High-frequency (20 Hz) aircraft measurements of tropical tropopause layer (TTL) cirrus and humidity are used to examine recent homogeneous freezing ice nucleation events. Several localized regions with peak ice concentrations greater than 10 cm −3 are documented. These high ice concentrations are almost certainly generated by homogeneous freezing of aqueous aerosols. The high-frequency data reveals considerable structure in the cloud properties and humidity at along-track scales as short as 8.5 m. Simulations of vapor depletion by growing ice crystals are used to assess the time since nucleation in these high ice concentration patches. Comparisons between observed and simulated dependence of supersaturation on ice
