Aircraft-based Observations Data Quality Monitoring

While there are important but a limited number of quality control checks that can be applied to aircraft-based observations data in its pre-processing prior to GTS transmission, a critical aspect of the aircraft-based observing system Quality Management System is the routine monitoring of data both at the national level by data managers and also by international data monitoring centres, through the procedures of the World Weather Watch, Data Processing and Forecasting System, Observational Data Quality Monitoring.

Data Quality Monitoring Reports from NCEP

The Lead Centre for aircraft-based data monitoring is the World Meteorological Centre, Washington, with the data monitoring processes carried out by the USA National Weather Service, National Centers for Environmental Prediction, Central Operations.

At the current time, aircraft and AMDAR data monitoring is limited to the compilation and notification of monthly Numerical Weather Prediction (NWP) comparison reports that are available online from:

NCEP Central Operations, Quality Assessment Project

- GFS-AMDAR statistics validated against 3-h forecasts from the operational GFS model (which covers the entire world). Summary and interactive statistics for data more than 48 hours old are available to all; plan-view of GFS-AMDAR differences are restricted to those with access to real-time aircraft data.
