The UK Earth Observation Climate Information Service exploits the observations available from environmental sensors orbiting in space to create climate data records and climate information. EOCIS was announced by the government in November 2022, and formally launched in March 2023. It is funded currently until March 2025.

EOCIS is a collaboration led by the National Centre for Earth Observation, and involving over a dozen research organisations. EOCIS addresses 12 categories of global and regional essential climate variables, which are the following:
- Sea surface temperature
- Ocean reflectance
- Fire occurrence and emissions
- Aerosol and particulate
- Cloud-aerosol-radiation
- Methane
- Land surface temperature
- Water vapour, ozone
- Arctic: ice sheet mass and sea ice
- Eurasia: surface methane
- Africa: soil water balance
- Antarctic: ice sheet mass and ice velocity

EOCIS is also creating new climate data at high resolution for the UK specifically. This includes both rapid-response information for climate-linked events (fire early warning and urban flood mapping) and longer term climate data linked to human and ecosystem health and landscape greenhouse gas emissions.
