The External Drift Kriging - EDK program

Table of Contents

EDK-LOGO

This repository contains the external drift kriging (EDK) Fortran program developed at the Dept. Computational Hydrosystems at the Helmholtz Centre for Environmental Research - UFZ.

The EDK program comes with a LICENSE agreement, this includes also the GNU Lesser General Public License.

Please note: The GitLab repository grants read access to the code. If you like to contribute to the code, please contact steph.nosp@m.an.t.nosp@m.hober.nosp@m.@ufz.nosp@m..de or sebas.nosp@m.tian.nosp@m..muel.nosp@m.ler@.nosp@m.ufz.d.nosp@m.e.

Installation

Installation instructions can be found in INSTALL for Windows, MacOS, and GNU/Linux distributions.

The simplest way to compile the EDK program is to use a conda environment (on Linux (including Windows/WSL) or MacOS) provided by Miniforge:

conda create -y --prefix ./fortran_env
conda activate ./fortran_env
conda install -y git cmake make fortran-compiler netcdf-fortran liblapack
source scripts/compile

This will give an executable edk.

Usage

To run the EDK program, you need a set of station data files, a look-up-table for these stations and a DEM file for the external drift. All configuration is done with a namelist file, which is called edk.nml by default. See the example file for all input specifications.

Then you can just execute ./edk next to this file.

You can also explicitly specify the namelist file and/or change the working directory by passing options the the edk command like:

./edk -n edk.nml check/case_01

To see the help text, execute:

./edk --help
