We are pleased to announce that new Level 3 products have been added in the Climate Data Store (CDS) on 15-10-2025 for the following two entries:
- Methane data from 2002 to present derived from satellite observations
- Carbon dioxide data from 2002 to present derived from satellite observations
The new products include:
- the column-averaged mixing ratio products version 4.6 for both Carbon Dioxide and Methane. These products are referred to as “XCO2” and “XCH4”.
- the Mid-tropospheric mixing ratio products version 10.1 for Carbone Dioxide and 10.2 for Methane. These products are referred to as “MTCO2” and “MTCH4”. They have now daily temporal resolution and will have ICDR updates every six months.
For more details please have a look at the documentation.
Please be aware that no further updates for L2 products are expected.
