  • The Weather Radar layer provides an estimated global radar image based off infrared satellite imagery using an algorithm which calculates cloud top temperatures with precipitation.
  • While a true global radar is not yet available due to many countries not having the adequate equipment or broadcasting capabilities, the Weather Radar Layer uses the infrared satellite layer to provide a pseudo-global radar image across the world based off these cloud top temps with regions of precipitation color coded from light (green) to moderate (yellow) to heavy (red) with a legend provided when viewed via the TOPS platform.
  • The Weather Radar Layer is useful in depicting areas of light to moderate precipitation associated with adverse weather such as low pressure centers as well as heavy precipitation associated with areas of convection. The Weather Radar Layer is also useful as an analysis of the convective layer providing a real-time estimated depiction of thunderstorms across the world.
  • The Weather Radar Overlay is updated every hour per the latest infrared satellite imagery. The refresh time and rate for the Weather Radar Overlay via TOPS is updated at XX:55 every hour.

This is an example screenshot of the Weather Radar Layer via the TOPS Flight Watch platform.
