[CF-metadata] Specifying a wavelength for a standard_name

[sdj at tiscali.it]

Dear All,
In reference to a previuous discussion about the standard name 
"Diffuse Attenuation Coefficient", may I ask if the following notation 
is correct to represent Diffuse Attenuation Coefficient at 490nm ?

<ncdump -h kd490.nc>

float kd490 (x, y)
        kd490:standard_name = 
"volume_attenuation_coefficient_of_downwelling_radiative_flux_in_sea_water" 
;
        kd490:long_name = "Mean Diffuse Attenuation Coefficient at 
490nm" ;
        kd490:coordinate = "490nm" ;
        kd490:units = "m-1" ;

Is this the correct way to specify the wavelength, or do I need to add 
a different/another attribute somewhere else ?

Many thanks for your help.

Regards,
Pepe
