NASA’s Goddard Institute for Space Studies (GISS) in New York, which monitors global surface temperatures on an ongoing basis, released an updated analysis that shows temperatures around the globe in 2011 compared to the average global temperature from the mid-20th century. The comparison shows how Earth continues to experience warmer temperatures than several decades ago.

NASA scientists have successfully completed flight tests in preparation for deployment of a multi-year airborne science campaign to study the humidity and chemical composition of air entering the tropical tropopause layer of the atmosphere. NASA’s Airborne Tropical TRopopause EXperiment (ATTREX) will conduct the science campaign over the Pacific Ocean from three locations in 2013 and

NASA’s airborne expedition over Antarctica this October and November has measured the change in glaciers vital to sea level rise projections and mapped others rarely traversed by humans. Operation IceBridge, nearing completion of its third year, is the largest airborne campaign ever flown over the world’s polar regions. Bridging a gap between two ice elevation

Part of human fascination with space is the chance to look back at our own planet from afar. The unique vantage from the International Space Station affords a vista both breathtaking and scientifically illuminating. Here on Earth, both scientists and spectators rely on the station’s crew to record and transmit images and videos of what

During a visit to South America, NASA Administrator Charles Bolden Thursday signed two cooperative Earth science agreements with Agencia Espacial Brasileira (AEB), NASA’s counterpart space agency in Brazil. One agreement formalizes NASA-AEB scientific collaboration on the Global Precipitation Measurement, or GPM, mission, while the other extends an agreement for the Ozone Cooperation Mission.

Scientists with NASA’s Operation IceBridge airborne research campaign began the mission’s third year of surveys this week over the changing ice of Antarctica. Researchers are flying a suite of scientific instruments on two planes from a base of operations in Punta Arenas, Chile: a DC-8 operated by NASA and a Gulfstream V (G-V) operated by

NASA and Japan released a significantly improved version of the most complete digital topographic map of Earth on Monday, produced with detailed measurements from NASA’s Terra spacecraft. The map, known as a global digital elevation model, was created from images collected by the Japanese Advanced Spaceborne Thermal Emission and Reflection Radiometer, or ASTER, instrument aboard

NASA is planning an Oct. 27 launch of the first Earth-observing satellite to measure both global climate changes and key weather variables. The National Polar-orbiting Operational Environmental Satellite System Preparatory Project (NPP) is the first mission designed to collect critical data to improve weather forecasts in the short-term and increase our understanding of long-term climate

A NASA-led study has documented an unprecedented depletion of Earth’s protective ozone layer above the Arctic last winter and spring caused by an unusually prolonged period of extremely low temperatures in the stratosphere. The study, published online Sunday, Oct. 2, in the journal Nature, finds the amount of ozone destroyed in the Arctic in 2011
