Thank you, Summer Sun, for posting this comparison. Essentially all three show the same thing. In the early days of weather radar the Met Office had "quality control", a tedious operation that involved checking suspect echoes against surface observations and removing "Anomalous Propagation (AnaProp)" echoes, such as ground returns, with a light pen. This of course delayed the issuance of the imagery. Nowadays I think AnaProp is removed automatically and the forecaster/presenters have no means of altering the imagery except for choosing which layers to display, such as clouds, fog, etc. The NetWeather display is the clearest in my opinion, but a coastline and place names as the top layer would help readers to locate where they are under the veil of precipitation.
