Linking the different diameter types of aspherical desert dust indicates that models underestimate coarse dust emission

This repository contains the MATLAB scripts and results used in Huang et al. (2021), Geophysical Research Letters, doi:10.1029/2020GL092054  

We use the shape-resolved optical, geometric, and aerodynamic properties of ellipsoidal dust to link the optical and geometric diameters (in the folder "obtain_Fig1b_Fig2"), link the projected area-equivalent and geometric diameters (in the folder "obtain_Fig1c_Fig1d"), and link the aerodynamic and geometric diameters (in the folder "obtain_Fig1c_Fig1d"). We obtain a look-up table on the relationship between the optical and geometric diameters (in the folder "lookup_table"). Next, we use the obtained diameter conversions to correct the eight observational studies that sized dust using different types of dust diameter (in the folder "obtain_Fig3"). We find that substantial biases were generated if these different diameter types were not harmonized. As such, we recommend the dust research community to adopt the standardized size conversions obtained here, before they use each other's results.
