Aerosol activation lookup table (LUT) for CAMS/IFS-COMPO CY49R1

Description This lookup table (LUT) was produced with offline simulations of aerosol activation with the adiabatic parcel model by Rothenberg and Wang (2016), Pyrcel. Results for prescribed vertical velocities between 0.1m/s and 1.0m/s were integrated over normal distributions of vertical updraft, over a range of mean ([-0.2 m/s,0.2 m/s]) and standard deviation ([0.1 m/s, 2.5 m/s]) values. Represented species: Sulfates Nitrates Sea salt fine Sea salt coarse Organic matter Soot Activation LUTs: Activated number fractions ("*_num_act") Activated mass fractions ("*_mass_act") Critical dry activation radii ("*_crit_rad_eq") Maximum supersaturation ("supsat_max") Height of maximum supersaturation ("supsat_max_hei") Final temperature of the parcel ("t_max_simul") It was used to perform offline cloud-top Nd optimisation - optimisation code available at GitHub:pandreozzz/optimindReferences Rothenberg, Daniel and Chien Wang (2016). “Metamodeling of Droplet Activation for Global Climate Models”.
