Beaucoup d’entre vous m’ont demand\u00e9 ce que je faisais exactement en Islande, du coup voici un petit post pour expliquer la mission qui nous a \u00e9t\u00e9 confi\u00e9e.<\/p>\n\n\n\n

Nous sommes deux (Hafsa et moi) \u00e0 travailler dans l’entreprise Vedurstofa qui est l’\u00e9quivalent de M\u00e9t\u00e9o France.<\/p>\n\n\n\n

L’entreprise re\u00e7oit les donn\u00e9es de tous les centres m\u00e9t\u00e9orologiques de l’\u00eele et elle est charg\u00e9e de les \u00e9tudier pour comprendre les diff\u00e9rences entre les pr\u00e9visions m\u00e9t\u00e9orologiques et le temps r\u00e9ellement observ\u00e9.<\/p>\n\n\n\n

\u00c0 la fin des \u00e9tudes comparatives, il est parfois n\u00e9cessaire de modifier le mod\u00e8le utilis\u00e9 pour am\u00e9liorer la justesse des pr\u00e9visions m\u00e9t\u00e9orologiques.<\/p>\n\n\n\n

Nous sommes donc charg\u00e9s d’\u00e9tudier les donn\u00e9es d’une dizaine de stations islandaises pour voir si le mod\u00e8le est correct ou s’il est n\u00e9cessaire d’ajouter des modifications.<\/p>\n\n\n\n

Sauf que chaque fichier contient entre 500 000 et 1 million de donn\u00e9es du coup pour \u00e9tudier \u00e7a on fait des courbes plus ou moins belles :<\/p>\n\n\n\n

\n
\n

Exemple de courbe qui ressemble \u00e0 ce qu’on peut faire.<\/em><\/p>\n

\"Exemple<\/a><\/div>\n\n<\/div>\n<\/div>\n\n
\n
\n

Exemple de tableau qui ressemble \u00e0 ce qu’on traite.<\/em><\/p>\n

\"Exemple<\/a><\/div>\n\n<\/div>\n<\/div>\n\n\n\n\n

Et \u00e0 la fin, on doit faire, d’une part, une carte de l’Islande avec la position des diff\u00e9rentes stations et les valeurs relev\u00e9es \u00e0 cet endroit :<\/p>\n\n\n\n

\n\"Entreprise\"<\/a>\n<\/figure>\n\n\n\n

Et d’autre part, un graphique permettant de comparer les valeurs observ\u00e9es \u00e0 celles obtenues lors des pr\u00e9visions avec le mod\u00e8le.<\/p>\n\n\n\n

Voil\u00e0, du coup pour r\u00e9sumer, en ce moment on \u00e9tudie l’effet des rayons du soleil sur les conditions m\u00e9t\u00e9orologiques et on regarde comment utiliser ces donn\u00e9es pour am\u00e9liorer les futures pr\u00e9visions.<\/p>\n","protected":false},"excerpt":{"rendered":"
