Modeling regional aerosol variability over California and its sensitivity to emissions and long-range transport during the 2010 CalNex and CARES campaigns

AC4 News, Climate.gov RSS, General News / By

A new paper: “Modeling regional aerosol variability over California and its sensitivity to emissions and long-range transport during the 2010 CalNex and CARES campaigns,” has been published in the Journal for Atmospheric Chemistry and Physics. CalNex (the California Nexus, Research at the Nexus of Air Quality and Climate Change) is a 2010 field program funded by state of California and the Climate Program Office’s Atmospheric Chemistry, Carbon Cycle, & Climate (AC4) program.

Airborne measurements confirm leaks from oil and gas operations

AC4 News, Atmospheric Chemistry, Carbon Cycle and Climate (AC4), Climate.gov RSS, General News / By

During two days of intensive airborne measurements, oil and gas operations in Colorado’s Front Range leaked nearly three times as much methane, a greenhouse gas, as predicted based on inventory estimates, and seven times as much benzene, a regulated air toxic.
