Global distribution of mangrove loss and its drivers. (a) The longitudinal distribution of total mangrove loss and the relative contribution of its primary drivers. Different colors represent unique drivers of mangrove loss. (b) The latitudinal distribution of total mangrove loss and the relative contribution of its primary drivers. (c-g) Global distribution of mangrove loss and associated drivers from 2000 to 2016 at 1-degree x 1-degree resolution, with the relative contribution (percentage) of primary drivers per continent: (c) North America, (d) South America, (e) Africa, (f) Asia, (g) Australia together with Oceania.

Body
Estimates of mangrove loss, land cover change, and its anthropogenic or climatic drivers 2000-2005, 2005-2010, and 2010-2016.

Caption

Curtain plot for production of ozone from the ATom-1 campaign in the Atlantic. The 10 s air parcels are averaged into 10-degree latitude and 200 m altitude bins. Reactivities, such as P-O3, are calculated for each 10 s air parcel from the Modeling Data Stream (MDS), Version 2, using the UC Irvine chemistry-transport model (CTM) with HNO4 and PAN damped by thermal decomposition.

Body
Modeling Data Stream (MDS) and Reactivity Data Stream (RDS) products for each of the four ATom campaigns conducted from 2016 to 2018.

Map of measurement stations in the Boston network. The black line demarcates the 90 km radius circle in which emissions were optimized and the dashed line bounds the urban domain for study. The blue shading represents the number of housing units with natural gas per square kilometer. The red and blue contour encloses 50% of the average footprint initiated at the COP and BU sites, respectively.

Body
Hourly average atmospheric measurements of CH4 from multiple sites in and around Boston, MA. from September 2012-May 2020
