WMO AMDAR – The aircraft data source • Impact, Benefits & Future 1
WMO Data Envirnoment in Aviation:OPMET Data, WAFS • Use of ICAO – approved systems (AFTN, AFS, CIDIN, SADIS, WIFS) • Move to XML/GML Based Weather Exchange Models • System Wide Information System • Cooperation CAeM-CBS in TT Aviation XML 2
WMO Accuracy 3
WMO Accuracy 4
Data Measurement Accuracy • Pressure Altitude • Roughly 0.1% of full scale pressure measurement • Instrumental accuracy of 0.05% • Max uncertainty approx. 4 hPa • Static Air Temperature (To) • 0.44OC @ Mach 0.8 • 0.30OC @ Low Mach Rating • Additional 0.25OC at storage 5
Data Measurement Accuracy • Wind Speed/Direction • 1m/s • Direction and Vector Error • 2-3 m/s • Turbulence • 3% Variation • Relative Humidity • 20% Deviation in Upper Atmosphere • Detection Limit of 0.05g/kg • 0.05g/kg Good Perfomance 6
Data Quality Control • Measurement Stage • Done at time measurements are taken on board aircraft • Code Conversion Stage • Point at which measurements obtained are converted to GTS • Data Assimilation • Happens in non-real time • ID long term drift • Measurement bias • Consistent poor quality transmissions 7
Data Data Management (AMDAR-DM) • Viewed in context of WMO World Weather Watch • Optimize the integration of GOS, GTS and Data-processing System • Specifications for data representation (codes, exchange formats, database design, storage of observational data) • Designing proper procedures in the area of data processing and telecommunications, allowing members appropriate sets of data. • Monitoring AMDAR operations and the quality of basic data and output products 8
Current Regions • 6 Regions • I Africa • II Asia • III South America • IV N. America, C. America, Caribbean • V South-West Pacific • VI Europe • 38 Participating airlines • 10 national & regional AMDAR Programmes 9
