DRS Schemes

In order to support multiple projects beyond CMIP5, DRSlib has been extended to support multiple DRS schemes. The --scheme switch to drs_tool will allow you to select form a set of configured schemes, currently:

1. CMIP5 (default)
2. SPECS
3. CORDEX

Each scheme has a different set of DRS components and component ordering.

When operating on projects other than CMIP5 drslib is designed to perform less metadata checks. These functions are now performed by drslib’s sister tool ceda-cc. The ceda_cc tool will verify files meet a project’s metadata requirements and output a JSON file which can be used by drslib to deduce certain metadata values that are not apparent from the files. This JSON file is passed to drs_tool using the –json-drs option.
