Madeira island radar.



  • Hi there,

    I have noticed your scale settings for the Madeira radar might be wrong. The radius should be 300km instead of a 100Km.

    Thanks and Best Regards,

    I asked exactly the same recently from @dzuremar and he said it's because of the source decreased its range due to some reason. For Madeira they not get the official data, but they get it from Rainviewer.com. Anyway as you can see recently there are a lot of newly added radar coverages, these big and fast extensions are thanks to Rainviewer (such as: Portugal, Turkey, W part of Russia, Australia).

    @csabatatar Oh boy, thanks for mentioning me in the comment. Now that I can see precipitation in the image, I see that the problem is not different range. The map projection is wrong. Note that the precipitation "clouds" are the same, but the scale is wrong (the island is way bigger on the Windy image). I already contacted Rainviewer.com , its creator Oleksii usually responds and fixes these minor problems quickly. It will be fixed soon. Thanks for the post !

    @dzuremar
    I found some precipitation out of the radar ranges. Maybe does it the same projection error, or does it a range problem?

  • @csabatatar
    Some wx. radars are "adjusted" to send images at different range at different time steps.
    Example: LGPZ wx. radar (marked by a star).

    @Gkikas-LGPZ @csabatatar Yes this happens often, it's a configuration error. The routine that draws those light gray circles does not know anything about the underlying radar data (over which it draws the circles). Sometime radar sites have incorrect range in the configuration (e.g. off by several kilometers), or the data can change. Plus, very probably I will be reworking the central/south american radar so probably this will be fixed to a degree :-), but still you can find these things often.



  • Hi there,

    Again the Madeira radar data. The scale seems to be correct now. Thanks.
    I noticed another problem, even though the coverage area has a 300 km radius, data is only being shown for a 100 km radius.

    By the way, would it be possible to reduce the delay of the data presentation? It can take about half an hour to update.

    Keep up with the outstanding work, thanks and best regards.

    @ecavaleiro Thanks for feedback ! Yeah, scale is right, but I missed a small problem that caused the range mask not to update so the image was still clamped to the wrong radius. Should be fixed now ! About the update time - I can't do anything with the delay unfortunately :/ it depends on the data source (both https://www.ipma.pt/en/otempo/obs.radar/ and rainviewer.com)

    Do you use rainviewer for germany radar too? Or the free open data from DWD?


  • Developers

    @Tomber42 Germany is free open data. Here is the list of countries we process ourselves: Taiwan, Czechia, Germany, Estonia, Spain, Finland, France, Italy, Netherlands, Norway, Poland, Romania, Sweden, Slovakia, United Kingdom (covers Ireland too), Canada, USA.
    The rest is via Rainviewer.

    But why is then in germany the update intervall 20 minutes..it was 5 min before :(


  • Developers

    @Tomber42 It's still updated in 5 minute intervals ;-) nothing changed there. However, it takes around 10 minutes for the data to be displayed in the client (e.g. data that correspond to Germany precipitation at 14:00 are usually displayed around 14:10). I'll ask around whether there is a possibility to speed up this delay. The 20 minutes delay you experienced earlier was some kind of server hiccup. Usually it should be around 10 mins.
