Have you noticed that radar images craft table on yr look different? It is because we have upgraded the method of composition of images. We can now fill the radar completely or partially blocked sectors with data from other radars with coverage in that particular area. Have we 100% coverage?
As faithful yr users know, there are areas in the radar images which we never captures rainfall, despite the fact that radar images gives the impression that we should be able to capture rainfall in the area concerned. The bright circles in radar images, as in the example to the right, shows the area we can cover with radar if it has a clear view in all directions from the point where it stands on; there is no marking in the picture of where we lack information on rainfall within circles.
It's hard to find places with uninterrupted views also suitable for a radar, and unfortunately there are few of our radar has a clear view in all directions. Seen from most of our radars there are mountains or hills that takes part of the view, and reduce coverage. It has been clear to us when we considered where to place radars craft table in relation to each other; where we can place the radars to cover in sectors where one or more other radar lacking coverage? How we put together pictures
Radar images we post usually contains data from two or more radar. Certain areas are covered by multiple radar, and then we have to set up rules for how to select data from the various radars in that area. The simple method
The method we have used until today is relatively simple. There are two criteria that govern the radar to contribute data. One is the radar closest the current point in the image. The second is the height craft table above the ground craft table of the data; the further away we get radar, the higher above the ground, the data collected.
About radar selected has views to the relevant point is irrelevant with this method. And we use this method, and marks the area where the view from the radars is blocked, the image will look like the example on the right The new method
With the new method, craft table we take into account whether the selected radar views to the point in the image it will deliver data to. We calculate where we lack views, or have a blocked sector, seen from current radar. We use this information together with the two criteria of the simple method; distance to the nearest radar and height above the ground.
It means that we can fill a radars completely or partially blocked sectors with data from other radars that have coverage craft table in the area. Are we using the new method on data from the above example and enter marking area where we lack data, the image looks like the example to the right labeling of sectors where we lack data
Even with the new method of putting together radar data, we will have pictures where we lack data in some sectors. The sectors where we missing data are marked in the same way as in the example illustrating "The simple method"; sector is marked with the same gray shade as the area outside coverage.
We calculate where we have sectors with no data, and sectors where mountain and ridge steal as much of the view that we have problems capture good data on precipitation. The sectors where our calculations show that more than 90% of the signal from the radar is blocked, we mark as described previously. But there is much that affects how the signal from the radar spreads in the atmosphere, and in some cases radar
