One of the major goals of the DESDynI mission is to estimate biomass dynamics on an annual basis at high spatial resolutions. Planned approaches for achieving this goal will rely on DESDynI measurements as the primary input. Through a four-year project funded by NASA’s Terrestrial Ecology program, we will develop new approaches that integrate DESDynI measurements with the long-term record of Landsat observations for improving and extending DESDynI predictions of biomass and biomass dynamics. Major objectives of this project include:
(1) Develop an approach for integrating age estimates and multispectral trajectories from the Landsat record with anticipated height observations from DESDynI to map height, biomass and biomass changes across the landscape through time.
(2) Assess the spatial and temporal variability of biomass dynamics over the DESDynI mission length at various spatial scales to quantify expected disturbance and growth rates from which required measurement accuracies for DESDynI may be determined.
(3) Integrate age structure maps from Landsat with height and biomass products developed through Landsat/DESDynI fusion to improve and validate ecosystem model estimates of terrestrial carbon flux.
(4) Scale up our Landsat-DESDynI integration approach to produce spatially and temporally resolved, state level assessment of biomass dynamics for nearly four decades, and use these products to drive ecosystem model estimates of carbon flux.
The purpose of this poster is to provide an overview of this project, and to highlight results achieved during the first project year.
