MSG Satellite images
Meteosat 9 IR10.8 - Time sequence
In this series of images the convective developments over the Balearic Islands are described using plain Meteosat infrared 10.8 μm. The channel is appropriate as it pictures the ice particles from high clouds quite clearly. In a sequence of 15 minutes the relevant satellite image are presented.
Meteosat 9 Enhanced IR10.8 - Time sequence
In this chapter again Meteosat 9 infrared 10.8 μm is shown, but the images have been artificially color enhanced. This will improve the discrimination of where most ice particles form during the several convective stages. In a sequence of 15 minutes the satellite images are presented and described.
Meteosat 9 WV6.2 - Time sequence
The chapter presents the several convective developments over Mallorca using Meteosat 9 WV6.2 channel. The channel is suitable as it gives an idea of the upper tropospheric humidity (UTH) and gives a view of the upper air dynamics. 15 minutes sequence of images are presented.
Meteosat 9 HRVIS - Time sequence
This chapter will show the HRVIS images of 4th October. Especially with the smaller scale cells the high resolution channel allows us a very good monitoring of the convective development. In a sequence of 15 minutes the satellite images are presented and described.
Meteosat 9 Severe Convection RGB - Time sequence
The Severe Convection RGB makes use of the NIR1.6 and IR3.9 μm channels. Both of these channels provide information on the microphysics within the clouds. E.g. with this RGB we are able to discriminate between smaller and larger ice particles. This is useful for detecting convection. Cells that are bound to severe updraft will likely be characterised by smaller ice particles, as there is less time available for the ice particles to collide and form bigger particles. When a cell has reached its mature stage we will find larger ice particles. With this in mind click the above link and study the set of Severe Convection RGB images to identify at what stage the updrafts within the MCS is the highest and at what time step the cell reaches its mature stage.
Meteosat 9 Dust RGB - Time sequence
As the names says the Dust RGB is useful for detecting dust. Already in Fig 2.1 (Modis image) we could recognise the presence of dust. However using this RGB is also very helpful when looking at convection. You will learn that with this RGB you can easier discriminate between the thick ice part of a convective cell and the anvil which is a thin cirrus shield.
