Dear All, I would like to retake the thread that I initiated a few weeks ago about cloud properties from instrument simulators. Following suggestions by Jonathan and others, I've reduced my original list to the one below, where I've taken out all the references to instruments like isccp,calipso, etc.
- cloud_albedo [1] - atmosphere_optical_thickness_due_to_cloud [1] - atmosphere_optical_thickness_due_to_stratiform_cloud [1] - atmosphere_optical_thickness_due_to_convective_cloud [1] - stratiform_cloud_longwave_emissivity [1] - convective_cloud_longwave_emissivity [1] - surface_longwave_emissivity [1] - toa_brightness_temperature_assuming_clear_sky [K] - toa_brightness_temperature [K] - toa_reflectance [1] - large_scale_graupel_flux [kg m-2 s-1] - sunlit_binary_mask [1] (1=day,0=night) - attenuated_molecular_backscatter [m-1 sr-1] - attenuated_backscatter [m-1 sr-1] - equivalent_reflectivity_factor [dBZ] - radiation_frequency [s-1] - hydrometeor_effective_radius [m] Hydrometeor is any kind of condensate (liquid water, graupel, ice, rain, etc). This will need a coordinate hydrometeor_type that stores the names of the hydrometeors. The following three are derived from some of the above. If I follow strictly the CF guidelines, what it is usually called scattering ratio becomes ratio_of_attenuated_backscatter_to_attenuated_molecular_backscatter [1] And what are usually called CFADs (Contoured frequency with altitude diagrams) of X become histogram_of_equivalent_reflectivity_factor_over_height_above_reference_ellipsoid [1] and histogram_of_ratio_of_attenuated_backscatter_to_attenuated_molecular_backscatter_over_height_above_reference_ellipsoid [1] I don't think this is practical, so I would propose to use backscatter_scattering_ratio instead of ratio_of_attenuated_backscatter_to_attenuated_molecular_backscatter.
