Results of three carbon stock estimation approaches for the Louisiana Delta region: Left, using independently generated soil carbon maps from SSURGO; Middle, using the SSURGO bias-corrected for bulk density; Right, using single average carbon stock value from the compiled soil core data.

Body

Soil carbon stocks for tidal wetland areas of the United States were estimated using four modeling approaches.

Circles mark the locations of the 139 selected profiles sampling the remote troposphere. Circle color indicates HCHO column densities integrated over each ATom profile. Data are overlain on global gridded OMI HCHO column densities averaged over the mission. From Wolfe et al. (2019) (see dataset references).

Body

New data from NASA's Atmospheric Tomography Mission (ATom) provide hydroxyl and formaldehyde column density in the remote troposphere.

Arctic biweekly NDVI (green bars) and trend (grey bars) for full tundra for 1999-2015. Biweekly trends statistically significant at the 95% level or greater are marked with an asterisk on the x-axis. From Figure 9 (c) Bhatt et al. (2017) (see dataset documentation).

Body

NASA's ABoVE provides standardized data on potential climate drivers for productivity of Arctic tundra vegetation.
