✈️📦 Special delivery! The S-SAR (synthetic aperture radar) instrument just arrived at JPL for installation on the NISAR satellite. It's one of two radars on this joint NASA Earth-ISRO mission to help us study hazards and global environmental change. nisar.jpl.nasa.gov

It is with great pleasure that I announce our biomass protocol has been officially endorsed by CEOS! This NASA supported activity was a huge effort by >50 co-authors from many CEOS agencies. Official doc link here - please share widely! doi:10.5067/doc/ceoswgcv/lpv/agb.001

Big news for GEDI #biomass- new paper out describing the biomass models, AND version 2 of the associated product was recently released on ORNL DAAC. The models described in this paper are in both the version 1 and 2 of the level 4A product. #OpenData NASAEarthdata

NASA has selected four proposals for concept studies of new ARCHIVED - NASA Climate 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
