Set cox54a,cox54b ocean BRDF properties.  

brdf_cam variable value

 
variable can be one of the following:

pcl

Pigment concentration for cox54a,cox54b ocean BRDF (in mg/m{}^{{-3}}). The default value is 0.01 mg/m{}^{{-3}}.

sal

Salinity for cox54a,cox54b ocean BRDF (in ”per mille”, 0.1%; this unit is equivalent to the other common units for salinity, ppt - parts per thousand, psu - practical salinity unit). The default value is 34.3.

u10

Wind speed for cox54a,cox54b ocean BRDF (in m/s). The wind speed is the most important parameter affecting ocean BRDF. The minimum allowed wind speed is 1 m/s because otherwise the strong specular reflection causes numerical problems. If a lower value is specified, the wind speed is automatically set to 1m/s.

uphi

Wind direction for cox54a,cox54b ocean BRDF. Default value is 0 degrees, which is wind from the South. 90 degrees corresponds to wind from the West, etc. (Honestly, this was never truly validated. It could possibly be that 0 is wind from the North, 90 is wind from the East, etc.)

At present only available with rte_solver cdisort, rte_solver montecarlo and rte_solver fdisort2. The number of streams (number_of_streams) is automatically increased to 16 if cox_and_munk BRDF is switched on, to avoid numerical problems. To switch on Cox and Munk BRDF, specify any of the brdf_cam options and define at least brdf_cam u10.
