Atmospheric turbulence identification to aid aviation safety USING MODIS.

Atmospheric turbulence identification to aid aviation safety

USING MODIS

• 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

Day 1 - 30 August

wave like pattern – turbulence in clear skies seen in water vapour phase (6.78 µm)

Contrast in BT temperatures – thunderstorm clouds = strong turbulence
