Journal ArticleDOI
Global Scale Attribution of Anthropogenic and Natural Dust Sources and their Emission Rates Based on MODIS Deep Blue Aerosol Products
TL;DR: In this article, a global-scale high-resolution (0.1°) mapping of sources based on Moderate Resolution Imaging Spectroradiometer (MODIS) Deep Blue estimates of dust optical depth in conjunction with other data sets including land use is presented.
Journal ArticleDOI
Global Estimates of Fine Particulate Matter Using a Combined Geophysical-Statistical Method with Information from Satellites, Models, and Monitors

TL;DR: This approach demonstrates that the addition of even sparse ground-based measurements to more globally continuous PM2.5 data sources can yield valuable improvements to PM 2.5 characterization on a global scale.
Journal ArticleDOI

Martin,Randall V. Martin +26 more
TL;DR: Global estimates of annual PM2.5 concentrations and trends for 1998-2018 are developed using advances in satellite observations, chemical transport modeling, and ground-based monitoring, identifying significant trends for eastern North America, Europe, and globally.
Journal ArticleDOI
Premonsoon aerosol characterization and radiative effects over the Indo‐Gangetic Plains: Implications for regional climate warming
TL;DR: In this paper, a detailed characterization of aerosols over the Indo-Gangetic Plains (IGP) and their radiative effects during the pre-monsoon season (April-May-June) was presented, using ground radiometric and spaceborne observations.
Journal ArticleDOI
Two contrasting dust‐dominant periods over India observed from MODIS and CALIPSO data
TL;DR: In this article, the authors integrated observations from space-borne sensors, namely MODIS and CALIPSO, together with ground sunphotometer measurements, to infer dust loading in the pre-monsoon aerosol build-up over source and sink regions in northern India.
