The MODIS/ASTER Airborne Simulator (MASTER) facility instrument is maintained and operated by the Airborne Sensor Facility at NASA Ames Research Center under the oversight of the EOS Project Office at NASA GSFC.
Two datasets containing Level 1B and Level 2 data products from the MASTER instrument recently published.
Absorbed dose rate in silicon (top panel) and the 3D representation of the flight (bottom panel). The colored region above 20 km is the notional hazards of the incoming particle environment at the top of the atmosphere, where red indicates greater hazard (more particle flux) at the high latitudes while green represents lower hazard (lower particle flux and lower radiation exposure) in the equatorial region.
Level 2 absorbed radiation dose rates in silicon from the Automated Radiation Measurements for Aerospace Safety (ARMAS) system.

Landsat based annual time series and season trend for lakes across the ABoVE Extended Study Domain, 1984 to 2019 recently published.
Overview of the assimilation system (CLM5-DART) that combines observations with model ensemble simulations from CLM5.0. Satellite-derived observations of aboveground biomass and leaf area index were used to adjust the simulated model state of CLM5.0. Source: Razcka et al. (2021)
Monthly estimates of biomass stocks and land-atmosphere carbon exchange across the western United States available.
Example subset of aboveground biomass density (AGBD; Mg ha-1) predictions from the GEDI Level-4A footprint version 2.1 product over Northern California, USA, spanning April to July 2019. GEDI footprints are spaced 60m along track and 600m across-track.
Jupyter Notebook tutorials are available to demonstrate searching and downloading the GEDI L4a dataset and subsetting the GEDI L4A footprints.
