            "description": "Twelve years of global deforestation, wildfires, windstorms, insect infestations, and more are captured in a new set of forest disturbance maps created from billions of pixels acquired by the imager on the NASA-USGS Landsat 7 satellite. The maps are the first to measure forest loss and gain using a consistent method around the globe at high spatial resolution, allowing scientists to compare forest changes in different countries and to monitor annual deforestation. Since each pixel in a Landsat image represents a piece of land about the size of a baseball diamond, researchers can see enough detail to tell local, regional and global stories. Hansen and colleagues analyzed 143 billion pixels in 654,000 Landsat images to compile maps of forest loss and gain between 2000 and 2012. During that period, 888,000 square miles (2.3 million square kilometers) of forest was lost, and 308,900 square miles (0.8 million square kilometers) regrew. The researchers, including scientists from the University of Maryland, Google, the State University of New York, Woods Hole Research Center, the U.S. Geological Survey and South Dakota State University, published their work in the Nov. 15, 2013, issue of the journal Science.Key to the project was collaboration with team members from Google Earth Engine, who reproduced in the Google Cloud the models developed at the University of Maryland for processing and characterizing the Landsat data; Google Earth Engine contains a complete copy of the Landsat record. The computing required to generate these maps would have taken 15 years on a single desktop computer, but with cloud computing was performed in a few days.  Since 1972, the Landsat program has played a critical role in monitoring, understanding and managing the resources needed to sustain human life such as food, water and forests. Landsat 8 launched Feb. 11, 2013, and is jointly managed by NASA and USGS to continue the 40-plus years of Earth observations.

But near the surface, the same chemical is a man-made pollutant that can cause respiratory distress. Sometimes air from the upper atmosphere descends to lower altitudes, transporting ozone with it. Such events, known as stratospheric ozone intrusions, may lead to unexpected spikes in ozone levels within populated areas. The mysterious events often take place over elevated terrain in mountainous states like Colorado, Nevada and California. In April 2012, curtains of ozone plunged from the upper atmosphere and covered parts of the western United States. Using a high-resolution model, NASA scientists simulated the event, showing where high concentrations of ozone made contact with the ground. Watch the video to see the event unfold. || ",

On that day, a fast-moving area of low pressure moved northeast across states in the Western U.S., clipping western and northern Colorado. Ozone-rich stratospheric air descended, folding into tropospheric air near the ground. Winds took hold of the air mass and pushed it in all directions, bringing stratospheric ozone to the ground in Colorado and along the Northern Front Range.Atmospheric scientists at NASA's Goddard Space Flight Center in Greenbelt, Md., set out to see if the Goddard Earth Observing System Model, Version 5 (GEOS-5) Chemistry-Climate Model could replicate stratospheric ozone intrusions at 25-kilometer (16-mile) resolution. High-resolution models are possible due to computing power now capable of simulating the chemistry and movement of gasses and pollutants around the atmosphere and calculating their interactions.They show that indeed, the model could replicate small-scale features, including finger-like filaments, within the apron of ozone-rich stratospheric air that descended over Colorado on April 6, 2012. || ",

With its archive of images capturing sprawling cities and new developments, Landsat can help FEMA track how building and construction is impacting an area’s landscapeEarth-observing Landsat satellites have been capturing images of the planet’s surface since 1972. Landsat 8 is the newest satellite in the program, a joint effort between NASA and the U.S. Geological Survey. It launched Feb. 11, 2013, and collects more than 400 images per day. New and archived Landsat data are available free to the public over the internet – and researchers have put the data to a multitude of uses. One is called the National Urban Change Indicator, or NUCI, created by MacDonald, Dettwiler, and Associates, LTD. It’s the results from a process that mines Landsat images over a 27-year period to identify areas of “permanent change,” where soil has been paved over for parking lots or other concrete structures.NUCI results act as a red flag for FEMA, helping the agency focus its mapping efforts and budget. But if maps identify a high risk of floods for a certain community, residents can take action, including elevating houses, building flood barricades, and more. || ",

By mapping projected values for a measure of dryness known as the potential evaporation—a calculation that’s based on temperature, rainfall and wind speed estimates—scientists are able to interpret how fire activity will be influenced by future climates. Changes in dryness relative to 1980 levels are shown in the animation using color, where reds represent an increase in dryness and blues represent a decrease.

            "description": "One of the most practical and efficient ways to monitor global fire is via satellites. From space, it's possible to create long-term records of burned areas on the earth. And these records show a disturbing trend: the millions of hectares burned every year by fires is increasing in the United States and most areas around the world. Some of these fires are caused by lightning, but the majority are man-made and used as a tool for forest and brush clearing, crop and pasture maintenence, or cooking. Drier climate conditions are causing both man-made and natural wildfires to burn more land. And as a result, a larger amount of carbon, stored in vegetation and biomass, is being released into the atmosphere.

