NOAA's Geostationary Operational Environmental Satellite (GOES) constellation monitors Earth's environment, helping meteorologists observe and predict the weather.
Clouds play a prominent role in moderating Earth's climate, but their role is still poorly understood. Generally, clouds cool the Earth by reflecting incoming sunlight back out into space. Reducing the cloud's reflectivity - with a layer of pollution, for example - reduces the cooling effect. New research suggests that smoke from fires may be counteracting this effect by making clouds more reflective.
The United States filled a crucial gap in its weather-forecasting arsenal when it launched its latest geostationary satellite on 01 March. The craft will enable meteorologists to track hurricanes, snow storms and other threats as they develop. It will also beam down data that researchers can use to measure air temperature and humidity — if they can work out how to incorporate them into their models.

It's another demonstration of the power of Big Data - of mining a huge batch of statistics to see patterns of behaviour that were simply not apparent before.

A NASA study based on an innovative technique for crunching torrents of satellite data provides the clearest picture yet of changes in Antarctic ice flow into the ocean. The findings confirm accelerating ice losses from the West Antarctic Ice Sheet and reveal surprisingly steady rates of flow from its much larger neighbour to the east.

Recent changes to vegetation cover are causing the Earth's surface to heat up. Activities like cutting down evergreen forests for agricultural expansion in the tropics create energy imbalances that lead to higher local surface temperatures and contribute to global warming.

NOAA-based team makes 3-D coastal models for underwater navigation, emergency management, science exhibits, and more.
You might say that ice runs in Elizabeth Hunke's blood.
The U.S. Department of Energy scientist who created the nation's premier model used by NOAA, the U.S. Navy and many scientists to predict sea ice got a taste for ice as a child.

Global sea level rise has been accelerating in recent decades, rather than increasing steadily, according to a new study based on 25 years of NASA and European satellite data.

NASA engineer Manuel Vega can see one of the Olympic ski jump towers from the rooftop of the South Korean weather office where he is stationed. Vega is not watching skiers take flight, preparing for the 2018 PyeongChang Winter Olympics and Paralympic games. Instead, he's inspecting the SUV-sized radar beside him. The instrument is one of 11 NASA instruments specially transported to the Olympics to measure the quantity and type of snow falling on the slopes, tracks and halfpipes.
The prevalence of dengue fever poses a global health issue, with half the world's population now estimated to be at risk from this mosquito-borne viral infection.

By harnessing satellite data collected from low-Earth orbit, scientists can now track the distribution of atmospheric nitrous oxide and its isotopes.

The European GNSS Agency (GSA) discusses how using European GNSS (i.e., Galileo and EGNOS) with Copernicus, Europe's Earth Observation programme, can help the world meet its Sustainable Development Goals as set out by the United Nations.
Europe is expected to see a considerable increase in flood risk in coming years, even under an optimistic climate change scenario of 1.5°C warming compared to pre-industrial levels.

Eastern France has experienced unusually heavy rainfall this month and NASA satellite data has helped determine where the largest rainfall occurred.

Observations by the Copernicus Sentinel satellites over Mount Agung in Bali, are helping scientists to monitor the ongoing eruption and identify any changes in magma pressure, possibly indicating whether a bigger eruption could occur.
On 22 January 2018, EOMAP GmbH & Co. KG, a spin-off of the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR), presented its online portal for water quality data for all inland and coastal waters worldwide at the UNESCO headquarters in Paris.
Research led by The University of Texas at Austin has found that calculations of water storage in many river basins from commonly used global computer models differ markedly from independent storage estimates from GRACE satellites.

Earth's global surface temperatures in 2017 ranked as the second warmest since 1880, according to an analysis by NASA.
