with disturbance agents (harvest, fire, NSR) through the use of existing 35 year disturbance products and a 2010 biomass map

  3. ICESat-2 has launched as it collecting data globally Profile of ICESat-2 data through boreal forest NE of Edmonton, AB. ICESat-2 is a photon counting lidar system, so we need to establish new models to estimate biomass

  4. Methodology

  5. Remote Sensing This is an RS focused project using multiple sources of airborne lidar, ICESat-2 and Landsat • NEON, GLiHT over field plots to simulate ICESat-2 • LVIS over field sites to create validation airborne lidar maps • ICESat-2 and Landsat across full domain for ~2020 Biomass mapping

  6. NEON ALS data will be used to simulate ICESat-2, and this simulator will be validated against coincident real ICESat-2 data. These sites will also be used, in combination with other ABoVE domain field and lidar sites, to build ICESat-2 biomass models.

  7. Stakeholder Engagement Collaborators Mike Wulder and Joanne White at the Pacific Forestry Center (Canadian Forest Service) are leading engagement with Canadian government Peter Griffith and Collaborator Sabrina Delgado are working with potential first nations stakeholders at Great Bear Lake
