Abstract

Systems and methods for monitoring conditions likely to cause persistent contrails are described herein. In certain embodiments, a method for monitoring for conditions likely to lead to aircraft-induced cirrus cloud formation, includes monitoring values that include mass ratio of water vapor, pressure, and temperature in a region of an aircraft using a combination of at least one of an optical air data system, a pitot static air data system, a spectroscopy system, and predictive values. The method also includes calculating water vapor saturation pressures for ice and for liquid water using a model and the monitored values. Further, the method includes calculating a ratio of the vapor saturation pressure for liquid water to the vapor saturation pressure for ice. Moreover, the method includes when the ratio is greater than or equal to 1, provide an indication that the conditions are favorable for aircraft-induced cirrus cloud formation.
