In post 3120 (
http://www.pprune.org/6355188-post3120.html )there was a detail of some weather overlaid the LKP and a question was asked to Tim Vasques about his interpretation of these colours.
Tim is too busy to follow the thread but his statement about the colours is as follows:
I haven't had time to research the incident since 2009, so I don't have anything to add. I saw your link and the question about colors. The colors shown indicate overall atmospheric radiance in the 10.7 micron infrared window. This would be a measure of cloud top temperature, with the reddest colors the coldest. This has a closer relation to updraft location than it does precipitation intensity, so I would be more prone to estimate turbulence from it than rain, though they will likely be closely associated in the tropics where the atmosphere is weakly sheared.

Tim produced a magnificent report about the weather conditions which were in place at the time of the accident
