On the enigmatic similarity in Greenland δ¹⁸O between the Oldest and Younger Dryas
The last deglaciation (20.0-10.0 kyr B.P.) was punctuated by two major cooling events affecting the Northern Hemisphere: the Oldest Dryas (OD; 18.0-14.7 kyr B.P.) and the...- publication PDF

Does organization in turbulence influence ozone removal by deciduous forests?
Dry deposition is an important sink of tropospheric ozone and influences background and episodic ozone air pollution. Plant canopies remove ozone through uptake by plant...- publication PDF

Impact of grain shape and multiple black carbon internal mixing on snow...
We quantify the effects of grain shape and multiple black carbon (BC)-snow internal mixing on snow albedo by explicitly resolving shape and mixing structures. Nonspherical snow...- publication PDF
