Managing Freshwater Across the United States

05 July 2019

The varied landscapes of the United States have unique relationships with water. On the East Coast, rain is a regular occurrence. In the West, drought is a constant threat. Rivers and lakes fed by rainfall, snowmelt or a mix of both provide two-thirds of the country's drinking water while also supporting agriculture.

Copernicus Sentinel-2 helps to safeguard mountain pastoral systems

28 June 2019

The Peneda-Gerês National Park in northeast Portugal has been home to wild ponies for around 2500 years. Today, it also provides a rich habitat for wolves, foxes, wild boars, ibex, and deer. It also hosts otters, fish, frogs, salamanders, 147 different bird species (many migratory) and 15 bat species. Data from the Copernicus Sentinel-2 satellites are helping to safeguard this mountainous habitat.

Satellites to the rescue after natural disasters

28 June 2019

Natural disasters showcase the widespread utility of satellite imagery. After earthquakes, landslides, hurricanes and floods, government agencies, nonprofits and emergency responders often turn to electro optical and radar imagery to gauge the severity of the damage, plan rescues, deliver aid and begin rebuilding campaigns.

A new way of Land Cover Mapping on a global scale

27 June 2019

The globalisation of the world's economy and the increase of its population has significant environmental consequences and puts pressure on land management the like of which has never been seen before. The health of our land is a foundation for economic activities as well as for the preservation of our ecosystems.

Looking For Freshwater In All the Snowy Places

20 June 2019

Snowflakes that cover mountains or linger under tree canopies are a vital freshwater resource for over a billion people around the world. To help determine how much freshwater is stored in snow, a team of NASA-funded researchers is creating a computer-based tool that simulates the best way to detect snow and measure its water content from space.

Earth's freshwater future: extremes of flood and drought

13 June 2019

NASA satellites are a prominent tool for accounting for water, as it constantly cycles from water vapour to rain and snow falling onto soils, and across and beneath the landscape. As Earth's atmosphere warms due to greenhouse gases and the satellite data record continues to get longer and more detailed, scientists are studying how climate change is affecting the distribution of water.

Mapping our global human footprint

12 June 2019

The number of people flocking to cities in search of employment and better prospects is growing at an unprecedented rate. By 2050, the global population is estimated to reach nine billion, 70% of which will be living in urban areas. The World Settlement Footprint 2015 (WSF-2015) is the first map, using mass collections of radar and optical satellite imagery, to provide a global overview of the world's human settlements.

Temperature maps from space would 'boost crop production'

07 June 2019

Scientists are developing a satellite system to record the temperatures of individual fields of crops.

The aim is to survey land temperatures to estimate water-use by plants and to show how they transfer that water back to the atmosphere.

Antarctic glaciers named after satellites

07 June 2019

Dramatic changes in the shape of the Antarctic ice sheet have become emblematic of the climate crisis. And, in deference to the critical role that satellites play in measuring and monitoring Antarctic glaciology, seven areas of fast-flowing ice on the Antarctic Peninsula have been named after Earth observation satellites.

Looking into changes in European landscapes with the Copernicus Land Monitoring Service

06 June 2019

Land is the foundation of our society and an extremely important source of economic activity. Land is also vital for filtering our water and hosting the biodiversity that helps sustain our livelihood. Efficient land monitoring is crucial to ensure rational and sustainable use of this precious resource.

Snow grain size - it matters

29 May 2019

Most of us probably wouldn't think of describing snow in terms of its grain size. However, grain size is fundamental to the amount of sunlight that snow reflects back into space – its albedo.

Copernicus Sentinel-2 helps generate "game changing" intertidal habitat maps

28 May 2019

Monitoring rapidly changing intertidal habitats is difficult, Sentinel satellites of the European Union's Copernicus Programme, can potentially be used to observe a site every few days with images that have a spatial resolution down to 10 m.

NASA-Supported Monitoring Network Assesses Ozone Layer Threats

24 May 2019

On the heels of the first definitive signs of the ozone layer recovery last year, an international team of scientists discovered that production and emission of a banned, potent ozone-depleting chemical is on the rise again. A new research finding, published in Nature on 23 May, locates the source region for about half of those new emissions. Since 2013, they found that an increase of about 7000 tons per year of trichlorofluromethane, or CFC-11, added to the atmosphere originates from eastern China.

New studies increase confidence in NASA’s measure of Earth’s temperature

23 May 2019

A new assessment of NASA's record of global temperatures revealed that the agency's estimate of Earth's long-term temperature rise in recent decades is accurate to within less than a tenth of a degree Fahrenheit, providing confidence that past and future research is correctly capturing rising surface temperatures.

Climate change may make the Arctic tundra a drier landscape

23 May 2019

With climate change, the Arctic tundra is likely to become drier. Lakes may shrink in size and smaller lakes may even disappear according to a new Dartmouth study. In western Greenland, Kangerlussuaq experienced a 28 percent decrease in the number of smaller lakes (those less than 10,000 square meters) and a 20 percent decrease in total area from 1969 to 2017. Many of the lakes that had disappeared in 1969 have since become vegetated. The findings are published in the Journal of Geophysical Research: Biogeosciences.
