Research from MIRAGE (Megacities Impacts on Regional and Global Environments), a field campaign held in Mexico City in 2006, is coming to fruition as scientists begin to publish their findings. A new paper details the ozone “weekend effect” in Mexico City and its implications for local air pollution.

NCAR scientist Brian O’Neill is building an integrated assessment model to link a range of societal factors, such as future global economic and population trends, with the physical science of climate change.

Research by NCAR scientist Mary Hayden underscores the risk of dengue fever and the growing threat of dengue hemorrhagic fever in the Rio Grande Valley between far south Texas and northeast Mexico.

NCAR scientists Bill Large and Steve Yeager have produced a new analysis of the exchanges of heat, momentum, and moisture between the oceans and atmosphere that should help climate modelers better assess variability on several time scales.

Mountain pine beetles appear to be doing more than killing large swaths of forests in the Rocky Mountains. Scientists suspect they are also altering local weather patterns and air quality.
