Collaborating with SPC on Kiritimati project

Two 10-years models hindcast at 150 m and 1km resolution

In a partnership with The Pacific Community (SPC), SIROCCO has develloped two level simulation at 1km and 150m resolution to produce Hindcast over 10 years (2010-2019) for the oceanic circulation arround Kiritimati island (Republic of Kiribati).

The first stage at 1km is forced at the ocean open boundaries with the Mercator global ocean analysis ( and atmospherci forcing are provided by the ECMWF ERA5 reanalysis (

Then the second stage at 150m is using the SYMPHONIE model at 1 km resolution as openboundary condition, ECMWF ERA5 and the Tidal componant are rovided by the FES2014 global ocean tide atlas (

The Pacific Community has made the simulation results available on a web page for both resolution :

Recent publication: Seasonal and annual budget of dissolved inorganic carbon in the NW Med deep convection area

Researchers from LEGOS, NIOZ, LOV, MIO, Espace-Dev, SCCWRP, LOCEAN, and CEFREM investigated the seasonal to annual cycle and budget of dissolved inorganic carbon in the deep convection area of the north-western Mediterranean, using a coupled physical-biogeochemical model. Their results show that the northwestern Mediterranean Sea’s deep-convection region was a moderate sink of 0.5 mol C […]
