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
