The Severe Storm RGB

Information received from the three channels that contribute to the RGB combination

WV6.2 - WV 7.3 (difference of the two WV channels) Information about moisture content in middle/upper layers of the troposphere
IR3.9 - IR10.8 High values of the green component for cold cloud tops, high reflectivity (small ice particles) for very cold cloud tops, and lower reflectivity (normal updraft)
NIR1.6 - VIS.0.6 Information about ice and/or water clouds

Resulting colors for typical features

Blue Ocean/land
Red Convective cloud: large ice particles
Yellow Convective cloud: small ice particles

Typical application areas

  • Convective cells
  • Detection of severe storm centers
