<b>Data and model parameter files supplement the paper:</b>Title: "Co-estimation of core and lithospheric magnetic fields by a maximum entropy method"Authors: Otzen, M. and Finlay, C. C. and Kloss, C.DOI: 10.1093/gji/ggae008<b>Files Description</b>The following files are available:1. Model_CL.mat2. CL_datafile.h5<b>(1) Model_CL.mat:</b>Model parameter file of the model CL in mat-format, following thestyle of the CHAOS model releases. This can be loaded, for example, using the chaosmagpy python package https://pypi.org/project/chaosmagpy/ <b>(2) CL_datafile.h5:</b>The file stores the processed magnetic data used to estimate the model CL.Data is organized in HDF-groups "ground", "scalar", "scalar_gradient","vector", and "vector_gradient", which contains several HDF-datasets(e.g. Time, Colatitude, magnetic field B). Each HDF-dataset comes with theattributes "UNITS", "DESCRIPTION" and "FORMAT", which provide additionalinformation on the HDF-dataset. In can be read, for example using the h5py python package https://pypi.org/project/h5py/.References to the original databases:(i) Swarm and CryoSat2 data are available through ESAat https://swarm-diss.eo.esa.int/#.(ii) CHAMP data are available from GFZ Data Servicesat https://www.doi.org/10.5880/GFZ.2.3.2019.004.(iii) Ground magnetic observatory data from INTERMAGNET are availablevia the virtual research platform VirES https://vires.services/.(iv) RC index is available at http://www.spacecenter.dk/files/magnetic-models/RC/.(v) Solar wind speed, interplanetary magnetic field and Kp index areavailable through the GSFC/SPDF OMNIWeb interfaceat https://omniweb.gsfc.nasa.gov/ow.html.(vi) CHAOS-7 model and its updates are availableat http://www.spacecenter.dk/files/magnetic-models/CHAOS-7/.
