EarthConsole® Stories: Tracking and predicting changes in river systems with ENVISAT data

EarthConsole^® Stories are experiences about how we helped universities, research centres or service developers to leverage Earth Observation data to extract valuable insights for their research, educational or pre-commercial projects.

The ESA River Discharge Climate Change Initiative aims to generate long-term climate data records—spanning at least 20 years—of river discharge for selected river basins and key locations within their networks. This will be achieved using satellite remote sensing observations, including altimetry and multispectral images, along with ancillary data. This data is essential for understanding the flow and behaviour of rivers in specific regions and at critical points along their courses. The goal is to develop a robust analytical tool capable of tracking and predicting changes in river systems resulting from climate change.

The research team, tasked with managing ENVISAT MERIS data spanning 2002 to 2012 from multiple global sites, required an efficient platform for handling this extensive dataset. They found the ideal solution in the Heritage Missions Virtual Lab, an ESA initiative hosted on EarthConsole^®. This platform provides specialized processing services for data from discontinued Earth Observation missions like ENVISAT.

Beyond data access, the team needed to generate Analysis Ready Data (ARD) for the MERIS FR datasets. For this purpose, the EarthConsole^® team developed a tool that automatically extracted time series data from approximately 25,000 MERIS FR Level 2 products, targeting specific stations within 45 worldwide sites. This process produced around 72,000 subsets, which were subsequently utilized in the neural network model developed by the team.

The EarthConsole^® G-BOX hosting service via the Heritage Missions Virtual Lab was the research team’s choice for direct access to ENVISAT Meris data.

The service was used to process Analysis Ready Data for large ENVISAT MERIS FR datasets for 45 sites worldwide with our own neural network model. In fact, the processing of the huge number of images from 2002 to 2012 would have been too time consuming to be handled on our local infrastructure. The EarthConsole^® hosting service was used to speed up the process and provide a consistent and practical method to process the multi-temporal analyses to be later on compared with the in-situ river discharge

The ESA River Discharge Climate Change Initiative will greatly benefit the research community and society by using advanced satellite technology to monitor and analyse river ecosystems over time. This project provides crucial data on river flow and behaviour, helping to track and predict changes due to climate change. Researchers, environmentalists, and policymakers will gain valuable insights, enabling better decision-making for sustainable water management and climate resilience.

This project has been supported via the ESA Network of Resources initiative.
