Volcanoes’ Future Climate Effects May Exceed Standard Estimates
Future releases of sulfur dioxide from volcanoes will likely be higher than the reconstructed historical levels currently used for climate predictions.
Sea Ice Is Going, but When Will It Be Gone?
A pair of studies demonstrate the uncertainty over when the Arctic will become seasonally sea ice free.
Tracking Human CO2 Emissions from Medium-Sized Cities
Atmospheric inverse models, combined with observations, successfully tracked modest CO2 emission reductions in Salt Lake City during the first COVID-19 lockdown in 2020.
Simulating the Journey of Pollen in the Atmosphere
A new study couples an emission and transport scheme of pollen from vegetation, and explores pollen’s evolution in different atmospheric conditions and its impacts on clouds and precipitation.
The Nitty-Gritty Forces That Shape Planetary Surfaces
Scientists are coming up with ingenious ways to compare terrestrial sand dunes, dust storms, and rain with their counterparts on Mars and Titan.
A New Perspective on Aerosols and Emissions Over Northern China
During 2013-2019, a distinct seasonality for trends of aerosol concentrations and optical properties was found over Northern China.
Simulating Clouds on Arbitrary Grids in Any Spatial Direction
A new non-column based spectral element implementation of cloud microphysics enables full 3D flexibility in computing clouds and improves computational efficiency.
Modeling Whole Atmosphere Responses to the Hunga-Tonga Eruption
A high-resolution whole atmosphere simulation captures the strong, global responses up to the thermosphere and ionosphere following the Hunga-Tonga volcano eruption.
Reducing Aerosol Climate-Forcing Uncertainty: A Three-Way Street
To reduce persistent aerosol-climate-forcing uncertainty, new in situ aerosol and cloud measurement programs are needed, plus much better integration of satellite and suborbital measurements with models.
