Snow’s thermal and radiative properties strongly impact the land surface energy balance and thus the atmosphere above it. Land surface snow information is poorly known in mountainous regions. Few studies have examined the impact of initial land surface snow conditions in high-resolution, convection-permitting numerical weather prediction models during the midlatitude cool season. The extent to which land surface snow influences atmospheric energy transport and subsequent surface meteorological states is tested using a high-resolution (1 km) configuration of the Weather Research and Forecasting (WRF) Model, for both calm conditions and weather characteristic of a warm late March atmospheric river. A set …


Unveiling Assigned Amount Unit (Aau) Trades: Current Market Impacts And Prospects For The Future, Elizabeth Lokey Aldrich, Cassandra L. Koerner Mar 2012

Unveiling Assigned Amount Unit (Aau) Trades: Current Market Impacts And Prospects For The Future, Elizabeth Lokey Aldrich, Cassandra L. Koerner

CAES Energy Policy Institute Faculty Publications and Presentations

The sale of assigned amount units (AAUs) from countries whose emissions have declined since their baseline year under the Kyoto Protocol has led critics to be skeptical of carbon markets due to the lack of actual emission reductions that occur as a result of these trades. This policy review describes the historical context of AAU trading, current market price and volumes, and environmental and economic impacts of the current AAU trading rules. Options for how to handle current, and prevent the creation of future, surplus AAUs are discussed.
