AMOC Community

Here the AMOCcommunity GitHub organization. We support open-source tools and datasets for studying the Atlantic meridional overturning circulation (AMOC), including sustained observations and community-developed analysis packages. It addresses the expectations of the CLIVAR AMOC Task Team towards making AMOC observational data easier to access.

How to contribute

We are an open community! If you want to join the effort just browse through the different repositories, raise issues or start a discussion. A good start is also to introduce yourself in the Discussions.

Initial community efforts

AMOC data

See the OceanSites website https://www.ocean-ops.org/oceansites/tma/.

RAPID 26°N

• Website: https://rapid.ac.uk/rapidmoc/
• Data: Data are provided in several formats, including *.nc or netCDF format, including vertically-gridded temperature and salinity data, the overturning volume transport streamfunction (as a function of depth and time), and a few other auxiliary products.
• Latest: Data are usually within 6 months of a cruise completion. As of April 2025, data are available partway through 2023.

OSNAP - Overturning in the subpolar North Atlantic p

• Website: https://www.o-snap.org
• Data: Data are provided in *.nc or netCDF format, including gridded fields of temperature, salinity and velocity, and overturning transports in depth and density space for both OSNAP east (east of Greenland) and OSNAP west (west of Greenland).
• Latest: Data as published in Fu et al. 2023 (for the period 2014-2020) are available (as of April 2025).
