# EDO Data Submission Requirements for C3 Leaves

We welcome users to evaluate the EDO approach and strongly encourage users to contribute their leaf-level measurements towards the development of a global CDIAC leaf database; however, users may still use the interface without their data becoming part of the larger CDIAC database.

To achieve the best possible results and to enhance the utility of your contributions for others, it is imperative those submitting data provide both the requested core leaf-level variables and the complementary information necessary to properly qualify the leaf or leaves. The desired core and companion variables are specified in the sample input file and descriptive "readme" file for each service.

The following links provide information on preparing these input files:
