Latest SCIAMACHY Stories
The loss of the Envisat satellite is affecting services by Europe’s Global Monitoring for Environment and Security program. Efforts are being coordinated with other space agencies to fill some of the gaps, but the situation adds further urgency to launch the Sentinel missions.
In the early hours of 1 March 2002, the largest Earth observation satellite ever built soared into orbit from ESA’s launch base in Kourou, French Guiana. For a decade, Envisat has been keeping watch over our planet.
ESA’s Envisat observation satellite yesterday completed its 50,000th circuit of Earth – travelling 2.25 billion km since its launch nearly a decade ago.
Originally designed to monitor Earth for just three years, ESA's veteran ERS-2 satellite is still in orbit and going strong after 15 years of delivering essential data to improve our understanding of Earth and climate change.
By merging more than a decade of atmospheric data from European satellites, scientists have compiled a homogeneous long-term ozone record that allows them to monitor total ozone trends on a global scale â€“ and the findings look promising.
The SCIAMACHY sensor on ESAâ€™s Envisat satellite has provided scientists with invaluable data on our planet, allowing them to map global air pollution and the distribution of the most important greenhouse gases.
Using data from the satellite-based MIPAS and GOME-2 instruments, scientists have for the first time detected important bromine species in the atmosphere.
The 2008 ozone hole â€“ a thinning in the ozone layer over Antarctica â€“ is larger both in size and ozone loss than 2007 but is not as large as 2006.
Using data from the SCIAMACHY instrument aboard ESA's Envisat environmental satellite, scientists have for the first time detected regionally elevated atmospheric carbon dioxide â€“ the most important greenhouse gas that contributes to global warming â€“ originating from manmade emissions.
Air pollution is becoming one of the biggest dangers for the future of the planet, causing premature deaths of humans and damaging flora and fauna. With their vantage point from space, satellites are the only way to carry out effective global measurements of air-polluting emissions and their transboundary movement.
