Hi everyone,
I am wondering how I can define point source passive tracer in river input.
The following cdl script on wiki roms does not have any passive tracer variable.
dimensions:
s_rho = 30 ;
river = 4 ;
river_time = UNLIMITED ; // (0 currently)
variables:
double river(river) ;
river:long_name = "river runoff identification number" ;
double river_direction(river) ;
river_direction:long_name = "river runoff grid-cell face flag" ;
river_direction:flag_values = "0, 1, 2" ;
river_direction:flag_meanings = "flow across u-face, flow across v-face, flow across w-face" ;
double river_Xposition(river) ;
river_Xposition:long_name = "river XI-position" ;
river_Xposition:LuvSrc_meaning = "i-index grid-cell of u- or v-face source/sink" ;
river_Xposition:LwSrc_meaning = "i-index grid-cell of w-face source/sink" ;
double river_Eposition(river) ;
river_Eposition:long_name = "river ETA-position" ;
river_Xposition:LuvSrc_True_meaning = "j-index grid-cell of u- or v-face source/sink" ;
river_Xposition:LwSrc_True_meaning = "j-index grid-cell of w-face source/sink" ;
double river_Vshape(s_rho, river) ;
river_Vshape:long_name = "river runoff mass transport vertical profile" ;
river_Vshape:requires = "must sum to 1 over s_rho coordinate" ;
double river_time(river_time) ;
river_time:long_name = "river runoff time" ;
river_time:units = "days since 2001-01-01 00:00:00" ;
double river_transport(river_time, river) ;
river_transport:long_name = "river runoff vertically integrated mass transport" ;
river_transport:units = "meter3 second-1" ;
river_transport:positive = "LuvSrc=T flow in positive u,v direction, LwSrc=T flow into grid-cell" ;
river_transport:negative = "LuvSrc=T flow in negative u,v direction, LwSrc=T flow out of grid-cell" ;
river_transport:time = "river_time" ;
double river_temp(river_time, s_rho, river) ;
river_temp:long_name = "river runoff potential temperature" ;
river_temp:units = "Celsius" ;
river_temp:time = "river_time" ;
double river_salt(river_time, s_rho, river) ;
river_salt:long_name = "river runoff salinity" ;
river_salt:time = "river_time" ;
