WIGOS Technical Report, 2016-01. AMDAR Benefits to the Air Transport Industry
This report describes and documents the benefits that the Air Transport Industry (ATI) gains from increased forecast accuracy achieved through the daily collection of atmospheric data gathered by approximately 4,000 inflight commercial aircraft. The report also outlines the Aircraft Meteorological DAta Relay (AMDAR) observing system, the forecast process and describes the importance that AMDAR data plays in numerical weather prediction (NWP).

This report describes and documents the benefits that the Air Transport Industry (ATI) gains from increased forecast accuracy achieved through the daily collection of atmospheric data gathered by approximately 4,000 inflight commercial aircraft. The report also outlines the Aircraft Meteorological DAta Relay (AMDAR) observing system, the forecast process and describes the importance that AMDAR data plays in numerical weather prediction (NWP).
Measuring the benefits to the ATI requires first to describe and to quantify the improved weather forecast accuracies due solely to the assimilation of the AMDAR data into NWP and its availability to meteorologists. The effects and impacts of the resulting improved forecasts are categorized according to their characteristics (linear1, threshold, etc.) and in relation with each operational activity performed by each ATI sector and function.
For the airlines, we can clearly quantify the benefits of more accurate wind forecasts especially on the fuel burn calculation and fuel load made prior to flight. The impacts during flights and for the other operational activities are more difficult to model. Statistical data for each operational decision derived from better forecast accuracy would be needed to make such assessments. These ‘relational’ statistics are less likely to be documented and much more complex to evaluate. Indeed complex weather phenomena (like convective storms, icing, fog, etc.) are the primary disruptive sources to ATI operations and their prediction certainly is improved with the availability of AMDAR data. However, we are able to leverage a modeling method which relates the Weather Impact Traffic Index (WITI) and the Forecast Accuracy Index (WITI-FA) to calculate an economic impact accounting for the significant role that AMDAR plays in increasing weather forecast accuracy. For other operational activities and aspects of the ATI, there is considerable and well-justified subjective evidence and testimony of the positive impact and value of AMDAR data.
The report therefore provides strong quantitative and ample qualitative evidence of significant benefits and costs savings to be gained from ATI support and participation in the WMO AMDAR Program.Collection(s) and Series: WIGOS Technical Report- No. 2016-01
