. "The quantity with standard name magnitude_of_derivative_of_position_wrt_model_level_number (known in differential geometry as a \"scale factor\") is | (dr/dk)ij|, where r(i,j,k) is the vector 3D position of the point with coordinate indices (i,j,k). It is a measure of the gridblock spacing in the z-direction."@en . . . "1" . "" . "2008-10-21 10:00:00.0" . "SDN:P07::CFV10N16" . . . "2008-10-21 10:00:00.0" . "SDN:P07::CFV10N16" . "1" . "false" .
