This Aerosol Report is a continuation of the modeling discussed in the previous Carnicom paper ‘AEROSOL REPORT – US’ on May 2, 2001. This model was developed to determine whether atmospheric conditions in the United States are favorable or unfavorable to aerosol operations. Using this predictive model and data collected in Santa Fe, New Mexico in 2001, the probability that conditions in the southwestern United States are favorable to aerosol operations is estimated to be 29%.
A preliminary model is presented here to be used to predict whether contrails will form or not under reported meteorological conditions at flight altitude. Contrail prediction models are difficult to attain, so this model is presented for investigative purposes only. This model can and will be evaluated with actual observations in an effort to test it for reliability.
