This guidance document and webinar provide information about the CA LCC method for creating and updating a Data Management Plan for CA LCC-funded projects. A Data Management Plan is a document that describes the data produced by a project and the way those resources will be stored, documented, and if and how they will be shared for use by others. Data Management Plans are required of all CA LCC-funded projects. CA LCC’s Data Managers assist Principle Investigators in starting and updating their Data Management Plans throughout the lifespan of their project, culminating in the delivery of the products and making them accessible on the Climate Commons when appropriate.
