Water Vapour

The Water Vapour project aims to generate new global high-quality climate data records of both total column and vertically resolved water vapour.

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 aims at 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).

These CDRs will work towards satisfying key user requirements of the climate research community that are defined at the beginning of the project and 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 Water Vapour project. Below follow short descriptions of the different CDRs.
