DataData
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
Measurement Accuracy

DataData
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
Measurement Accuracy

DataData
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
Quality Control

DataData
Viewed in context of WMO World Weather Watch Optimize the integration of GOS, GTS and Data-processing System
1. Specifications for data representation (codes, exchange formats, database design, storage of observational data)
2. Designing proper procedures in the area of data processing and telecommunications, allowing members appropriate sets of data.
3. Monitoring AMDAR operations and the quality of basic data and output products
Data Management (AMDAR-DM)
