NOAA-led study: Colorado oil and gas wells emit more pollutants than expected

NOAA-led study: Colorado oil and gas wells emit more pollutants than expected

When NOAA scientists began routinely monitoring the atmosphere’s composition at a tower north of Denver a few years ago, their instruments immediately sniffed something strange: plumes of air rich with chemical pollutants including the potent greenhouse gas methane.

Utah’s winter air quality mystery

Utah’s winter air quality mystery

During the last two winters, air quality monitors near oil and gas fields in the Uintah Basin have picked up episodes of ozone pollution far in excess of federal health-based standards in the least likely time -- during winter.

Chemical measurements confirm official estimate of Gulf oil spill rate

Chemical measurements confirm official estimate of Gulf oil spill rate

By combining detailed chemical measurements in the deep ocean, in the oil slick, and in the air, NOAA scientists and academic colleagues have independently estimated how fast gases and oil were leaking during the 2010 Deepwater Horizon oil spill in the Gulf of Mexico.

Air pollution levels from Deepwater Horizon spill similar to large urban area

The amount of air pollutants in the atmospheric plume generated by the Deepwater Horizon oil spill was similar to a large city according to a new NOAA-led study published today in a special issue of Proceedings of the National Academy of Sciences.
