Obs4MIPs encourages use of CCI datasets in a wide range of research
- Obs4MIPs is a climate model community initiative to encourage widespread uptake of satellite observations for climate model verification and development.
- CMUG is supporting the CCI projects to contribute their data to Obs4MIPs, these datasets include:
- Sea Surface Temperature (SST)
- Carbon Dioxide (CO2)
These data can now be easily compared to CMIP6 data and to other Obs4MIPs datasets facilitating their use in high profile publications such as IPCC reports which draw heavily on results from CMIP in their assessments.
Obs4MIPs products are mature, well documented, easy to access and provided in a standard format . This encourages their uptake by removing many of the common barriers to use of satellite data in research .
The Obs4MIPs products are formatted and organised according to the model output requirements of the WCRP's Coupled Model Intercomparison Project (CMIP) . They are made available on the Earth System Grid Federation (ESGF) with the archive of CMIP model output data, so that both observations and model output are searchable via the same portals. Each Obs4MIPs observational dataset corresponds to a biogeophysical field that is output by a climate model in one or more of the CMIP experiments. This technical alignment of observational products with climate model output can enable model evaluation, development and research.
Use of CCI data through Obs4MIPs
A number of publications have used the CCI data from the obs4MIPs portal, e.g., CO2 , methane . Most of these also utilise the ESMValTool (see briefing note on ESMValTool). An example of the data used is shown in Figure 1 from .
