For the first time, scientists have obtained direct, quantifiable observations of cloud seeding for increased snowfall -- from the growth of ice crystals, through the processes that occur in clouds, t...
A new CU Boulder study comparing dissolved black carbon deposition on ice and snow in ecosystems around the world (including Antarctica, the Arctic and alpine regions of the Himalayas, Rockies, Andes ...
Can cloud seeding -- dispersing particles into the air with the aim of increasing precipitation -- increase snowfall? This week, a team of researchers began a cloud-seeding project in southwestern Ida...
SPRING SNOW A NO-GO?     SPRING SNOW  NO-GO       2016/6/12
Spring snowpack, relied on by ski resorts and water managers throughout the Western United States, may be more vulnerable to a warming climate in coming decades, according to a new University of Utah ...
Many factors related to warming will conspire to raise the planet’s oceans over coming decades — thermal expansion of the world’s oceans, melting of snow and ice worldwide, and the collapse of massive...
Snow -- that icon of winter -- blankets the land with a beautiful silence. Love it or hate it, we all depend on snow. Our year-round water supply largely comes from snowmelt.But we're not the only one...
For millennia, Greenland's ice sheet reflected sunlight back into space, but satellite measurements in recent years suggest the bright surface is darkening, causing solar heat to be absorbed and surfa...
Absorption of radiation by ice is extremely weak at visible and near-ultraviolet wavelengths, so small amounts of light-absorbing impurities in snow can dominate the absorption of solar radiation at t...
Two data sets consisting of measurements of light absorbing aerosols (LAA) in arctic snow together with suites of other corresponding chemical constituents are presented; the first from Siberia, Green...
Measurements of gas phase soluble bromide in the boundary layer and in firn air, and Br− in aerosol and snow, were made at Summit, Greenland (72.5° N, 38.4° W, 3200 m a.s.l.) as part of a larger...
In the last two decades, significant depletion of boundary layer ozone (ozone depletion events, ODEs) has been observed in both Arctic and Antarctic spring. ODEs are attributed to catalytic destructio...
Modeling studies show that the darkening of snow and ice by black carbon deposition is a major factor for the rapid disappearance of arctic sea ice, mountain glaciers and snow packs. This study provid...
The possible minimal range of reduction in snow surface albedo due to dry deposition of black carbon (BC) in the pre-monsoon period (March–May) was estimated as a lower bound together with the estimat...
The spring 2008 Arctic Research of the Composition of the Troposphere from Aircraft and Satellites (ARCTAS) experiment was one of major intensive field campaigns of the International Polar Year aimed ...
High-accuracy measurements of snow Bidirectional Reflectance Distribution Function (BRDF) were performed for four natural snow samples with a spectrogonio-radiometer in the 500–2600 nm wavelength rang...
