QC Overview

• Tally variables & files

• cf-checker

• Time coordinate continuity

• Temporal min/max/mean

• Time-space cross-sections

Example QC Plots

Fixing errors

• Metadata errors: fix

• Data gaps: fill with missing_value

• Bad values: replace with missing_value

• More serious errors: contact modelers

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
