New NASA research shows that by releasing heat and moisture through a large hole in sea ice known as a polynya, the exposed ocean fuels the formation of more clouds that trap heat in the atmosphere and hinder the refreezing of new sea ice.

Smoke from several large wildfires burning in Northern California can be seen traveling miles into the atmosphere.

15 years of MISR data show air pollution controls working in Southern California

New evidence shows that California’s clean air programs that reduce particle pollution in California are working.

Scientists from Emory University, NASA’s Jet Propulsion Laboratory, and the California Air Resources Board analyzed the 15-year trend of fine particle pollution based on satellite data from Terra’s Multi-angle Imaging SpectroRadiometer (MISR) instrument. This type of pollution, known as PM2.5 (less than 2.5 microns in diameter) accounts for the greatest percentage of health impacts attributable to air pollution in California.

The study was recently published in the journal “Atmospheric Environment” is the first to evaluate long-term changes in major PM2.5 components using spatially comprehensive satellite data, according the the California Air Resources Board.
