Using mainly MSG data (from the 0 degree service), it provides information on clouds related to significant convective systems, from mesoscale (200 to 2000km) down to smaller scales (a tenth of km).

Some of the objectives of RDT are:

  • The identification, monitoring and tracking of intense convective system clouds
  • The detection of rapidly developing convective cells.

The object-oriented approach underlying the RDT product allows for adding value to the satellite image by characterising convective, spatially consistent, entities through various parameters of interest to the forecaster such as motion information, cooling and expansion rate, cloud top height, etc.

The layer is available as both WMS and WFS. When clicked on an RDT cell, a number of attributes are shown in the Point Information window.

The attributes are:

  • Minimum Brightness Temperature within the cloud top
  • Cooling rate as °C per minute
  • Brightness Temperature difference between overshooting top and tropopause. -9,999.0°C if no overshooting top is detected
  • Pressure at Cloud Top
  • Direction of motion
  • Speed of motion
  • Life phase
  • Average Brightness Temperature within the cloud top
  • Maximum value of Convective Rainfall Rate product within the cloud. -9,999.0mm/h in case of no CRR value availability
  • Duration of the cell since first detection

For more information about the RDT product please visit the NWC SAF web page.

As part of this new EUMETView release, ASCAT Coastal Winds product will be started to be stored as a rolling archive of 18 months, in order to improve the back-end performance of the system.
