Description

Ten years ago, ARM initiated an effort to provide users with information about which datastreams are best for particular geophysical quantities. “Recommended” datastreams for a list of geophysical quantities were selected in 2012 by ARM's Technical Director Jim Mather and the ARM Translators. Now a component of ARM metadata, these recommendations are displayed in Data Discovery. However, the 2012 recommendations and list of “core” geophysical quantities need to be updated. Two efforts have been initiated: First, a major update is underway by the ARM Metadata Team and ARM Translators to ensure that recommended datastreams reflect what is currently available. Second, the ARM Data Center and ARM Translators are implementing workflows to ensure routine updating of recommended datastreams as new data are added to the ARM archive. Both efforts account for varying needs by user groups (e.g., users interested in physical processes who require high spatial and/or temporal resolution, compared with modelers who usually need data that are temporarily and/or spatially averaged). The rationale for recommendations are being documented and will be available as part of a metadata-rich recommendation. The evolving designation of data epochs will also be anticipated in the recommendation process. The new data recommendation work will directly help the users select desired data using the newly upgraded data discovery tool.
