Over land, sea and air, users give MERIS high marks



 
Proceedings during ESA's 2003 MERIS User Workshop, attracting more than 150 principal investigators, students and representatives from industry to Frascati in Italy during the week starting 10 November.

Ground work
 
Typhoon Maemi, 13 September 2003
 
The Medium Resolution Imaging Spectrometer (MERIS) instrument onboard Envisat satellite acquired this image of Typhoon Maemi over the Sea of Japan when it weakened into a tropical storm some hours later of tearing into South Korea (seen in the centre of the image). The typhoon hit the southern coast of the peninsula with gale winds blowing at a record 216 kilometres an hour. Media reported of at least 72 people were killed and 24 missing by the time the storm subsided. Maemi is the Korean name for a cicada that legend says chirps madly to warn of a coming typhoon. The mouth of the Yangtze River can also be seen in the bottom left part of the image spilling out sediments into the East China Sea about 23 kilometres north of Shanghai.

She shared her experiences using MERIS to monitor algae blooms responsible for blighting Chilean aquaculture. The hope is to build an operational forecasting system for bloom outbreaks in future.

Santiago, 2 March 2003
 
Most of the country of Chile can be observed on this Medium Resolution Imaging Spectrometer (MERIS) image, particularly the area surrounding the capital, Santiago, in the centre-right of the image, shown in grey. Scrolling down, the main cities of Rancagua, Curico, Talca, Chillan and Concepcion are clearly visible. Along the right side of the image are the snow-capped mountains of the Andes Chain.
