The parameters can be grouped as follows: general parameters (simulation name, object category); last known position (start position, end position, start date, end date); simulation duration; forecasting system (wind and currents models); display settings (environmental fields on/off);

The UI visualizes the following output/results of the model: Drifters final positions (yellow or red markers); Mean trajectory drift (black curve); Drifters stranded along the coast line (red markers). REAL CASE SCENARIOS The Italian Coast Guard has been using our service to help guide search and rescue missions in the Med Sea Data from exercises and real missions is collected by us and used to test and further improve modeling

14 G l o b a l r e a l c a s e s c e n a r i o s : M a l a y s i a n A i r l i n e s F l i g h t M H On 7 March 2014 (UTC), Malaysia Airlines flight 370 vanished without a trace. The aircraft is believed to have crashed in the southern Indian Ocean, but despite extensive search operations the location of the wreckage is still unknown. The first tangible evidence of the accident was discovered almost 17 months after the disappearance. To find out how MH370 debris drifted since the crash, the researchers ran a computer model that used oceanographic data from the EU Copernicus Environment Service, including data of global surface currents and winds over the past two years. To improve their simulation, they used the locations of the five confirmed debris found to date: two in Mozambique and one each in Réunion, South Africa and Rodrigues Island (Mauritius)
