GFZ Metadata Schema for International Generic Sample Numbers (IGSN) and documentation

This publication includes the metadata schema and documentation for the registration of International Generic Sample Numbers (IGSN) by GFZ Data Services between 2015 and 2024. The IGSN schema definitions included here give an overview of the existing elements for sample description used in the different data centres managed by the IGSN Agent GFZ Data Services. To date, GFZ Data Services organises their IGSN collections according to different projects or research groups which are displayed as different datacentres in the catalogue (https://dataservices.gfz-potsdam.de/igsn-new/). The modular IGSN metadata schema, developed by IGSN e.V., formed the basis for the registration of IGSN sample descriptions. Until 2022, the following three modules were used: IGSN Registration Metadata Schema: mandatory metadata properties required for the IGSN registration (Handle Server) IGSN Descriptive Metadata Schema: generic description of a specimen’s core elements as defined by IGSN e.V. These elements were intended to represent the common metadata kernel for all IGSN allocating agents. IGSN Supplemental Metadata Schema: additional, sample-specific metadata elements that can be individually developed by IGSN Allocating Agents. This schema represents a further development of the IGSN metadata schema originally developed by System for Earth Sample Registration (SESAR², www.geosamples.org) in the framework of the IGSN Organisation (IGSN e.V.) with specific additions for the GFZ use case. It was used for IGSN registrations since 2015. As part of the project "FAIR Workflows to establish IGSN for Samples in the Helmholtz Association" (FAIR WISH), funded by the Initiative and Networking Fund of the Helmholtz Association (Helmholtz Metadata Collaboration HMC). these schemes were secured and the documentation for the registration metadata, descriptive metadata documentation was completed.

FAIR WISH Software Tool: SAMIRA: FAIR SAMPLES Template Processing

Physical samples (or specimen or artefacts) represent the origin of research results in many scientific disciplines. Assigning persistent identifier (PID) to samples is a fundamental step to make them discoverable and traceable in unambiguous way over the Web. The International Generic Sample Number (IGSN) is a PID for physical samples and connecting these with their online description following a dedicated metadata schema. Sample descriptions of samples are available in various formats and detail. In order to publish them in a standardized manner and to automate and standardize the preparation and processing, the software product SAMIRA (Sample IGSN Registration Automation) was created as part of the Project FAIR WISH, funded by the Helmholtz Metadata Collaboration (HMC). SAMIRA aims to automate the generation of Metadata XML-Files for the Registration of PIDs from different input sources (e.g. the FAIR Samples Template, Wiezcorek et al., 2023). This first version of SAMIRA implements the creation of IGSN metadata and Datacite metadata and the respective registration.

ITSG-Grace2018/ ITSG-Grace_operational Level-L2B Products Filtered Stokes coefficients

Filtered GRACE/GRACE-FO spherical harmonic coefficients of ITSG-Grace2018/ITSG-Grace_operational Level-2 GSM products representing an estimate of Earth's gravity field variations during the specified timespan. The spherical harmonic coefficients are filtered with VDK3 filter (anisotropic filter taking the actual error covariance information of the underlying GSM coefficients into account, see Horvath et al. (2018)). The filtered spherical harmonic coefficients are accompanied by their variance-covariance matrices which are gained via variance propagation from the variance-covariance matrices of the unfiltered coefficients. This data set is basis of Boergens and Kvas (2021) and have been used in Boergens et al. (2021) to produce regional time series and their uncertainties, which can be reproduced with the code provided by Boergens (2021).

Post-processed GRACE/GRACE-FO Geopotential GSM Coefficients COST-G RL01 (Level-2B Product)

Version History: 15 June 2020: Initial release of the data. Note that the initial version number is 0002 in order to reflect the consistent data processing of this data set and Version 0002 of the data set Dahle & Murböck (2019, http://doi.org/10.5880/GFZ.GRAVIS_06_L2B). --------------------------------------------------------------------------------------------- Post-processed GRACE/GRACE-FO spherical harmonic coefficients of COST-G RL01 Level-2 GSM products representing an estimate of Earth's gravity field variations during the specified timespan. Post-processing steps comprise: (1) subtraction of a long-term mean field; (2) optionally, decorrelation and smoothing with VDK filter (anisotropic filter taking the actual error covariance information of the underlying GSM coefficients into account, see Horvath et al. (2018)); (3) replacement of coefficients C20, C30 (only for the months starting from 2016/11 and later), C21 and S21 and its formal standard deviations by values estimated from a combination of GRACE/GRACE-FO and Satellite Laser Ranging (SLR); (4) subtraction of linear trend caused by Glacial Isostatic Adjustment (GIA) as provided by a numerical model; (5) insertion of geocenter coefficients (C10, C11, S11); and (6) removal of estimated aliased signal of the S2 tide (161 days period). These coefficients represent signals caused by water mass redistribution over the continents and in the oceans. These post-processed GRACE/GRACE-FO GSM products are denoted as Level-2B products. There are multiple variants of Level-2B products available that differ by the characteristics of the anisotropic filter applied. These variants are distinguishable by the following strings in the product file names: - 'NFIL': Level-2B product is not filtered - 'VDK1': Level-2B product is filtered with VDK1 - 'VDK2': Level-2B product is filtered with VDK2 - 'VDK3': Level-2B product is filtered with VDK3 - 'VDK4': Level-2B product is filtered with VDK4 - 'VDK5': Level-2B product is filtered with VDK5 - 'VDK6': Level-2B product is filtered with VDK6 - 'VDK7': Level-2B product is filtered with VDK7 - 'VDK8': Level-2B product is filtered with VDK8 The individual auxiliary data sets and models used during the post-processing steps mentioned above are provided as well (in the aux_data folder): - 'GRAVIS-2B_2002095-2020091_GFZOP_0600_NFIL_0002.gz': Long-term mean field calculated as unweighted average of the 183 available GFZ RL06 GSM products in the period from 2002/04 up to and including 2020/03. - 'GRAVIS-2B_COSTG_GRACE+SLR_LOW_DEGREES_0002.dat': time series of coefficients C20, C30, C21 and S21 estimated from a combination of GRACE/GRACE-FO and SLR - 'GRAVIS-2B_GIA_ICE-6G_D_VM5a_0002.gz': Model from Peltier et al.

GRACE-FO Geopotential GAD Coefficients GFZ RL06

Spherical harmonic coefficients that are zero over the continents, and provide the anomalous simulated ocean bottom pressure that includes non-tidal air and water contributions elsewhere during the specified timespan. These coefficients differ from GLO (or GAC) coefficients over the ocean domain by disregarding upper air density anomalies. The anomalous signals are relative to the mean field from 2003-2014.

GRACE-FO Geopotential GAC Coefficients GFZ RL06

Spherical harmonic coefficients that represent the sum of the ATM (or GAA) and OCN (or GAB) coefficients during the specified timespan. These coefficients represent anomalous contributions of the non-tidal dynamic ocean to ocean bottom pressure, the non-tidal atmospheric surface pressure over the continents, the static contribution of atmospheric pressure to ocean bottom pressure, and the upper-air density anomalies above both the continents and the oceans. The anomalous signals are relative to the mean field from 2003-2014.