The maximum increase across North America is about 1 mm/day by 2100. This concept, potential evaporation, is a measure of drying potential or \"fire weather.\" An average increase of 1 mm/day over the whole year is a big change — 1 mm/day increase in PE is considered to be an \"extreme\" event for fires, similar to the conditions in Colorado in 2012. By these projections, fire years like 2012 would be the new normal in regions like the western US by the end of the 21st century. || ",

Likewise, when soil moisture is plentiful, plant leaves cool down. Instruments on satellites can detect this micro-scale biological response, giving scientists a new way of looking at drought on a large scale. In fact, the satellite instruments are capable of sensing imminent damage before plants themselves begin to wilt, potentially giving farmers an important warning weeks early.

However, a main road bisects this wildlife corridor between the two reserves, along which numerous villages have been established over time. If the corridor is to remain open, villagers living along the route need to control sprawl. This is where scientists have joined in to help, by providing detailed satellite imagery of the area, allowing the people of the MLW region to more accurately zone their land for agricultural expansion. By providing accurate satellite zoning maps, the villages can still thrive and the wildlife corridor can remain open, which benefits both the people and the wildlife of this region of the DRC.Part of NASA's Landsat program mission is to provide tools to assist with global growth and urbanization planning.

Dramatic increases in carbon monoxide were recorded over South America in August, September, and October of that year. But a satellite instrument also saw the fire emissions travel far beyond the continent. Plumes of the colorless, odorless gas, which can linger in the atmosphere up to three months, moved across the Atlantic Ocean and likely affected the air quality over Africa. Scientists measured this carbon monoxide path using an instrument called AIRS onboard NASA's Aqua satellite. AIRS was designed to measure water vapor, clouds, and air and land temperatures. Once it was launched, scientists realized they could use it to make global carbon monoxide and carbon dioxide measurements, providing unprecedented global views of greenhouse gas distributions in the atmosphere. Watch in the visualization below how AIRS saw carbon monoxide fire emissions sweep out over the Atlantic Ocean, above Africa, toward the Indian Ocean and all the way to Australia. || ",

The season also gave rise to Katrina, one of the most intense and costliest hurricanes that resulted in 1,200 deaths and more than $100 billion in damages. The unusually high frequency and strength of these tropical storms were linked to favorable development conditions observed in the ocean and atmosphere between the Caribbean Sea and west coast of Africa where they form. Easterly winds blowing off the African continent seeded the Atlantic with a large number of proto-hurricanes—swirling air masses that grow over tropical waters. Ideal open ocean wind patterns on the surface and high above permitted storm clouds to easily mature into vigorous convective cells—the building blocks of hurricanes. Warmer ocean surface waters slightly above their 80 degrees Fahrenheit average further strengthened the storms and sent the spinning hurricanes into overdrive.

Other rainfall hotspots included New Jersey (upward of 8 inches in some counties), and upstate New York and Vermont, where satellite estimates show rainfall of up to 5.9 inches in some areas.

These chemicals, also known by the trade name Freon, were common refrigerants and widely used in aerosol spray cans prior to the Montreal Protocol. In recent years, scientists have been using cutting-edge computer models of the atmosphere to ask a fascinating question: What would have happened to the ozone layer if nations had done nothing to limit the release of CFCs? The impact of inaction, the modeling shows, would have been ominous: increased rates of cancer, cataracts, and immune deficiency diseases are just a few of the consequences. By 2065, global ozone levels would drop to less than 110 Dobson units—a measure of the amount of ozone between the surface and space. (A healthy Dobson unit reading over Antarctica is around 275.) \"We wouldn't be able to go out much at all,\" says NASA scientist Paul Newman.

The process starts in the dark of Antarctic winter as sub-freezing temperatures give rise to large numbers of wispy, iridescent clouds located high over the continent, 80,000 feet up in a layer of air called the stratosphere. The clouds are key to the depletion of ozone because a cascade of ozone-depleting reactions, fueled by human-generated chlorofluorocarbons, halons and methyl bromide compounds, occur within them. When the sun shines over Antarctica in the spring, its rays release chlorine and bromine atoms from these chemicals in forms that attack ozone. The atoms eat away as much as 70 percent of the ozone layer, creating an \"ozone hole\" to form over the region. So far, the hole appears slightly larger than it was this time last year, but it won't reach its maximum size until mid-October. In the visualization below watch the ozone hole grow from July 1 to September 16, 2011. || ",
