Radar Animation

Show all headers | View raw

I'm trying to create a radar chart using Python / Matplotlib where measured data can be "played back" using matplotlib's built in animation module. I want the data points to move along their respective axes as the data set is traversed. I have problems reading the data and updating the chart, nor am I able to find an example of this.

Okay, you said ANY help, so here goes. You mentioned accu-weather. I used weather channel app on my droid and it's been a long time but I definitely remember seeing moving radar. They also have videos you can watch which i believe were mp4 as they played well. Won't hurt to experiment.


For a really long time, the NWS (US National Weather Service) weather radar data available on the official site has been antiquated and much inferior to that offered by third-party sources, like Weather Underground, The Weather Channel, and Intellicast (though that one is no more), which are all now part of the same company, at least as far as the web sites go. The problem I had with all of those sites (Intellicast had the best of the lot for this) was that my slow Swift laptop had trouble with those relatively heavyweight pages. It would work, but scrolling or zooming was very laggy and choppy, and I often overshot the target and zoomed or scrolled more than intended.


When one sets it up to get reports from a participating weather station near where one lives (those stations are largely operated by small businesses and weather enthusiasts) updated every few minutes, one can also look at the radar images from: the nearest operational radar, the whole local area (several states) from all operational radars there, and the whole USA from all the stations across the country. As well as weather in other countries, such as: Canada, parts of the UK and, to a limited extent, Australia.


The new site is terrible for usability. I have used the old version for years, particularly the loop to see how cells and storm fronts are moving. This new version is virtually useless because the loop images are loading so slow, then seem to reload on every revolution, this is true even when using aa single radar site.


UUGGH-I am the biggest weather freak I know and the new NOAA radar, and the satellites are terrible-the satellite is at an angle that is not usable, and the radar is absolutely frustrating, incorrect, and shows inaccurate information on precipitation accumulation, cloud presence, etc.






Confirming the above: As of 2021-01-26, composite radar is still miserably slow and clumsy: a high-bandwidth product running on low-speed servers, apparently. See the NWS Anchorage page (www.weather.gov/afc/radarpage) to see their mea culpa and explanation.


The problem behind the slow load and jerky motion is because the designers load individual pages of map for each step in the loop. Then your machine has to load each page repeatedly when it displays the moving radar presentation. For some machines this really taxes the processor to do so.


The old NWS site has a static 600550 pixel image for the radar from any given radar site, representing a static space of about 250 x 225 miles. The only way to zoom it is to zoom the entire web page, and at 600550 resolution, those pixels get rather big, leaving a very blocky image. You get a .gif of several of those same static images if you want the animation. It is not possible to change the speed or stop the animation, as that is embedded into the .gif itself.


Since the initial page load is fast, but the additional radar images are slow, I would guess it has to do with prioritization at the server level, and I would think it would improve in time as they nail down the scalability issues that come from general release.


The old flash and older non-flash sites processed 20-minute radar loops in seconds, now a single radar loop (regardless if it is storm intensity, velocity, 1-hr precipitation totals, or total precipitation) TAKES UP TO 20 MINUTES!!! 


The new NWS radar web site is a disaster. Images for loops take forever to download and even after they are downloaded, the motion is excruciatingly slow and uneven. Useless to track slow moving winter storms, much less summer thunderstorms with embedded tornadoes. This is the case even when downloading data from a single radar site. The hourly and storm total precipitation images do not seem to work at all. It seems like the objective was to have a visually impressive web site rather than one that could be of use in tracking dangerous weather in real time.


nws.radarfeedback noaa.gov asking what changes I need to make to my windows 10 pc so that I can loop the new radar properly. Going to the FAQ section did not help. Perhaps if others gave feedback it might convince them there is a problem.


Wow-I use to use the NOAA radar for farming, mushroom hunting, outdoor recreation, and much more-it has made my day to find others that have the same problems as slow loading, confusing signals, odd angle for viewing, inaccurate data, etc.


I still use the Wunderground Web site, that is very easy to use, to look at local conditions, local forecasts and the plots of weather radar in the local area, the latter also at a regional level encompassing several states, and also at the whole USA + Canada level. The images are initially static, but they can be animated by pushing a button, so one can see the movement and changes in mainly stormy weather over periods ranging from 30 minutes (local) to one hour+ (regional and USA.). It has ads, but it does not mind the use of adblocker. The following URL link, if it works for you, can give you an idea of what this is like; right now, as I write this, it shows the current weather with the big snow storm in progress and can be animated to see what has happened in the last hour:


Dear sir,

I am trying to regenerate the alpha channel.

Now, I can freeze CSS3, GSAP, anine.js, and your WebVfx framework.

After freezing the animation, even 4K60 clips with alpha channel can be generated.

Then we can reuse these clips and apply the position filter merely.


On my iPhone I have MyRadar app (7.52.0.4224 - free) and would like to be able to pause the radar loop. The demo (YouTube) shows a pause button on left end of what resembles a slider bar at bottom (the one with the time stamp) but I see no such pause button on my version. Did this function get moved in the "pro" version? Thanks!


NEXRAD (Next Generation Radar) stations obtain weather information (precipitation and wind) based upon returned energy. The radar emits a burst, or pulse, of energy. If the energy strikes an object (raindrop, snowflake, bug, bird, etc), the energy is scattered in all directions. A small fraction of the scattered energy is directed back toward the radar.


The radar instrument receives a signal from this reflected energy during its listening period. Computers analyze the strength of the returned pulse, the time it took to travel to the object and back, and the phase shift of the pulse. This process of emitting a signal, listening for any returned signal, then emitting the next signal, takes place very fast, up to around 1300 times each second. Doppler radars scan the horizon in 360 degrees in a set pattern of angles from very low (along the horizon) to very high (almost straight up). A complete set of scans takes around 5 minutes to complete. These scans are interpreted by a computer and translated into an image.


I have some HA generic cameras that load animated radar maps. they display fine in all my other dashboards but in Homehabit they only show as fixed images with no animation. Is this a bug or something not yet implemented or something i am doing wrong?

While GOES animation code will not run on older Internet Explorer browsers, they work in the newest versions of Microsoft Edge. If you are using Internet Explorer, please try a different browser: Chrome, Firefox, Safari, or MS Edge are all supported.


Video / VCR Navigator. Adjust the Framerate to 10. Here you can already preview the animation by clicking the playback button. In the new dialog, that opens, you can tweak the framerate and try out this way what you like most. Just close the VCR Navigator afterwards.


For the gif format we have to adjust the mode to indexed. Image / Mode / Indexed. The defaults are fine (255 colors). Unfortunately there is no better file format for animations than gif so far, so we must put up with the loss of quality, when we want animations.


Currently it seems as if enemy radar is very limited vertically. I can run a 123m enemy radar build yet I am unable to see an enemy that is 20m above me. This can be easily seen in the Gas city due to the verticality it has.


I've been using a Weather Underground radar map in my dashboard for a long while now. Since 9/23/2023 it hasn't been updating. Going directly to the Weather Underground site yields the same issue. Any idea why this is the case? If WU is no longer a viable option, what other weather radar interactive images have people been using in their dashboards?


Unfortunately all of WU's animated radar image products have been out of date since at least mid August of 2023, the static images are current. I emailed them in August and the response was "we are aware of the issue".


NSSL's Multi-Radar/Multi-Sensor (MRMS) is a system of automated algorithms that quickly and intelligently integrate data streams from multiple radars, surface and upper air observations, lightning detection systems, and satellite and forecast models....
