This includes the development of the first FRP Product developed from a geostationary satellite, in this case the European Meteosat Second Generation. From these data, wildfire location and their rates of fuel consumption across Africa and Europe can be updated every 15 minutes. A link to the Google Earth version of the product can be found here, and the data are used for a variety of operational services as well as science applications, for example to forewarn of times when wildfires are likely to move close to power lines in parts of Africa such that the line can be temporarily turned off to prevent damaging ‘flashovers’ (sparking events).

A 10-Year Endeavor: NASA's Aura and Climate Change. Nitrogen and oxygen make up nearly 99 percent of Earth's atmosphere.

A 10-Year Endeavor: NASA's Aura and Climate Change

The remaining one percent is comprised of gases that -- although present in small concentrations -- can have a big impact on life on Earth. Trace gases called greenhouse gases warm the surface, making it habitable for humans, plants and animals. But these greenhouse gases, as well as clouds and tiny particles called aerosols in the atmosphere, also play vital roles in Earth's complex climate system. Home Page - Orbiting Carbon Observatory. Aerosol Optical Depth : Global Maps. Download a Quicktime animation of this dataset (5 MB) Tiny solid and liquid particles suspended in the atmosphere are called aerosols.

Aerosol Optical Depth : Global Maps

Windblown dust, sea salts, volcanic ash, smoke from wildfires, and pollution from factories are all examples of aerosols. Depending upon their size, type, and location, aerosols can either cool the surface, or warm it. They can help clouds to form, or they can inhibit cloud formation. And if inhaled, some aerosols can be harmful to people’s health. These maps show average monthly aerosol amounts around the world based on observations from the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite. High aerosol amounts are linked to different process in different places and times of year.

In other cases, however, aerosol concentrations are not related to fires. View, download, or analyze more of these data from NASA Earth Observations (NEO): The EOS Flagship. Aqua Earth-observing satellite mission. GMAO - Research. Animation 1.

Aerosols: Tiny Particles, Big Impact : Feature Articles

By Adam Voiland Design by Robert Simmon November 2, 2010 Take a deep breath. Even if the air looks clear, it’s nearly certain that you’ll inhale tens of millions of solid particles and liquid droplets. These ubiquitous specks of matter are known as aerosols, and they can be found in the air over oceans, deserts, mountains, forests, ice, and every ecosystem in between. They drift in Earth’s atmosphere from the stratosphere to the surface and range in size from a few nanometers—less than the width of the smallest viruses—to several several tens of micrometers—about the diameter of human hair.

Aerosols—tiny, airborne solid & liquid particles—are present throughout the atmosphere and largely responsible for hazy skies, as in this photograph of Shenzen, China. Different specialists describe the particles based on shape, size, and chemical composition. Aerosols / Space for our climate. Aerosols Tiny dust particles and droplets suspended in the atmosphere have a definite influence on our climate, but we are a long way from defining precisely the role that aerosols play. That they do have an effect was established more than a decade ago. Volcanic dust Mount Pinatubo devastated the Philippines when it erupted in 1991, forcing half a million people from their homes.

The largest eruption for a century, its wider effects was felt across the world. This mass of aerosols stayed circling the globe for three weeks – and temporarily reversed the effects of global warming. MACC Project - Home. Meteosat. Climate studies to benefit from 12 years of satellite aerosol data / Space for our climate. Climate studies to benefit from 12 years of satellite aerosol data Aerosol optical depth measured by SEVIRI 10 November 2009 Aerosols, very small particles suspended in the air, play an important role in the global climate balance and in regulating climate change.

For all life on Earth, it functions as a combined life support system and protective shield. About GOSAT - GOSAT Project. The Greenhouse Gases Observing Satellite "IBUKI" (GOSAT) is the world's first spacecraft to measure the concentrations of carbon dioxide and methane, the two major greenhouse gases, from space (Figure 1). The spacecraft was launched successfully on January 23, 2009, and has been operating properly since then.

Through analyzing the GOSAT observational data, scientists will be able to ascertain the global distribution of carbon dioxide (CO2) and methane (CH4), and how the sources and sinks of these gases vary with seasons, years, and locations. These new findings will enhance scientific understanding on the causes of global warming. Also, they will serve as fundamental information for improving climate change prediction and establishing sound plans for mitigating global warming. The GOSAT Project is a joint effort of the Ministry of the Environment (MOE), the National Institute for Environmental Studies (NIES), and the Japan Aerospace Exploration Agency (JAXA) (Figure 2).

Sentinel-3 The Sentinel-3 mission's main objective is to measure sea-surface topography, sea- and land-surface temperature and ocean- and land-surface colour with high-end accuracy and reliability in support of ocean forecasting systems, and for environmental and climate monitoring. Sentinel-3 builds directly on a proven heritage pioneered by ERS-2 and Envisat. Its innovative instrument package includes: A Sea and Land Surface Temperature Radiometer (SLSTR), which is based on Envisat's Advanced Along Track Scanning Radiometer (AATSR), to determine global sea-surface temperatures to an accuracy of better than 0.3 K.

Introducing Sentinel-2 / Sentinel-2 / Copernicus. The Sentinels are a fleet of satellites designed specifically to deliver the wealth of data and imagery that are central to the European Commission’s Copernicus programme. This unique environmental monitoring programme is making a step change in the way we manage our environment, understand and tackle the effects of climate change and safeguard everyday lives.

Introducing Sentinel-1 / Sentinel-1 / Copernicus. The Sentinels, a new fleet of ESA satellites, are poised to deliver the wealth of data and imagery that are central to Europe’s Copernicus programme.

ESA's Living Planet Programme ESA's Living Planet Programme ESA has been dedicated to observing Earth from space ever since the launch of its first Meteosat meteorological satellite in 1977.

Following the success of this first mission, the subsequent series of Meteosat satellites, ERS-1, ERS-2 and Envisat provided us with a wealth of valuable data about Earth, its climate and changing environment. It is crucial, however, that we continue to learn more about our planet if we are to understand the Earth system and its processes, especially within the context of global change. This will equip us better for predicting the effects a changing climate may bring. As our quest for knowledge continues to grow, so does our demand for accurate satellite data to be used for numerous practical applications for protecting and securing the environment. In addition, the Copernicus Sentinel missions, which form part of the Copernicus Space Component, will collect robust, long-term climate-relevant datasets.
