1. Atmospheric turbulence identification to aid aviation safety USING MODIS

2. NB – for icing in aviation look at water phase clouds, below freezing (< O deg Celsius) and low pressure Band 36 (14.20 µm) – shows higher altitude conditions with clouds, NB as aircraft fly at higher alts Day 1 (30 August) – frontal system moving towards CT and cloud mass over Indian Ocean BT ranges 220.67 – 233.27

3. Day 1 - 30 August

7. wave like pattern – turbulence in clear skies seen in water vapour phase (6.78 µm) Contrast in BT temperatures – thunderstorm clouds = strong turbulence

9. Seviri
