As air quality in the Eastern United States has improved, determining the root cause of air pollution episodes has become more challenging. This not only impacts the ability to reliably forecast pollution episodes but also the development of regulations that will lead to further reductions in ozone and its precursors, such as NOxand volatile organic compounds (VOCs).

Passive aerosol sensors composing the present generation of space-based instrumentation generally permit measurements spanning the majority of the shortwave spectrum, or observations at multiple viewing angles, but rarely both. Moreover, very few of these instruments possess sensitivity to polarization, and those that do lack the accuracy required to fully utilize this quantity.

Goddard Space Flight Center airborne campaigns are highlighted in a recent Capital Weather Gang article in The Washington Post. The article describes the novel coronavirus's impact on scientific research and field campaigns.

NASA’s new 3D picture of methane concentrations shows the second-largest contributor to greenhouse warming and its behavior throughout the atmosphere.

After nearly two decades, the Sun has set for NASA’s SOlar Radiation and Climate Experiment (SORCE), a mission that continued and advanced the agency’s 40-year record of measuring solar irradiance and studying its influence on Earth’s climate.

NASA’s Terra satellite passed over the Southern Pacific Ocean and captured an image of Tropical Storm Gretel as it was transitioning into an extra-tropical cyclone, northwest of New Zealand.

Ryan Stauffer (614/UMD) was featured in The Washington Post Capital Weather Gang story on the thick smoke observed in the DC and Baltimore region on March 8, 2020. Smoke from a controlled burn near Quantico, Virginia, drifted into DC midday and into Baltimore by late evening Sunday, and led to particulate pollution and poor air quality at the surface.

Constraining how much the Earth’s climate will warm in response to greenhouse gas emissions is one of the primary goals of climate science. Our understanding of clouds and their interactions with their environment represent a central uncertainty in constraining climate sensitivity.

Radiative forcing is the radiative perturbation caused by a change in atmospheric composition from which all other climate changes stem. Although a fundamental metric in climate science, it has not always been clearly defined.

In the era of information big-bang, we can easily get overwhelmed or “take a ride on the wild side”.
