About project
Water vapour (H₂O) in the atmosphere is a key component of the Earth’s hydrological cycle, critical in shaping the global environment and supporting life on Earth as we know it.
The Water Vapour project is generating four key deliverables, which include Climate Data Records (CDRs) of both total column water vapour over land and ocean (CDR-1 and CDR-2), and vertically resolved water vapour (CDR-3 and CDR-4).
- Total column water vapour over land, CCI TCWV-land (CDR-1) is now available - see Data for details.
These CDRs are working towards satisfying the key user requirements of the climate research community that were defined at the beginning of the project and are being updated throughout the lifetime of the project. If you want to get involved in the user group of our water vapour products and help define climate data record requirements, please contact the Science Lead of the Water Vapour project.
