An intercomparison of total column-averaged nitrous oxide between ground-base...
Nitrous oxide (N2O) is an important greenhouse gas and it can also generate nitric oxide, which depletes ozone in the stratosphere. It is a common target species of ground-based...- publication PDF

COVID‐19 crisis reduces free tropospheric ozone across the Northern Hemisphere
Throughout spring and summer 2020, ozone stations in the northern extratropics recorded unusually low ozone in the free troposphere. From April to August, and from 1 to 8...- publication PDF

Centennial-scale climate change from decadally-paced explosive volcanism: A c...
Northern Hemisphere summer cooling through the Holocene is largely driven by the steady decrease in summer insolation tied to the precession of the equinoxes. However,...- publication PDF

Characterization and potential for reducing optical resonances in Fourier tra...
Although optical components in Fourier transform infrared (FTIR) spectrometers are preferably wedged, in practice, infrared spectra typically suffer from the effects of optical...- publication PDF

Climate response to large, high-latitude and low-latitude volcanic eruptions ...
Explosive volcanism is known to be a leading natural cause of climate change. The second half of the 13th century was likely the most volcanically perturbed half-century of the...- publication PDF

Comparing the impacts of tropical SST variability and Polar stratospheric ozo...
Westerly wind trends at 850 hPa over the Southern Ocean during 1979-2011 exhibit strong regional and seasonal asymmetries. On an annual basis, trends in the Pacific sector...- publication PDF
