On 4 August ESA's Earthwatching service requested a full resolution MERIS (Medium Resolution Imaging Spectrometer) acquisition over the areas in Portugal affected by the fire. The Portuguese Civil Protection then requested emergency planning on 6 August, through the Charter. The first acquisition was made via Artemis on 7 August.
The Charter is an international collaboration to combine international satellite resources to assist participating rescue authorities and other civil protection agencies. ESA participates in the Charter together with Argentina , Canada, France, India and USA.
In this image burnt areas appear as very dark patches to the north-east of Lisbon, close to the centre of the land part of the image, along the Tagus River. Lisbon itself is visible south of the large whitish area at the mouth of the Tagus. The image covers all of Portugal plus part of Spain's Galicia region.
Use of Artemis for data relay offers Earth observation missions greater visibility and reduces delays in image reception. Artemis has been providing a data relay service to Envisat and the French national mission SPOT 4 since March of this year.
Artemis is ESA's latest telecommunications satellite, designed to qualify new space technologies and promote new services. It also carries payloads for land mobile communications and a navigation payload as an element of the European Geostationary Navigation Overlay Service (EGNOS).
