. "'frozen_water' means ice. 'Content' indicates a quantity per unit area. 'Layer' means any layer with upper and lower boundaries that have constant values in some vertical coordinate. There must be a vertical coordinate variable indicating the extent of the layer(s). If the layers are model layers, the vertical coordinate can be model_level_number, but it is recommended to specify a physical coordinate (in a scalar or auxiliary coordinate variable) as well. Quantities defined for a soil layer must have a vertical coordinate variable with boundaries indicating the extent of the layer(s)."@en . . . "SDN:P07::CFSN0626" . . . . "2006-09-26 18:12:43.0" .
