It's that time again to reaquaint yourself with the health and well-being of our planet. We know what you're thinking … but it's not all bad news. NOAA scientists are using their expertise and innovation to help to solve Earth's biggest challenges.
Whether they're idyllic floating cotton balls on an otherwise blue sky or ominous grey swirls that block the sun, clouds all begin as an invisible dot of water vapor. This elusive gas has been tricky to measure and track – until now. Research scientists at NASA's Langley Research Center in Hampton, Virginia, have created a new airborne instrument that can directly measure water vapor and floating particles in the atmosphere. The new data will help check the accuracy of satellite measurements, and improve weather and climate forecasts.
The complete drying-up of Lake Aculeo in Chile was captured by the Copernicus Sentinel-2 satellite, enabling scientists to follow the water surface extent at high frequency, and thus witness this dramatic loss.

Scientists are working on a technique to track plastic debris in the ocean from space.
It's extremely challenging, especially since the individual pieces of litter are smaller than the minimum-sized objects that satellites can resolve.
The Antarctic Peninsula is the northernmost part of Earth's coldest continent, making it particularly vulnerable to a changing global climate. Surface melting of snow and ice initiated the breakup of the northernmost Larsen A ice shelf in 1995, followed in 2002 by the Larsen B ice shelf to the south, which lost a section roughly the size of Rhode Island.

An extensive review reveals that remote sensing is changing the way we manage water resources and suggests that the coming years will bring both exciting advancements and new challenges.
When we think of climate change, one of the first things to come to mind is melting polar ice. However, ice loss isn't just restricted to the polar regions. According to research published today, glaciers around the world have lost well over 9000 gigatonnes (nine trillion tonnes) of ice since 1961, raising sea level by 27 mm.
When a giant iceberg breaks away from near Britain's Halley research base, it won't be because of climate change.

Why is archiving and curating heritage satellite data so fundamentally important? How can heritage data from old satellites be used to compare with current findings?

This is the last year for Operation IceBridge, NASA's most comprehensive airborne survey of ice change. Since the launch of its first Arctic campaign in spring 2009, IceBridge has enabled discoveries ranging from water aquifers hidden within snow in southeast Greenland, to the first map indicating where the base of the massive Greenland Ice Sheet is thawed, to detailed depictions of the evolving Arctic sea ice cover and the thickness of the overlying snow.

Looking up towards the stars at night, the sky can give the impression of being empty and infinite. In reality, space is getting more and more crowded every day.
From local measurements to international agreements: progress and achievements in coordinating the Copernicus In Situ Component
28 March 2019
In situ data, of various types, is an integral and important part of Copernicus products and services. We need this data to validate satellite images, generate observations not accessible from space, for instance, from deep within the ocean, and provide background maps for the Copernicus Services. As coordinator of the Copernicus In Situ Component, the European Environment Agency (EEA) is in charge of improving the access to in situ data, developing partnerships with data providers, and keeping track of the in situ data needs of the Copernicus Services. In this article, we take a look at recent progress and achievements from the Copernicus In Situ Component, showing how it supports the Copernicus Services.
At the request of Mozambique, the EU Civil Protection Mechanism has been activated to help those affected by the devastating impact of cyclone Idai. The EU is providing €3.5 million in humanitarian aid for Mozambique, Malawi and Zimbabwe as well as €250 000 to Mozambique and Malawi Red Cross Societies.

Healthy forests play an crucial role in Earth's ecosystem as growing trees take up carbon from the atmosphere. NASA satellites and airborne missions study forests to see how carbon moves through ecosystems – and now citizen scientists can help investigate this key question as well by using their smartphone to measure tree height.

Today is World Water Day, but with millions of people in Mozambique, Malawi and Zimbabwe struggling to cope in the aftermath of Cyclone Idai, the notion of water shortages may not be at the forefront of our minds right now. Even so, floods, like we see here, lead to real problems accessing clean water. Whether the problem is inundation or water scarcity, satellites can help monitor this precious resource.
The conservation and protection of biodiversity is a fundamental activity of protected areas, such as the Samaria National Park, in Greece. The use of data from the Copernicus Sentinels, combined with geodiversity variables, are proving to be fundamental in monitoring certain areas where the Podarcis cretensis endemic lizard is found.

Billions of image pixels recorded by the Copernicus Sentinel-2 mission have been used to generate a high-resolution map of land-cover dynamics across Earth's landmasses. This map also depicts the month of the peak of vegetation and gives new insight into land productivity.

Sea ice in the Arctic appears to have hit its annual maximum extent after growing through the fall and winter. The 2019 wintertime extent reached on 13 March ties with 2007's as the 7th smallest extent of winter sea ice in the satellite record, according to scientists at the NASA-supported National Snow and Ice Data Center and NASA.
The U.S. Agency for International Development (USAID) with support from NASA have initiated activities for SERVIR-Amazonia, a five-year effort that will use NASA's unique observations of Earth to address environmental and development challenges in the Amazon Basin.
