Following a Tropical Pacific Observing System (TPOS) 2020 workshop (27-30 January 2014, SIO, San Diego, USA), the need for a TPOS 2020 Project, to achieve a significant change between now and 2020 in all elements that contribute to the Tropical Pacific Observing System was recognised. A webinar, under the general title “Developing a Tropical Pacific Observing System for 2020”, is organised on 2 May 2014 at 8:00 GMT. Please click here for more information.
