Census + TLS + UAV lidar + airborne lidar in Australia! Led by PI @ArmstonJohn’s @NASA CMS project with huge support from @CSIRO, Queensland DESI and UQ we measured a range of vegetation biomass for calval of satellite products @GEDI_Knights @NASA_Carbon @qldscience @UQ_News

Extremely exciting news for the future of Satellite #lidar! #EDGE has been selected to the next round by @NASA! What is EDGE? Led by the amazing PI @helenafricker🧊 and Deputy PI @ArmstonJohn 🌳 this would be the natural continuity of both @GEDI_Knights and @NASA_ICESat2
NASA has selected four proposals for concept studies of new @NASAClimate missions!
From studying greenhouse gases to global changes in ice and glaciers, each investigation will help gather the data needed to confront our changing climate and its impacts: go.nasa.gov/4b5ff3a

Big news for GEDI #biomass- new paper out describing the biomass models, AND version 2 of the associated product was recently released on @ORNLDAAC. The models described in this paper are in both the version 1 and 2 of the level 4A product. #OpenData @NASAEarthData
After several years of work, our paper describing @GEDI_Knights footprint-level (L4A) #biomass models of finally out! Massive thank you to the >100 co-authors who enabled this effort, esp. co-leads @ArmstonJohn @jamesrkellner sciencedirect.com/science/ar… @umdgeography @NASAEarth
