This is a pure computational kernel implementing Fengsha Dust emission scheme developed at NOAA ARL for use at NOAA NWS. NO error checking, validation, or infrastructure concerns. Host model must ensure all inputs are valid before calling.

Parameters:

• num_layers Number of vertical layers
• num_species Number of chemical species
• params Scheme parameters (pre-validated by host)
• g0 Required constant from Constants module
• airden AIRDEN field [appropriate units]
• clayfrac CLAYFRAC field [appropriate units]
• frlake FRLAKE field [appropriate units]
• frsno FRSNO field [appropriate units]
• gvf GVF field [appropriate units]
• lai LAI field [appropriate units]
• lwi LWI field [appropriate units]
• rdrag RDRAG field [appropriate units]
• sandfrac SANDFRAC field [appropriate units]
• soilm SOILM field [appropriate units]
• ssm SSM field [appropriate units]
• tskin TSKIN field [appropriate units]
• ustar USTAR field [appropriate units]
• ustar_threshold USTAR_THRESHOLD field [appropriate units]
• z0 Z0 field [appropriate units]
• species_radius Species radius property
• species_lower_radius Species lower_radius property
• species_upper_radius Species upper_radius property
• species_conc Species concentrations [ppm or ug/kg] (num_layers, num_species)
• species_tendencies Species tendency terms [mol/mol/s] (num_layers, num_species)
• dust_emission_total Total dust emissions for all bins [kg/m2/s]
• dust_emission_per_bin Dust emission flux per bin [kg/m2/s] (num_species)
• dust_horizontal_flux Total horizontal flux - Q [kg/m2/s]
• dust_moisture_correction Moisture Correction - H [1.0]
• dust_effective_threshold Effective Dust threshold friction velocity: u_thres * H / R [m/s]
• diagnostic_species_id Indices mapping diagnostic species to species array (optional, for per-species diagnostics)
