New Algorithm Vastly Improves Measurements of SO2 Pollution from Space

New Algorithm Vastly Improves Measurements of SO2 Pollution from Space

Sulfur dioxide (SO2), emitted from both man-made and volcanic activities, significantly impact air quality and climate. Advanced sensors including the Ozone Monitoring Instrument (OMI) have been employed to measure SO2 pollution.

NASA Satellite Sees Increase of India's Sulfur Dioxide Emissions

NASA Satellite Sees Increase of India's Sulfur Dioxide Emissions

The analysis of data captured by the Ozone Monitoring Instrument (OMI) found that emissions of sulfur dioxide from Indian power plants have increased by more than 60 percent between 2005 and 2012

A Deep Ozone Hole in Spite of Low Chlorine: How Transport Affects Chemistry

MLS ClO in the 2011 Antarctic vortex was 20% lower than 2006, yet the 2011 ozone hole is very similar to the 2006 hole, the largest ever observed.

Homogenizing Global Sulfur Dioxide Measurements from Multiple Satellite Sensors

Satellite mapping of sulfur dioxide (SO2) is useful to track volcanic and anthropogenic emissions in places where detailed SO2 emission information is not available.

TES measurements demonstrate ammonia emissions are under-reported

TES measurements demonstrate ammonia emissions are under-reported

Ammonia (NH3) pungently affects air quality. It is also involved in the formation of aerosol PM2.5 particles, which have adverse health effects, and impacts soil acidification, biodiversity, and the nitrogen cycle.
