Windy.com introduces real-time satellite animation



  • Hi there, I want to bring your attention to a problem with satellite imagery in windy. At coordinates near to 10N and 85E, there is a cyclone building up at this time and when we click to see the satellite image, there is a sync issue with two different areas of image, more precisely it is the eastern and western side of the image not syncing correctly. Please do something to fix this if it could be.
    Thanks



  • To get the worldwide mosaic map, I guess Windy merges images from geostationary satellites with different timestamps (e.g. EUMETSAT images are provided every 15 minutes, HIMAWARI every 15 minutes, GOES every 5 minutes, etc.).

    Thus it would be practically impossible to get perfectly synchronized animation, down to the last pixel, on such an area where images with different timestamps are merged.

    @Ashishweb Hello, it is not a bug, it is a matter of how the satellite imagery is synchronised.

    @Ashishweb Hi, the visualisation is a mosaic of multiple satellite images. At the ~85E meridian there is a boundary between two of them. It is hard to glue the images together. In some cases it is not possible at all.
    Images from visible part of the light spectrum are prone to lighting artifacts like scattering in atmosphere or reflections. Especially when one satellite is "looking to the sun" and sees only scattered light near the horizon. Then the picture is completely yellowish on Windy. The other satellite sees the same place from much different angle and in such case does not suffer from the actual light scattering. If you want more homogeneous image, try switching to INFRA or INFRA+. There are almost no lighting artifacts in the images, because they contain only emitted light (which is radiated in all directions with the same intensity) and therefore can be glued together quite well.



  • @ivo wow



  • Simply amazing!! Thank you Windy for providing such as amazing real-time animation!!



  • superb!

    curious - are you using an optical flow algorithm?

    @mhaberler Hi, yes, we are using optical flow.



  • Amazing Animation! Good job Windy! However, the smooth animation is not Working when using Windows 10. Only when using Mac Air. :) Hope you can fix this!

    @Typhoon2000 Hello, please check if you have the smooth animation turned on in the settings. There is no problem on Windows 10.



  • Nice, Smooth and Beautiful. Any ETA for Mobile devices?

    Love for Windy Team!
