Date des données :<\/strong> 2025<\/p>\n

Source des données :<\/strong> Hydroclimat<\/p>\n

Projection :<\/strong> Lambert 93 (epsg : 2154)<\/p>\n

Zone :<\/strong> France métropolitaine<\/p>\n
\n

Cette couche contient des variables climatiques concernant l\u2019aléa Sol<\/strong> et en accord avec le projet TRACC. Elle résulte de l\u2019agrégation des informations issues de trois couches distinctes : TRACC_Sol_Scenario_2_0_degres_Polygone, TRACC_Sol_Scenario_2_7_degres_Polygone et TRACC_Sol_Scenario_4_0_degres_Polygone.<\/p>\n\n

Elle décrit l\u2019exposition initiale au risque de retrait-gonflement des argiles (RGA), d\u2019après les données du BRGM. On y retrouve le niveau d\u2019exposition pour la période de référence (1976\u20132005), ainsi que des projections du risque associées à trois niveaux de réchauffement climatique en France métropolitaine : +2,0°C, +2,7°C et +4,0°C.<\/p>\n\n

L'information peut être croisée avec les carreaux des autres aléas à l\u2019aide du champ \"Index\".<\/p>\n\n
