The Gap Analysis study conducted by the CLEAN Team to identify thin spots and gaps in the collection is available here: http://cleanet.org/clean/community/gap_analysis

As we continue to add more learning activities and other "useful bits" that relate to key climate and energy principles, we hope Resource Developers can help us identify existing resources or perhaps develop new resources to fill the holes.

For instance, we have no resources thus far that relate to orbital cycles and solar variability, which are important concepts for understand the climate system over time.
