Description
The file "trajectories.tar.gz" contains several netCDF-4 files with about 16,000 WCB trajectories. The WCB case study was simulated with the Icosahedral Nonhydrostatic (ICON) modeling framework (version 2.6.2.2). The 66 h simulation is initialized from the ECMWF analysis at 18 UTC 03 October 2016 and run on a global R03B07 grid (approx. 13 km effective grid spacing) with a time step of 120 s.
In the WCB ascent region, we include two refined two-way coupled nests employing R03B08 and R03B09 grids (approx. 6.5 km and 3.3 km effective grid spacing) and time steps of 60 s and 30 s, respectively. These can be used as input for the software below, which gives sensitivities of specific humidity, latent heating, and latent cooling to various model parameters. The results are given in "sensitivities.tar.gz".
We provide three videos 2d_QV.mp4, 2d_latent_heat.mp4, and 2d_latent_cool.mp4 that show the evolution of the area of parameters which are most often leading order of magnitude for different heights.
