Temporary data upload implemented
If you want to compare and visualize you water quality measurements (point data) with information products on the GlobeWQ platform, this is now possible via a temporary upload tool for uploading CSV files. Once the browser window is closed refreshed the upload data will be cleared.

Monthly aggregates of Satellite Remote Sensing Water Quality Information available for Lake Victoria
Monthly aggregates of Chlorophyll-a concentration, Turbidity, Harmful Algae Bloom Indicator, Secchi Disk Depth, as well as inorganic, organic and total Absorption are now available on the GlobeWQ platform for the last 12 months and will be updated every month. The monthly aggregates provided an integral overview of the entire Lake Victoria and supplement the already available daily data.

Interactive Session at the World Water Week 2021 World Water Quality – Overlooked and Undervalued
GlobeWQ contributed to the Session "World Water Quality – Overlooked and Undervalued" at the 2021 World Water Week organized by the World Water Quality Alliance. Further information and an recording of the Session here.
Improving water quality is one of the major societal challenges worldwide and consequently a key issue in the UN 2030 Agenda for Sustainable Development (especially Sustainability Goal 6 ‘Ensure availability and sustainable management of water and sanitation for all’). Strategies and measures to reach this goal require coherent determination, analysis and visualization of water quality from regional to global scales. The GlobeWQ project will deliver a prototype for such an analysis and service platform.
The main goals of GlobeWQ are thus:
GlobeWQ is embedded in the World Water Quality Alliance led by the UN Environment Programme with the challenging task to compile a World Water Quality Assessment by 2023 on current and future freshwater quality. The GlobeWQ project is a direct continuation of the pre-study that resulted in a snapshot of world's water quality and a roadmap for a worldwide assessment. The GlobeWQ project is associated to the BMBF funding measure Water as a Global Resource (GRoW).
The GlobeWQ Platform integrates data from in-situ measured, remote sensing based and water quality models to inform about water quality hotspots, trends as well as the underlying drivers.
Evolving platform capabilities
We are currently developing and testing the platform by ingesting data and establishing the data interfaces to our partners and data providers. The first prototype is focused on the Lake Victoria and its tributaries. The platform currently provides access to in-situ data from the Global Freshwater Quality Database GEMStat, total modelled phosphorus loadings to the tributaries of Lake Victoria and satellite-derived water quality data. Starting in 2020, medium resolution satellite-derived water quality data (Sentinel-3) is available for the entire Lake Victoria area.
Soon, further capabilities will be implemented and the spatial coverage will be expanded. For example, in the next phase enhanced capabilities for visualizing state and trends of water quality will be implemented.
Under this category we will regularly provide in-depth insights into water quality analysis and use cases of underlying triangulation approach of GlobeWQ.
