Sequence for a cyclonic storm over western Europe

Comparison with weather radar maps

The radar images were provided by the INM, Spain,

Dr Miguel A. Martinez

The data rendering is done to maximize the similarity between day and night color interpretation of clouds, using RGB composite for the following cloud properties:

Red: Cloud depth and amount of cloud water and ice.Day: Visible reflectance at 0.6 m. Night: Optical depth, approximated by 12.0-10.8 m channels.

Green: Cloud particle size and phase.Day: Approximated by 1.6 m or 3.9 m solar reflectance component. Night: Approximated by 10.8 –3.9 m brightness temperature.

Blue: Temperature is provided by 10.8 m day and night.
