Contributions of clouds, surface albedos, and mixed-phase ice nucleation...
The Arctic radiation balance is strongly affected by clouds and surface albedo. Prior work has identified Arctic cloud liquid water path (LWP) and surface radiative flux biases...- publication PDF

Permafrost carbon-climate feedback is sensitive to deep soil carbon...
Permafrost soils contain enormous amounts of organic carbon whose stability is contingent on remaining frozen. With future warming, these soils may release carbon to the...- publication PDF

Externally forced and internally generated decadal climate variability...
Globally averaged surface air temperatures in some decades show rapid increases (accelerated warming decades), and in other decades there is no warming trend (hiatus decades). A...- publication PDF

Adjustments for wind-induced undercatch in snowfall measurements based on...
Adjustments for the wind-induced undercatch of snowfall measurements use transfer functions to account for the expected reduction of the collection efficiency with increasing...- publication PDF

Uncertainties in climate responses to past land cover change: First results...
Seven climate models were used to explore the biogeophysical impacts of human-induced land cover change (LCC) at regional and global scales. The imposed LCC led to statistically...- publication PDF

Chemical composition of atmospheric nanoparticles during nucleation events in Atlanta
We report the first direct, in situ measurements of the chemical composition of size-segregated atmospheric nanoparticles in the 6 - 15 nm diameter range. These measurements...- publication PDF
