Epidemiologic Opportunities: How Satellite Data Contribute to Studies of Air Pollution and Human Health

摘要

1.Air pollution: main environmental risk factor for health 2.～3.7 million deaths in 2012 from outdoor air pollution globally 2.1 80% due to cardiovascular and cerebrovascular diseases 2.2Majority of impacts in low and middle income countries 3.PM_(2.5) is the largest contributor At Mount Sinai, we use NASA satellite data to reconstruct fine particulate pollution (PM_(2.5)) Aerosol Optical Depth (AOD) estimates light extinction by aerosol scattering/absorption in the atmospheric column 1.Daily models generate billions of predictions 2.Using machine-learning algorithms to make our models flexible and scalable 3.But great care is needed to avoid overfitting 627,255 grid cells 229 million predictions annually Our temperature and air pollution models to be used in a study of ＞50,000 children across the USA to look for links with rare health outcomes.
