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.

ABGB outputs over CONUS derived from CARDAMOM vs. the CMS project-funded ABGB estimated from inventory and satellite data (Yu et al., 2021). The left panel shows the colormaps of differences between ABGB from CARDAMOM and ABGB from CMS for the years 2005, 2010, and 2015. The right panel is the scatter plot showing the pixel-level ABGB deviations from the 1:1 line for CARDAMOM- and CMS-derived outputs.

Body
16 years of carbon pools and fluxes estimated from CARDAMOM for the contiguous USA at 0.5-degree resolution recently published.
