East & West Malaysia weather radar No Data

East & West Malaysia weather radar No Data. See below screenshots:
West Malaysia:
East Malaysia:
Malaysia's Met office weather radar webpages show last radar images from 8:50AM (GMT+8): https://www.met.gov.my/en/pencerapan/radar-semenanjung/
https://www.met.gov.my/en/pencerapan/radar-sabah-and-sarawak/
So the lost of data seems to be at the source. -
@hangInThere Unfortunately, we take these data from external source, which had an outage, it should be okay now.
-
@Ondřej-Šutera Malaysia's weather radars seem back online. See image below. But on Windy at the same 3:50AM you can see the rain near Kuala Lumpur on the middle west coast of the Peninsula as shown in the MetMY radar image is not shown in Windy's (2nd weather radar image). The displayed rain distribution seems centered Pekanbaru on Sumatera Island west of the Strait, and gets cut off by the edge of circle centered at Pekanbaru. If you do receive weather radar data from MetMY, the data may be corrupted, or the unit of precipitation could be changed resulting in incorrect interpretation of magnitude.
-
@Ondřej-Šutera The problem still persists. The Malaysia Met department's webpage shows heavy rain in the Strait of Malacca west of Kuala Lumpur half to midnight, but Windy shows nothing.
-
@hangInThere I believe the current images from MetMalaysia show same data as windy:
Or am I mistaken?
-
@Filip_K These two images you posted are for different times of the day. Furthermore, the highest intensity rain areas to the east of the peninsula are in different places: one being nearly on shore, the other at least 100km out to the sea.
-
@hangInThere I see, the images are misplaced too much to the west. I'll work in fixing that
-
@Filip_K Just took a newest screenshot w/ MetMY Peninsula weather radar image and Windy side by side below. Windy image shows high intensity rain on the shore near Kuala Lumpur, whereas MetMY shows there's only 1mm/hr drizzle there but high intensity rain is ~100km inland. The discrepancy is huge.
It appears the rain pattern in Windy for Peninsula central west is shifted ~100km to the west. Something in the coordinate of the data or in its interpretation by Windy?
-
@hangInThere Yes, the geolocation of radar images for Malaysia is completely wrong (they are positioned in the wrong place). I will fix that
-
@Filip_K That's fast! I just screenshot Singapore's radar image for the same 9PM and showing rain area that matches MetMY much better.
-
@Filip_K Okay, now Windy radar matches MetMY's. Thanks.
-
@Filip_K By the way, is there any chance the shortest playback interval of weather radar can be increased to 2hr from the present 1hr. This is so that I can open weather radar in one window and satellite image in another window and run playback side by side to help visually correlate between the rain and cloud patterns. Currently, I can't do this, so what I do is taking screenshots of the static displays side by side every 10 minutes for the duration I need and then play them back in slideshow mode in an image viewer. This is very inefficient, but is the only way I can get a synchronized view of weather radar and satellite images in motion.
-
@Ondřej-Šutera The No Data problem has returned to weather radar layer. But this time the Malaysia Met dept's weather radar page is good, whereas Windy's weather radar No Data involves not only the Malay Peninsula but also the Pekanbaru radar at Sumatera. See below images.
-
@hangInThere I've implemented new processing for radar data from MET Malaysia and since now, outages and geo misalignment should not happen
-
@Filip_K The misalignment (west shift ~100km) is back. See below Windy compared with MetMalaysia. But it sometimes returns to normal, as it just did for the newest frame (3rd image below).
-
@hangInThere At that time, switch to faulty secondary source happened. I've disabled that secondary source
-
@Filip_K Thanks!
