Researchers all over the world have a wealth of satellite data at their fingertips to understand global change, but turning a multitude of different data into actual information can pose a challenge. Using examples of Arctic greening and drought, scientists at ESA's ɸ-week showed how the Earth System Data Lab is making this task much easier.

Hot and dry. These are the watchwords for large fires. While every fire needs a spark to ignite and fuel to burn, it's the hot and dry conditions in the atmosphere that determine the likelihood of a fire starting, its intensity and the speed at which it spreads. Over the past several decades, as the world has increasingly warmed, so has its potential to burn.

Maxar Technologies will provide oceanographic data and saltwater fishing recommendations for SiriusXM's new Fish Mapping service announced 09 Sept. and available on Garmin International's GXM 54 satellite weather receiver.

On Monday morning, 09 September, Hurricane Dorian was a post-tropical storm after a mid-latitude weather front and cold seas had altered its tropical characteristics over the weekend. NASA compiled data on Hurricane Dorian and created a map that showed the heavy rainfall totals it left in its wake from the Bahamas to Canada.

Tracking spatio-temporal variations in flooded areas of wetlands is not an easy task, especially when they are characterised by a dense cover of emergent vegetation. Researchers in France developed a tool to monitor water in seasonal wetlands using Copernicus Sentinel-2 data, which exceed the performance of existing water indices.

While many NASA missions are tracking Hurricane Dorian as the storm makes its way toward the United States, some researchers are looking at what Dorian has already left behind.

Seeing things from a distance can help us gain new perspectives. For more than four decades, the National Aeronautics and Space Administration's (NASA) Landsat and, since 2014, the European Space Agency's (ESA) Sentinel satellites have captured images of Earth and helped humanity gain perspective on our planet and ourselves.
Through a series of case studies, EARSC (the European Association of Remote Sensing Companies) aims to gather quantitative evidence that the usage of Copernicus Sentinel data provides an effective and convenient support to various market applications. These studies are undertaken in the framework of the project "Showcasing the benefits brought by the usage of Sentinels data to society, environment and economy: a bottom-up assessment based on traceable impacts along selected value chains".
Ice fronts have retreated, rocky peaks are more exposed, fewer icebergs drift to the ocean: the branching network of glaciers that empty into Greenland's Sermilik Fjord has changed significantly in the last half century. Comparing Landsat images from 1972 and 2019, those changes and more come into view.

Daily U.S. air quality forecasts for particulate matter could potentially be more accurate as the result of incorporating NASA's Earth-observing satellite data, according to a recent study.

Thousands of fires have broken out in the Amazon rainforest. Satellite data show that there are almost four times as many fires this year compared to the same period last year. Apart from Brazil, parts of Peru, Bolivia, Paraguay and Argentina have also been affected.

NASA in cooperation with the U.S. Geological Survey is helping emergency planners in Southern California get a more complete picture of the increasing risk of coastal flooding by looking at the highest of tides —"king tides."

Thousands of fires are ravaging the Amazon rainforest in Brazil - the most intense blazes for almost a decade.
The northern states of Roraima, Acre, Rondônia and Amazonas have been particularly badly affected.
Dengue fever is a viral infection transmitted by mosquitoes. "Today the disease is endemic in 141 countries, affecting 390 million people and with a global annual cost estimated at almost US$9 billion. Since 2000, there has been an increase of over 100% in the number of cases of dengue fever in Vietnam, and there is currently no system for forecasting future dengue outbreaks." according to a Space for Development article.
Sea temperature and ocean acidification have climbed during the last three decades to levels beyond what is expected due to natural variation alone, a new study led by Princeton researchers finds.
Adopting precision farming techniques could be a paradigm shift in farmer's perception from production to productivity and to profitability.

Wildfires in the Arctic often burn far away from populated areas, but their impacts are felt around the globe. From field and laboratory work to airborne campaigns and satellites, NASA is studying why boreal forests and tundra fires have become more frequent and powerful and what that means for climate forecasting, ecosystems and human health.
A new study published this week reveals the first evidence of a direct link between human-induced global warming and melting of the West Antarctic Ice Sheet. UK-US researchers say that curbing greenhouse gas emissions now could reduce the future sea-level contribution from this region.
The dramatic loss of Arctic sea ice through climate change has only a "minimal influence" on severe cold winter weather across Asia and North America, new research has shown.
