A new, low-cost cubesat mission led by the Johns Hopkins Applied Physics Laboratory in Laurel, Md., will demonstrate technology needed to measure the absolute imbalance in the Earth's radiation budget for the first time, giving scientists valuable information to study our climate.
Clouds can both warm and cool Earth's atmosphere. In current climate models, detailed conditions for cloud cover as a climatic factor are still not clearly understood. There is a shortage of precise measurements on how the water, humidity, ice particles and aerosols that form water droplets are distributed in towering cumulus clouds.

Three years of observations by ESA's CryoSat satellite show that the West Antarctic Ice Sheet is losing over 150 cubic kilometres of ice each year - considerably more than when last surveyed.

Human activities, a changing climate and natural disasters are rapidly altering the face of our planet. Now, with NASA's Images of Change iPad application, users can get an interactive before-and-after view of these changes.

ESA's GOCE satellite has revealed that the devastating Japanese earthquake of 2011 left its mark in Earth's gravity - yet another example of this extraordinary mission surpassing its original scope.

Between 3.5 and 4.5 million square kilometres of land surface are burnt every year. More than half of this burnt surface is in Africa, which has more than 6000 protected areas across 50 countries.

Scientists have used satellite observations to create a set of high-resolution 3D maps of the entire Great Barrier Reef - a critical step towards identifying, managing and protecting what lies beneath the waters.
With current Earth observation technologies and satellites, it is possible to target specific ecosystems or at-risk regions that have become vulnerable to air and water quality problems as a result of climate change. That was the conclusion of Climatologist DeWayne Cecil, PhD in a resent White Paper for a study team sponsored by Sharon Kleyne's Bio-Logic Aqua Research. The White Paper suggests a series of steps to implement programs that define and solve water and air problems on a regional or local level.

German and Australian scientists today launched a set of groundbreaking, high resolution, shallow water topography maps for the entire Great Barrier Reef. These world-first digital maps of the coral reefs, using satellite derived depth (bathymetry) techniques, are a critical step towards identifying, managing and essentially preserving and protecting what lies within the waters of this global icon.

A new study based on Earth-observing satellite data comprehensively describes changes in the world's forests from the beginning of this century. Published in Science today, this unparalleled survey of global forests tracked forest loss and gain at the spatial granularity of an area covered by a baseball diamond (30-metre resolution).

A new, space-based map generated by scientists at NASA's Jet Propulsion Laboratory, Pasadena, Calif., in collaboration with the Italian Space Agency to assist in disaster response efforts shows the regions in the Philippines hit hardest by Super Typhoon Haiyan. The typhoon tore a wide swath of devastation across the island nation on 08 November 2013.

Two scientists from NASA and NOAA have developed a new space-based technique for monitoring the ice cover of the Great Lakes that is so accurate it can identify a narrow channel of open water cut through the ice by an icebreaker -- even at night.

More than 700 residential buildings were completely destroyed and more than 1200 were damaged by the Haiyan typhoon in the Tacloban city alone (Philippines).

International experts agree that Cyclone Haiyan, which hit the Philippines on 9 November, was "probably the most intense and strongest storm of this type to make landfall". While cyclones of this intensity have occurred before, they usually lose part of their strength by the time they reach shore. Not Haiyan, which swept through six central Philippine islands packing winds of up to 270 Km/h and causing immense damage and probably unprecedented loss of life.

New satellite images just obtained from NASA's Atmospheric Infrared Sounder (AIRS) instrument aboard NASA's Aqua spacecraft and the Indian Space Research Organization's OceanSAT-2 ocean wind scatterometer provide a glimpse into one of the most powerful storms ever recorded on Earth.

NOAA unveiled, on 05 November, the beta version of "NOAA View," an online educational tool that gives educators and the public interactive access to NOAA environmental data, enabling unique views of the world's oceans, land, atmosphere, cryosphere and climate.

JRC scientists obtained remarkable results in correcting surface shapes of satellite imagery to study mountainous terrains, with a combination of topographic correction algorithms and statistical methods. The JRC presented its new method in a recently published article in the IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing.

In just five years, the partnership between the World Bank and the European Space Agency has shown that Earth observation is a critical - and some would argue, indispensable - tool in international development.
For the first time, a NASA airborne campaign will measure changes in the height of the Greenland Ice Sheet and surrounding Arctic sea ice produced by a single season of summer melt.
