The collaboration between the Istituto sull’Inquinamento Atmosferico del Consiglio Nazionale delle Ricerche and ASI has resulted in the availability of the entire catalogue of PRISMA acquisitions on the GEOSS portal. Users can now access and query the catalogue without registration. The catalogue data is updated daily to ensure coherence with the PRISMA mission system catalogue. By including PRISMA in the missions handled by the GEOSS portal, the GEOSS user community will become aware of PRISMA coverage and can perform multimission queries with other datasets indexed in the portal. However, to obtain the PRISMA hyperspectral dataset, users still need to register for free on the PRISMA system. The PRISMA catalogue on the GEOSS portal can be accessed from here.
