Aerosols are critical for “nowcasting” climate
Monthly Global Estimates of Fine Particulate Matter and Their Uncertainty
estimates provide precise regional-scale representation, with residual uncertainty inversely proportional to the sample size.
Global Estimates and Long-Term Trends of Fine Particulate Matter Concentrations (1998–2018)
/yr) for China over 2011-2018 are remarkable, with implications for the health of billions of people.
Global Estimates of Fine Particulate Matter using a Combined Geophysical-Statistical Method with Information from Satellites, Models, and Monitors
We estimated global fine particulate matter (PM2.5) concentrations using information from satellite-, simulation- and monitor-based sources by applying a Geographically Weighted Regression (GWR) to global geophysically based satellite-derived PM2.5 estimates. Aerosol optical depth from multiple satellite products (MISR, MODIS Dark Target, MODIS and SeaWiFS Deep Blue, and MODIS MAIAC) was combined with simulation (GEOS-Chem) based upon their relat…
Global Estimates of Ambient Fine Particulate Matter Concentrations from Satellite-Based Aerosol Optical Depth: Development and Application
BACKGROUND: Epidemiologic and health impact studies of fine particulate matter with diameter < 2.5 microm (PM2.5) are limited by the lack of monitoring data, especially in developing countries. Satellite observations offer valuable global information about PM2.5 concentrations. OBJECTIVE: In this study, we developed a technique for estimating surface PM2.5 concentrations from satellite observations. METHODS: We mapped global ground-level PM2.5 co…
An Overview of Terra Mission Results Related to the Carbon Cycle
Launched in December 1999 as the Earth Observing System's flagship observatory, the Terra Mission (formerly EOS AM-1) carries a suite of five instruments that collect comprehensive global measurements of earth's atmosphere, cryosphere, lands, and oceans. One of the mission's science goals is the collection of data that will enable a better quantitative understanding of earth's carbon cycle through direct observation of atmospheric constituents an…
