DEM of the Global Change Research Wetland (GCReW) site generated using the LEAN (LiDAR Elevation Correction with NDVI) method. LEAN uses ground measurements of elevation and NDVI in a multivariate linear regression model to estimate vertical bias.
Four digital elevation models (DEMs) at 1-m resolution and 2106 model performance metrics for the GCReW site, Maryland, USA are now available.
Arctic-CAP flights consisted of vertical profile maneuvers from near the surface to 6 km altitude around the ABoVE domain each month. Profiles were flown at each of the 25 locations listed across the top of this figure.
Atmospheric gas concentrations collected during the Arctic Carbon Aircraft Profile (Arctic-CAP) campaigns are now available.
Spatial distribution of mean dissolved inorganic carbon (DIC) leaching (g c/m2/yr) in the 2090s estimated by S(ALL) simulation experiment (including future climate, elevated CO2, and land use changes). Climate change scenarios were derived from three climate models named CCSM3 (panels a and b), ECHAM (c and d), and CCCMA (e and f) under high (A2) and low (B1) emission scenarios, respectively.
New data from the Carbon Monitoring System (CMS) offers insights into how environmental factors affect the dynamics of leaching.
Generalized overview of ATom flights. During each of the four campaigns, ATom flights originated from California, flew south over the Pacific Ocean, then north to the western Arctic, southwest to New Zealand, east to Chile and the Atlantic Ocean, north to Greenland, and returned to California across North America. During flights, the aircraft continuously profiled the atmosphere from 0.2 to 12 km altitude.
The Atmospheric Tomography Mission (ATom) has released multi-instrument merged data from all four flight campaigns spanning from 2016 - 2018.
