Ionospheric plasma is often characterised by irregularities and fluctuations in its density. Plasma density irregularities and fluctuations can influence the propagation of trans-ionospheric radio waves and are thus of importance for any operations that rely on precise positioning with Global Navigation Satellite Systems (GNSS). Indeed, ionospheric scintillations are one of the most important observed space weather effects. Understanding ionospheric plasma irregularities and fluctuations is thus of both scientific and practical interest. In this project we develop a high-level, global product based on Swarm satellite measurements that will characterize ionospheric irregularities and fluctuations, and addressing the needs of scientific community and operational users. Products resulting from IPIR will be visualised within the virtual research service - VirES for Swarm.
