  • GEDI finished its on-orbit checkout phase (the commissioning period) and started official operations to acquire science data on March 25th, 2019. GEDI is currently following Reference Ground Tracks (RGTs) to evenly sample the forest structure across the earth. Every week the science team prioritizes the potential RGTs by programming the instrument to point nadir, or slightly off-nadir, to provide the best spatial coverage and to target specific areas of interest. The science data collection phase is scheduled to last for 2 years and the first data products will be delivered in six months around the end of September, 2019. Before then we plan to make example data sets available to help the community prepare for the first data release.
