Two kinds of product are being delivered: data catalog and services.

Produced data are catalogued in a framework linked to GEOSS.  Data are related to mercury deposition scenarios (model run outputs) and to parameters defined for a statistical emulator.

A Knowledge Hub has been developed and constantly updated to provide knowledge on mercury fate at global scale. Services provided by the Knowledge Hub are catalogued and shared.

Both data catalog and Knowledge Hub are developed using an iterative approach and are currently available through a web browser (https://gos4m.org/kh). They have been now officially released. Products will still be improved iteratively when more data and service components are included, to improve the current status.

Results of the pilot are frameworks able to share knowledge on mercury pollution and mercury fate. Datasets and services are available by means of a Graphical User Interfaces and API services for Machine-to-Machine interaction.

By means of the Data Catalog, datasets can be discovered by using different searching tools, using also maps and keywords to improve its effectiveness. The datasets regarding mercury are structured by topic: Environment; Oceans; Geoscientific information; Climatology, meteorology, and atmosphere. The Data Catalog represents a “one stop site” for data/metadata and overviews of data available and includes data in various formats, as well as links to the Knowledge Hub.

The Knowledge Hub has been developed to provide to final users an effective user experience by means of a dashboard able to simulate different scenarios about mercury fate in a quick and interactive way. Numeric results of the Knowledge Hub are strictly coupled with confidence intervals. Provided predictions and widgets in the dashboard are linked to published papers to provide scientific based evidence on the provided outcomes.

Results of the Pilot will be made available through the GEO Knowledge Hub.

Both data and services are reachable by means of a web browser. Data Catalog and the Knowledge Hub are both Web Based applications.

The data catalog developed to share data and services is a customized version of GeoNetwork Open Source framework (https://geonetwork-opensource.org/).

The dashboard of the Knowledge Hub has been developed within a Java web framework, able to develop effective Single Page Application oriented to AJAX interaction with final users. The dashboard developed offers the same user experience provided by desktop applications.

The UNEP Global Mercury Fate and Transport Partnership (UNEP F&T) has the objective to provide state of the art knowledge on different aspects related to mercury releases to the atmosphere, its long-range atmospheric transport and deposition patterns to aquatic and terrestrial ecosystems and its potential impact on human health and ecosystems. The overall aim was to support the ongoing policy process that in 2017 led nations to meet in Kumamoto, Japan for the approval of the Minamata Convention on Mercury. Since then, GOS⁴M (GEO Flagship) has been contributing to the goals of the UNEP F&T and to the policy process through the participation to various ad-hoc expert groups nominated by the COPs and Nations. GOS⁴M contributed to the preparation of technical reports for the COP (i.e., GMA, Criteria for assessing the effectiveness of the MCM) and organized side events during COP2 and COP3 in which interoperable modeling tools and global EO data sets that GOS⁴M makes available to all interested parties were presented. In particular, during COP3 the GOS⁴M Knowledge Hub was presented with great success to a wide audience of policy makers and stakeholders.

The overarching goal of GOS⁴M is to promote actions aiming to provide comparable EO data sets including in-situ global monitoring mercury data as well as validated modelling frameworks that may allow policy makers and all interested parties to co-design policy scenarios for achieving the objectives of the MCM. To this end was created a federation of existing in-situ regional and global monitoring networks aimed to provide global comparable monitoring data, which include i.e., GMOS, NADP, ECCC-AMM, SAMNet, networks in China and Japan, among others. EO data sets made available by GOS⁴M includes data provided by satellite sensors (i.e., GOME, SCIAMACHY, Landsat and Sentinel-2, MODIS) used to run chemical transport models, to characterize land-use changes in Artisanal Small Scale Gold mining areas (ASGM), to better understand the exchange processes of gaseous Hg at the ocean-atmosphere interface and to assess the contribution of forest fires to the global mercury emission budget. The Pilot is demonstrating how the integration of satellite and in-situ dataset can support decision-making processes through user-friendly tools.

Datasets and other related documents are available for downloading by using the Data Catalog or the GEOSS portal where datasets and services will be linked. Being part of GEO, GEOSS Data Sharing Principles are implemented and the direct involvement in the GEO Data Working Group will follow advances in the field.

The Knowledge Hub is freely accessible using a web browser.  Citation is required for users who intend to leverage results of the framework in scientific works.

The code of the Knowledge Hub is not available for download. However, service is shared using a JSON REST API by means the service itself can be is reproduced.  

The Data Catalog is registered in GEOSS and metadata are harvested by the GeoDAB (https://www.geoportal.org/community/gos4m). A Catalogue Service for the Web (CSW) endpoint is available (http://sdi.iia.cnr.it/gos4mcat/srv/eng/csw).

SDG 3 | GOOD HEALTH AND WELL-BEING

Mercury is a harmful substance for people exposed to its organic compounds. It is released by anthropogenic sources and natural-driven emission processes, can be transported long distances from the emission region/source and be deposited to terrestrial and aquatic receptors. Once deposited to marine and fresh water ecosystems may partly be deposited to sediments and partly be bioaccumulated in biota. In marine and freshwater biota can be found at concentrations that increase with trophic levels. The impact on human health may occur through different patterns of exposure such as ingestion of Hg-contaminated food such as fish and sea food. Once bioaccumulated in human body it may have toxic effects on the nervous, digestive and immune systems, as well as on lungs, kidneys, skin and eyes, causing serious health problems.

S2P1 contributes to the estimation of:

Indicator 3.9: By 2030, substantially reduce the number of deaths and illnesses from hazardous chemicals and air, water and soil pollution and contamination
