The CLIVAR Exchanges special issue on Tropical Atlantic Ocean Observing System (TAOS) is now published online (doi: 10.36071/clivar.82.2022). Based on its 10‑year review of the Tropical Atlantic Observing System (TAOS) coordinated by the CLIVAR Atlantic Region Panel (ARP), in close cooperation with PIRATA, this special issue on  TAOS aims to disseminate the important findings from the TAOS review report more widely and highlight the societal relevance of TAOS. The special issue contains ten articles documenting the history and current status of TAOS, the key science and operational driver, as well as the recommendations for future TAOS development derived from the TAOS Review report.
