Radar Imaging Could Be the Key to Monitoring Climate Change

Cars That Think

Moreira’s technology also helps to track the effects of climate change. In September 2016 the first global digital elevation map with a 2-meter height accuracy was produced. He worked in that position until 2001, when he became director of the Microwaves and Radar Institute. “I I selected the right profession,” he says.

Scientists call for careful use of time scales, reference dates and statistical approaches in analyzing climate change trends to avoid distortion and hampering of response

Green Car Congress

Demonstrating that the use of different time scales, reference dates, and statistical approaches can generate highly disparate results in climate reports, scientists at the University of Alaska Anchorage argue that careful use of these tools is critical for correctly interpreting and reporting climatic trends in Alaska and other polar regions.

Peking University team develops method for modeling historical global black carbon emissions from motor vehicles with reduced uncertainty

Green Car Congress

Geographical distributions of global BC emissions from motor vehicles in 1976 (A) and 2006 (B). In addition to a reduction in uncertainty, their new model can be used to develop a global on-road vehicle BC emission inventory with spatial and temporal resolution, the researchers suggest.
