Carbon Footprint of Nations website wins recognition

How much carbon does your country emit - and where does it come from? Norwegian University of Science and Technology (NTNU) Professor Edgar Hertwich and colleague Glen Peters wanted to know the answer to that question - and created a website to do so.

Some interesting pages on volcanos

The pages refer to research projects, some completed and some ongoing, and is for general interest.

ESA-NRSCC Dragon Cooperation Programme

ESA, together with the National Remote Sensing Centre of China (NRSCC), have created a dedicated three-year Earth Observation exploitation programme called Dragon (2004 to 2007). The Dragon programme focuses on science and applications development in P.R. China using mainly data from the ERS and Envisat missions. There are numerous Dragon Programme research themes, which range from flood monitoring, agriculture and forests, to seismic activity, oceanography and climate. The latest Dragon Symposium took place in Santorini, Greece between 27 June and 1 July 2005, and was attended by 120 scientists including 50 from PRC. Progress and early results were reported during the event and updates were given on project teaming, including Greek scientists joining as co-investigators. Supporting in-situ data measurements required to validate satellite results were detailed and reports were made from an associated young scientist training programme.

Presentations included details of research being done into the synergistic use of ASAR with Envisat's optical Medium Resolution Imaging Spectrometer (MERIS) and also how ocean colour measurements made by MERIS can reveal marine phytoplankton populations, as well as suspended sediment. Researchers are building up a database of water optical properties as well as atmospheric correction for the region and developing a method of monitoring "red tide" events. MERIS is also being used to look at the estuary of the Yangtze River, whose waters have some of the highest sediment concentrations in the world. Teams are using Envisat's heat-sensitive Advanced Along Track Scanning Radiometer (AATSR) in conjunction with ASAR and MERIS to study the Kuroshio Current, which is the Chinese equivalent of Europe's Gulf Stream, flowing from the Philippines to northern Japan.
