Women's History Month: A conversation with Dr. Lucy Hutyra

In honor of Women's History Month, NOAA is highlighting a few of its female scientists and funded researchers who are making significant strides in the climate sciences and other science fields. The following interview is with Dr. Lucy Hutyra, an Associate Professor in the Department of Earth and Environment at Boston University and CPO Atmospheric Chemistry, Carbon Cycle and Climate (AC4) Program-funded scientist.

AC4 Program holds inaugural PI meeting for Atmospheric Composition from Space Working Group

The principal investigator meeting was an opportunity to complement the atmospheric composition sessions at the JPSS/GOES-R Summit, and continue AC4 efforts to leverage existing meetings to hold principal investigator meetings.

New research provides unprecedented synthesis of how ozone is removed at Earth’s surface 25 February 2020

New research provides unprecedented synthesis of how ozone is removed at Earth’s surface

Better understanding of how ozone, an air pollutant and greenhouse gas, is removed is essential for improved modeling and prediction of air pollution, ecosystem health, and climate.

Just published: Methane emissions from regional oil and gas production can be observed from space 4 February 2020

Just published: Methane emissions from regional oil and gas production can be observed from space

Methane is the second most important anthropogenic greenhouse gas in the atmosphere after carbon dioxide, with U.S. oil and natural gas supply chain methane emissions, in particular, making up about 41% of anthropogenic emissions in the United States.

Stratospheric variability influences emissions levels at Earth’s surface, study says 7 January 2020

Stratospheric variability influences emissions levels at Earth’s surface, study says

The new research in Nature Geoscience suggests that global budget estimates of ozone-depleting substances as well as other trace gases like methane could be improved by accounting for the Quasi-Biennial Oscillation’s influence.
