Investment boosts Space Station photography

22 September 2013

The nonprofit organisation managing research on the International Space Station has invested $300,000 to improve on-orbit photography. It's expected that The Center for the Advancement of Science in Space's investment also will enhance Earth images for scientific research and education.

Arctic sea ice minimum in 2013 is sixth lowest on record

20 September 2013

After an unusually cold summer in the northernmost latitudes, Arctic sea ice appears to have reached its annual minimum summer extent for 2013 on 13 September, the NASA-supported National Snow and Ice Data Center (NSIDC) at the University of Colorado in Boulder has reported.

Surveying fire and ice: First map of all of Iceland's glaciers and subglacier volcanic calderas released

19 September 2013

For the first time, all of Iceland's glaciers are shown on a single map, produced by the Icelandic Meteorological Office (IMO), in collaboration with the U. S. Geological Survey (USGS) and Iceland Geosurvey. The map is the first to incorporate historical data and coverage from aerial photographs and remote sensing satellites, such as Landsat and SPOT, to show the change in the areal extent of glaciers during the past century.

NASA supercomputer generates closer look at future climate conditions in U.S.

10 September 2013

Global models of the climate system are now the foundation for many important climate studies, but they typically show climate changes at very large geographic scales on the order of 100 to 250 kilometres. Some data sets have scaled that down to about 10 kilometres, but even these make it difficult to analyse climate change impacts on a local or regional scale.

Reflecting on Earth's albedo

06 September 2013

The amount of sunlight being absorbed or reflected by Earth is one of the driving forces for weather and climate. Satellites are providing this information with unprecedented accuracy.

Earth's 'carbon dioxide breathing' seen from space

04 September 2013

Ten years of satellite observations of greenhouse gases reveal that carbon dioxide in our atmosphere continues to increase despite international efforts to reduce carbon emissions. Satellites also show that recent methane increases are likely due to manmade emissions.

Arctic sea ice update: Unlikely to break records, but continuing downward trend

23 August 2013

The melting of sea ice in the Arctic is well on its way toward its annual "minimum," that time when the floating ice cap covers less of the Arctic Ocean than at any other period during the year. While the ice will continue to shrink until around mid-September, it is unlikely that this year's summer low will break a new record. Still, this year's melt rates are in line with the sustained decline of the Arctic ice cover observed by NASA and other satellites over the last several decades.

High above Earth, satellites direct ground-breaking development work

20 August 2013

When the World Bank first teamed up with the European Space Agency to demonstrate how Earth observation can work for international development, a small climate change adaptation project on the coast of North Africa produced the first big results.

A satellite view of the oceans

20 August 2013

Gazing down from space, satellites have the best view of ice floes drifting, waves swelling restlessly, currents moving dangerously, the spread of oil slicks and the changing positions of ships. For this reason, researchers at the German Aerospace Center (Deutsches Zentrum fur Luft- und Raumfahrt; DLR) analyse radar images or use satellites to receive ship signals. Now, DLR is pooling the research work conducted at its Remote Sensing Technology Institute and the Institute for Space Systems within the Research Centre for Maritime Safety in Bremen.

UNOSAT continues mapping effort as Sudan braces for more flooding

16 August 2013

After initial flooding that killed more than 50 people in the first week of August, Sudan's weather authorities have announced that heavy rain falling in Ethiopia is likely to cause additional flooding in Sudan. So far the floods affected 200,000 Sudanese, according to the Minister of Interior, and have prompted aid from Qatar, Egypt and Ethiopia.

Around the world in four days: NASA tracks Chelyabinsk meteor plume

14 August 2013

Atmospheric physicist Nick Gorkavyi missed witnessing an event of the century last winter when a meteor exploded over his hometown of Chelyabinsk, Russia. From Greenbelt, Md., however, NASA's Gorkavyi and colleagues witnessed a never-before-seen view of the atmospheric aftermath of the explosion.

Earth is breathing deeper

08 August 2013

Levels of carbon dioxide in the atmosphere rise and fall annually as plants take up the gas in spring and summer and release it in fall and winter through photosynthesis and respiration. Now the range of that cycle is growing as more CO2 is emitted from the burning of fossil fuels and other human activities, according to a study published in Science by Scripps Institution of Oceanography, UC San Diego, with CIRES and NOAA co-authors.

NASA's Firestation on way to the International Space Station

05 August 2013

An experiment to study the effects of lightning flashes on Earth's atmosphere hitched a ride to the International Space Station on 3 August 2013. The Firestation experiment launched aboard a Japan Aerospace Exploration Agency's transfer vehicle called Kounotori-4. Firestation will be installed robotically to the outside of the space station, a process that will take about three weeks.

Aerial pictures reveal climate change

01 August 2013

As a result of climate change, certain undesirable aquatic plants are starting to invade German water bodies. Even popular recreation areas like Lake Starnberg have been affected, leading to a growing need to monitor the spread of these plants. Up to now, regular monitoring has proven to be a costly process. But in a new approach, researchers at Technische Universitat Munchen (TUM) have developed a quicker and less expensive method.
