World leaders face multiple barriers in their efforts to reach agreement on greenhouse gas emission policies. And, according to Arizona State University researchers, without globally consistent, independent emissions assessments, climate agreements will remain burdened by errors, self-reporting and the inability to verify emissions progress.

Bardarbunga, (Bárðarbunga) in Iceland, one of the largest volcanoes in Europe and located beneath the biggest glacier in Europe, became active again in mid-August. The German Earth observation satellite TerraSAR-X has now provided important data on the volcano's latest activity.

Hurricane track forecasts have improved in accuracy by about 50 percent since 1990, but in that same period there has been essentially no improvement in the accuracy of intensity forecasts.
The Cloud-Aerosol Transport System (CATS), a new instrument that will measure the character and worldwide distribution of the tiny particles that make up haze, dust, air pollutants and smoke, will do more than gather data once it's deployed on the International Space Station this year.

Objects in space tend to spin - and spin in a way that's totally different from the way they spin on Earth. Understanding how objects are spinning, where their centres of mass are, and how their mass is distributed is crucial to any number of actual or potential space missions, from cleaning up debris in the geosynchronous orbit favoured by communications satellites to landing a demolition crew on a comet.

Organisation: European Space Agency (ESA)
Location: Frascati, Italy
The objective of this workshop is to bring scientists and Cal/Val Principle Investigators (PI) together at ESA to present and discuss the upcoming ADM-Aeolus mission and products, science applications and Calibration and Validation aspects.
A motivation is to allow Cal/Val Principal Investigators to get familiar with the mission, and to meet and coordinate their efforts in contributing to the mission validation. The Workshop shall in that respect largely contribute to the detailing of the Cal/Val Implementation Plan.
Furthermore, the scientific community are invited to present their plans for the use of the Aeolus data and to start getting familiar with the expected products and product quality.
EO Missions Database
Visit the eoPortal database to find out about spaceborne EO missions and sensors to discover more about past, operational and future missions. This is complemented with detailed articles of airborne sensors.
This database is based on the book of Herbert J. Kramer Observation of the Earth and its Environments and describes over 600 missions in detail. Online updated version of "Earth Observation History of Technical Introduction" available as of January 02, 2017.
