Original Note:

Aircraft must maintain a vertical separation of 1000ft. Each 1000ft gives a difference of ~2 °C, 12 hPa, and 10% RH, which is sufficient to produce different contrail formations, as observed. https://www.sciencedirect.com/science/article/pii/S2590198223002002 https://rmets.onlinelibrary.wiley.com/doi/pdf/10.1017/S1350482799001115 https://www.sesarju.eu/sites/default/files/documents/sid/2022/paper_77.pdf
