Quality Checking Feedback

1. Quality Checking and Monitoring System (QCMS)makes analysis using numerical weather prediction (NWP)and spatial consistency check (SCC)

2. “error” = analysis - observation, done for each hour

3. Daily, weekly and monthly statistics of “error”

4. Daily and hourly “error” results saved

5. Hourly “error” mean and standard deviation mayindicate diurnal effects.
