Validation of a method for the remote determination of potential aircraft icing spatial zones

[摘要] Aircraft icing remains an urgent problem of today. One of the promising means of passive temperature remote sensing in the lower (1-kilometer layer) atmosphere is a meteorological temperature profiler called MTP-5. This paper presents the results obtained by a method of remote determination of potential aircraft icing spatial zones and its validation by the example of two International Airports, Novosibirsk and Tomsk. For Tomsk, one year was analyzed (October 2012-September 2013) and for Novosibirsk, one month, January 2015. The atmosphere remote sensing method is the measurement of air temperature in the lower atmosphere layer using the meteorological temperature profiler (MTP-5) to determine the potential aircraft icing zones during landing or take-off to ensure high-quality analysis. The method, combined with the Schultz and Politovich method, shows a result similar to that obtained with the Godske method. Estimation of the icing forecasting accuracy for the two methods shows that the Schultz and Politovich method has higher accuracy than the Godske method on the data used for the two airports.
