Earth’s clouds may be getting lower

An analysis of MISR measurements of cloud height over the past decade show a slight drop in cloud height. Between March 2000 and February 2010, global cloud height dropped by one percent on average. Read more.

NASA map sees Earth’s trees in a new light

A NASA-led science team has created an accurate, high-resolution map of the height of Earth’s forests. The map will help scientists better understand the role forests play in climate change and how their heights influence wildlife habitats within them, while also helping them quantify the carbon stored in Earth’s vegetation.

NASA’s newest CERES instrument begins collecting data

Terra’s CERES sensor is one in a series of instruments that measure Earth’s energy balance. On January 27, the newest version of the Clouds and the Earth’s Radiant Energy System (CERES) instrument on the Suomi National Polar-orbiting Partnership (NPP) began scanning Earth for the first time, helping to assure continued availability of measurements of the energy leaving the Earth-atmosphere system.
