Ambient weather conditions strongly impact contrail formation and persistence. The implementation of avoidance mitigation strategies, therefore, requires regional altitude-dependent information on the frequency occurrence. To this end, we have developed a method to quantify potential cover based 10 years high-resolution reanalysis climatology data from European Center for Medium-Range Weather F...

in very recent papers asmild et al. (2003) and halved et al. (2004) based upon potential improvement efficiency index (bogetoft and hougaard,1999) have suggested an alternative nonparametric frontier approach namely multi-directional inefficiency analysis (mea) to estimate the performance efficiency. mea has many advantages over data envelopment analysis (dea) as the standard nonparametric fron...
