The CMIP Data Request Task Team are seeking to work with community representative leads in the Earth System theme, and engage with the wider Earth System science communities, understanding data requirements for analysis of carbon and nitrogen cycles, together with chemical and bio-geochemical interactions between the physical climate, the biosphere, and reservoirs. This work is one of a set of realm papers which will develop a collection of harmonised variables and to use them to create the Earth System component of the harmonised CMIP7 Data Request. Authors and reviewers are now being sought for the Earth System theme paper.
The aim is to facilitate the creation of a controlled list of high priority variables that serve the majority of user needs in the Earth System theme and to create a harmonised set of MIP data requests which balance scientific demand for data against modelling centre and infrastructure capacity. We are seeking to ensure that those performing Earth system analysis have the appropriate data available in the CMIP7 archive. It is particularly important that authors consider the balance between demand for data volumes and appropriate use of modelling and infrastructure resources to supply data, while enabling Earth system model data users.
MIPs making significant use of earth system data are encouraged to participate. This process for developing the harmonised CMIP7 data request is designed to enable a more transparent and effective approach to variable prioritisation. In addition to our interest in the types of variables required, we would like to hear from the communities about the analyses and workflows that the variables will support, the data quality required, and the experiments and time periods for which data should be archived.
The initial focus will be on requirements linked to the IPCC 7th Assessment Cycles. In order to achieve effective engagement with the highly diverse collection of communities targeted by this activity, we are particularly interested in authors who have experience working across multiple communities (in a science, technical or facilitation role).
Physical climate is out-of-scope for this theme paper, and will be included in the Atmosphere, Ocean and Sea-Ice, and Land and Land-Ice theme papers.
Representatives of modelling centres are welcome to put forward author applications. The Author teams will be running open meetings and other engagement initiatives with modelling centres during this process.
Representatives wishing to submit an expression of interest for author/reviewer should do so here (open link).
