MetUM Simulations of 2nd February Case Study

This repository contains data to support the publication "Kilometre-scale simulations of trade-wind cumulus capture processes of mesoscale organization" submitted to JAMES.

The data is from Met Office Unified Model simulations of the 2nd February 2020 EUREC4A case study. There are 3 kilometre-scale resolutions (1.1km, 2.2km, 4.4km) nested in ERA5 boundary conditions, and two 100m-scale resolutions (300m, 500m) nested in the 1.1km simulation. The simulations are initialised at 1st February 00:00. Also included are two sensitivity tests with the kilometre-scale simulations run with 1) evaporation of rain switched off and 2) a later start time (2nd February 00:00).

The code used to analyse this data is at https://github.com/leosaffin/moisture_tracers.

The data is across four folders (full directory structure at the bottom)

regridded - Contains model data regridded to the lowest resolution (4.4km) either fixed on the 100m-scale domain (coarse_grid) or following a Lagrangian trajectory for the kilometre-scale resolutions and sensitivity tests (lagrangian_grid). There are also files with model data following a different trajectory and smaller domain, to be consistent with Narenpitak et al. (2021), for the default kilometre-scale simulations (lagrangian_grid_Ron_Brown).

trajectories - Contains all the trajectories used to extract the domains in "regridded"

simulated_satellite - Contains model simulated brightness temperatures from 11Z-21Z for each resolution simulation. These simulations were run with the same setup but on a different machine and also include a 150m-resolution simulation.

full_grid - Contains 2d model output a T+36 from the 500m and 1.1km simulations which were used to make figure 1 in the paper.
