Radar slider

I have been watching the radar and it takes 7 minutes before it updates and when it does it is still 2 minutes behind real time.
In a severe weather situation not being able to view up to the minute radar could be a big problem.
I for one liked the old radar better it was up to the minute. -
@condor1956 Thank you for your feedback, we will follow the issue and evaluate potential changes. At this moment, it is not possible to turn this off.

Hi @condor1956, where are you located? Radar data layer should be updated as quickly as possible whenever new data from source are available.

Please let us turn it off! It is just annoying

I made a comparison on browser version (with “Radar” forecast) vs mobile app (without “Radar” forecast).
There is for me a difference of 3 minutes but absolutely no difference in the picture.
It is funny to see that during so many years users were claiming a “future radar” and now they are not here … but only some who do not want it.

Ah, I see. The visualization from previous version (that is still used in the app) used update time from latest frame as timestamp. The new version (used on web) aligns data to 5min slots/frames (which is what we use internally anyway). That is why the data look same (because they are) but the timestamp is different (which is just matter of visualization) and that is unfortunate.We'll might have to rethink how we display the metadata

@condor1956
NOAA provides updated radar composite every 2 minutes, each radar scan takes around 7 minutes. Data are as fresh as they were before, timestamp display is different for the reasons I described in the previous post. -

Thank you,

@Suty kiedy można się spodziewać nowej wersji aplikacji mobilnej z tymi zmianami ?
-
@przemo1986 We started to test our mobile apps and we are still waiting for the feedback about the web app. So I would say one or two weeks at most.
-
How is the forcast created ?
-
@camplanes Our product team based their calculation on many variables from observed data.
-
@Suty If you guys want for france there is a model that does the exact thing
https://portail-api.meteofrance.fr/web/en/api/PrevisionImmediatePrecipitations
could be a interesting idea to grab the data from there -
@camplanes
OK that’s new -
@idefix37 I think @camplanes means new future forecast data that are available in web app and we calculate them on our end.
-
@idefix37 I'm right here! It just took me a little bit to notice it ;)
-
@Suty Yeah i meant what was the process on your end and then giving out the info that MétéoFrance opened a lot of data including this forecast model for Rain Rate that is more or less what you did your side but the data is derived from radars observation and the last run of AROME-PI (Immediate forecast )and then runs into the future at 5 minutes interval for the folowing 3 hours and run every 5 minutes
@idefix37
Yeah quite a lot of data is now public and reusable
got a topic referencing all about it right Here -
@camplanes
I did not realize that AROME-PI (prévision immédiate) was a Nowcasting model just like Météo Suisse did with the COSMO model. I don't think Windy can have a similar approach on a global scale, it is necessarily much more simplistic. -
@idefix37 Im not a native english so im not sure i got the end of your message 100% si i will rephrase
With the opening of more data are now available.--AROME-PI is a nowcasting model with the same domain as AROME-FR it uses the last available run of AROME-FR to get the initial info with the in situ info from radars ground station and plane + radiosondes but no satelite data is ingested data is ingested from H-10 to H+10 it has a 15 min step and runs all the way to H+6
Info in french HERE--PIAF is a Rain rate model it has a 5 min step runs every 5 min all the way to H+3 it uses the lastest available AROME-PI run and also uses PANTHERE radar image
it is a image that is corrected with all the rain gauge available to have a corrected RR over france
both are input
info (in french ) HEREi dont know if any are a good adition to Windy but as you guys are building a prediction section in the radar image it would be a good idea to add what is already run and accurate as it would only add value over france in the prediction section
