wget and curl are the two standard tools that are available on most Linux and macOS computers. wget contains a feature for downloading a list of files: 
wget -x -nH -i 'https://opendata.physik.lmu.de/mcnfx-nry46/?list'
curl is missing a feature like that, but the same functionality can be created by combining curl and xargs: 
curl 'https://opendata.physik.lmu.de/mcnfx-nry46/?list' | xargs -I URL -n1 bash -c 'curl --create-dirs -o ${1:31} ${1}' -- URL

Data for "Diagnostics for Imbalance on the Convective Scale"

Author: Theresa Diefenbach (LMU Munich)

This dataset features output data from the Kilometer-scale Ensemble Data Assimilation (KENDA) system of the German Weather Service (DWD). KENDA employs a Local Ensemble Transform Kalmam Filter (LETKF) coupled with ICON-D2 the regional numerical weather model of DWD. The data was produced using ICON-KENDA in a near-operational set-up. The model simulations are initialized at 12:00 UTC each from the same reference experiment provided by DWD. The ensemble comprises 10 members. The data is stored minutely between 13.00 UTC and 14:00 UTC.

Each folder in this repository contains one of the experiments analysed in the respective publication.

Experiment Settings
noDA no data assimilation between 12:00 and 14:00 UTC
LHN latent heat nudging switched off at 13:00 UTC
LETKF LETKF data assimilation at 13:00 UTC
IAU As the LETKF but with incremental analysis update between 12:55 UTC and 13:05 UTC

The netCDF output files were interpolated to rotated pole coordinates using the "ICON-tools" software of the DWD. The interpolated data is found in the int_latlon folders of each experiment folder. The native ICON grid type was R19B07.
