Met Office Unified Model single-site (Oden) output during MOCCHA. These model and observation data are used in McCusker et al. : Evaluating Arctic clouds modelled with the Unified Model and Integrated Forecasting System, Atmospheric Chemistry and Physics, 2023. Model data from the Met Office Unified Model are in directory 'um_model_data/'. Data are hourly data taken from grid box closest to ship location. Where the ship covers more than one grid box within an hour period, data are averaged from all grid boxes crossed. All data files are in a netCDF format, with one file per day. Rose suite ID: u-cc278. Model options include: Unified Model version - 11.3, CASIM microphysics + cloud scheme (i_cld_vn = 1). Double-moment cloud microphysics - droplet activation = Abdul-Razzak and Ghan (2000); ice nucleation = Cooper (1986). 3 modes of soluble aerosol, no insoluble aerosol. Accumulation mode soluble aerosol - num = 1.00e8 /m3, mass = 1.50e-9 kg/kg. Aitken and coarse modes = 0. No aerosol processing. Updated RHcrit ...
