In a potential boon for agriculture, a NASA-funded effort that involves NCAR and the private firm DTN/Meteorlogix has produced one of the world’s most accurate systems for predicting soil temperature up to two days in advance.

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.
