The project ambition was to fill this information gap by first enhancing satellite-based geodata with innovative in situ sensors and development of actionable information services based on this geodata. This ambitious goal was achieved thanks to recent advances in sensor and communication technology, as well as new sensing platforms such as UAVs and citizens’ observatories. A defining characteristic of TWIGA’s ambition was that the project developed complete value chains and not just links in that chain. The scientific activities led to new products, such as maps of precipitable water vapor, energy fluxes, and crop development. Combinations of in situ observations, satellite products, and models will be well beyond the state-of-the-art, not just in Africa but for any continent.
