Comparing the performance of atmospheric transport models to real-life measurements helps researchers isolate problem areas and produce more accurate urban air pollution and greenhouse gas (GHG) emission estimates.

Dust emissions at open-cut coal mines are a potential threat to air quality in surrounding areas. To learn more about particulate matter (PM) and how it travels beyond a mine’s boundaries, a research grant from the Australian Coal Association Research Program (ACARP) was awarded to Pacific Environment, an environmental consulting firm based in Sydney, Australia. […]

From June to October, the burning of agricultural fields in southern Africa creates smoke that blows west across the southeastern Atlantic Ocean and reaches Brazil, over 4,500 miles away. Using Micro Pulse LiDAR (MPL) and other instruments, researchers at the Atmospheric Radiation Measurement (ARM) user facility on the remote island of Ascension, operated by the […]

Poor air quality in large urban population centers has a negative impact on health and quality of life. To address these issues, the Institute of Urban Meteorology (IUM) in Beijing, China, is conducting fundamental research to better understand, forecast and mitigate atmospheric haze, i.e., air pollution. Over the past two years, IUM has studied the […]

Public health problems related to airborne pollen activity are on the rise in European megacities. Many people suffer from allergic reactions to biogenic particles that are naturally created by trees, grasses, flowers and other vegetation. Cities with large parks and gardens or nearby forests tend to have higher pollen counts than less green urban areas. […]

A Micro Pulse LiDAR (MPL) system at South Florida’s Cloud-Aerosol-Rain Observatory (CAROb) collected data to further research on the effects of low clouds and dust on the climate.
