Air-sea CO₂ gas fluxes calculation tools

OceanFlux data online configurator

Version 3 now includes:

• auto-installers and/or install instructions (e.g. you can use it on a Windows, Linux or Mac laptop)
• new capability to calculate CH4 and N2O gas fluxes
• extensive support for analysing in situ data (e.g. you can calculate gas fluxes from SOCAT and MEMENTO data)
• the toolbox is now a Python library (so you can use it from within your own code)
