Jonathan,

   I tried to re-phrase your proposal, following Alison and others on
diameters, and trying to give meaningful names (at least to me)

   I think that coordinate attribute should indicate a geophysical value
rater than and index, so now, the coordinate attribute points to
"SPP200_median_particle_diameter" rather than "size30".

   One last question I couldn't solve : should
"bounds="SPP200_bin_bounds" be a attribute of the simple index variable
("SPP200_bins") or of the the geophysices coordinate
("SPP200_median_particle_diameter") ?

   Here is my last attempt :

dimensions:
        time = UNLIMITED ; // (0 currently)
        SPP200_bins = 30 ;
        two = 2 ;
variables:
        int SPP200_bins(SPP200_bins) ;
                SPP200_bins:long_name = "bin number, from 1 up to 30" ;
                SPP200_bins:bounds = "SPP200_bin_bounds" ;
        float mic_conctab_SPP200_sync_1(time, SPP200_bins) ;
                mic_conctab_SPP200_sync_1:units = "count/cm3" ;
                mic_conctab_SPP200_sync_1:coordinates = "time
SPP200_median_particle_diameter" ;
                mic_conctab_SPP200_sync_1:standard_name =
"number_concentration_of_ambient_aerosol_in_air" ;
        float SPP200_median_particle_diameter(SPP200_bins) ;
                SPP200_median_particle_diameter:long_name = "median diameter of size
class" ;
                SPP200_median_particle_diameter:units = "micron" ;
                SPP200_median_particle_diameter:standard_name =
"aerosol_particle_diameter" ;
        float SPP200_bin_bounds(SPP200_bins, two) ;
                SPP200_bin_bounds:long_name = "lower and upper bound of size class" ;
                SPP200_bin_bounds:units = "micron" ;

Regards,

Bruno.
