Overview of Data Quality Control and Archiving at NARCCAP Workshop

This presentation by Seth McGinnis discusses the current status of data archiving and quality control (QC) processes at the 4th NARCCAP Users Workshop, held at NCAR in Boulder, CO. Key topics include the current archive status, an overview of the QC process, derived data products, and the data pipeline's simulation and post-processing stages. The talk also highlights ongoing QC efforts, future processing needs, and resources for users, including derived variables, tools for citation, and sharing software.

  6. QC Overview • Tally variables & files • cf-checker • Time coordinate continuity • Temporal min/max/mean • Time-space cross-sections

  7. Example QC Plots

  8. Fixing errors • Metadata errors: fix • Data gaps: fill with missing_value • Bad values: replace with missing_value • More serious errors: contact modelers

  9. Derived Data Products • Derived variables: tools on website • Temporal averages & climatologies • Regridded to 0.5-degree lat/lon grid • Online GIS access via databasin.org • New gridded daily obs: MICA
