Hardcoded tuning adjustments for Leung_2024 dust emissions Changes to dust emissions when Leung_2024 method is being used. Tuning was needed since we saw some high biases in dust over semiarid regions given all the updates in CTSM and CAM. The biggest changes in CTSM that affects dust is an increase in friction velocity (ustar; fv in CTSM) over vegetated, semiarid regions, mainly due to a switch in the roughness scheme from 'ZengWang2007' to 'Meier2022'. Since dust emission is very sensitive to ustar, the dust emission scheme magnifies this increase and caused strong high biases over semiarid regions, including Australia and Patagonia (see plots in issue ESCOMP#2732). To enhance the robustness of Leung_2023 and reduce the likelihood to see huge changes in answers in the future, we tried to limit the sensitivity of dust emissions to ustar. We also tried different methods (see specific notes below) to reduce dust emissions from semiarid regions given the high biases over there.
