3.  HotVolc goals and capabilities WEZARD Workshop ; May 30th – June 1st 2012 ; WMO Geneva, Switzerland HOTVOLC OBSERVING SYSTEM (OPGC/LMV * ) 1. Early detection of the eruptive activity (lava flows and ash plumes, alarm procedure) 2. Localize and track eruptive volcanic products (ground / atmosphere) 3. Real-time first order retrieval (semi- quantitative – scaled intensity 1-10) 4. Near-real-time quantitative retrieval (i.e., ash concentration mg/m 3 ) 5. Real-time web diffusion of interpreted data to the end-users (i.e., decision makers, scientists) 6. Build a complete/continuous open- access archive of interpreted data Eyjafjallajökull 6-8 Mai 2010  NRT Ash concentration (mg/m 3 ) calculated every 15 mins with Meteosat  Related products: -Ash cloud height & extent -Ash radius and distribution Ash [0,5-6 mg/m 3 ]
