Cowardin classification chart
WebIn climate classification, any one of three isotherms may be used to delineate hot from cold semi-arid climates — that of 18 °C (64 °F) average annual temperature; or that of the coldest month, either 0 °C (32 °F) or −3 °C (27 °F). The warm side of the isotherm of choice is classified as BSh, the cooler side as BSk. WebThe FGDC Steering Committee endorsed the revision of the Wetlands Classification Standard in summer 2013.
