The limitations of current instrumentation in measuring the microphysical and optical properties of contrail cirrus elevate the importance of models for estimating their radiative forcing. Accurately determining the intricate relationship between contrail microphysics and chemistry often necessitates the use of costly large-eddy simulations. The study highlights the need to understand the impacts of contrails on climate due to projected increases in air traffic, which poses a significant challenge for mitigation strategies.
