@bluesharp both links seem to work fine here, just checked them and they are working

@Mav-jp said in F4Wx – Real Weather Converter:
@Ahmed just make sure f4wx writes the correct version number in the header
Yep, it is still using the old version (5), as I haven’t had time to make any updates for a very long time. Can’t offer yet any ETA on any updates to use the new options (and also can’t think of any way of estimating fog altitude from available GRIB data, any ideas welcome by pm)

@Ahmed
The new fog altitude feature, added with version 4.6, interacts with the visibility maps: as currently the fog altitudes are zero at each generated FMAP; this involves that the visibility criteria are never applied…
from what I understand, it is difficult to get this dataif is there no possibility to extract fog altitude from real-world GRIB data, couldn’t we to apply a criteria scaled according to visibility data ?
Indeed, this is currently not being populated by F4Wx, as it needs to be updated to make avail of this new BMS feature. The issue I have seen, is that GRIB files from NOAA don’t contain enough data from NOAA to estimate these fog layers.
I have limited time, so I haven’t been able to do much research on how to estimate it from existing data. If anyone has any suggestions or even a basic ROT that can be used, I’d be more than happy to update F4Wx to use that.

RE: F4Wx – Real Weather Converter
I see no issue on my system.
If you are still having this issue, I suggest that you make sure that you are not blocking F4Wx on your firewall or something.

RE: F4Wx – Real Weather Converter
@MaxWaldorf This probably has to do with what I mention is not implemented yet and BMS is just filling for that. In any case I’d have to see the result. Hazy skies while still being clear of clouds are a thing irl.

RE: F4Wx – Real Weather Converter
Hi all,
I haven’t had any time to dedicate to F4Wx or even monitoring this thread lately and it will take probably a few months until I have, so thanks to those helping people resolve their questions and issues lately.
Just a quick bit of information: F4Wx works with BMS 4.36 without the need for any updates. There is only one new feature of the weather engine introduced in 4.36 that F4Wx doesn’t take advantage of, yet.
As stated by some, since 4.35 the “sync with real timezone” option shouldn’t be used and I’ll remove it on the next update.
Due to my lack of time to dedicate to this, it is my idea to release the source code and host a repository for F4Wx on github, as my contribution to the community and so that whoever wants to contribute can do it through forks and pull requests. I just want to refactor some of the ugly code from many years ago before I do this. But I hope to do that at some point this year.

RE: F4Wx – Real Weather Converter
Hi Ahmed,
could you please check this issue report https://bmsbugs.blu3wolf.com/view.php?id=206
I noticed something strange with the F4Wx fmap reading in BMS
thx
Hi,
If I understand correctly, the bug is that the fmap loads correctly into the mission and you get the correct visibility, but if you leave and reload the mission the visibility will be incorrect. If this is the case, it looks to be more of a BMS issue when saving/reloading that weather than a F4Wx specific issue (although may be something that happens only with F4Wx generated fmaps and not with other tool’s). If any BMS dev can shed some light about this I’d appreciate.
Regards

RE: F4Wx – Real Weather Converter
Does not work. “Error downloading file index.” Why so?
This is generally NOAA’s server connectivity issues so not much I can do about that. They have also been changing their directory structure and GRIB parameters quite a few times in the last months so it would help if it was more stable frankly… So far it is working now so I assume it was the former.
+100!
And please, dear Ahmed - would you take in consideration to add those other theaters released in these last days all, if you don’t mind and this won’t make you busy too much?Yeah absolutely. Can you guys reply with a list of the new theaters that are not yet in F4Wx? I don’t have much time right now to keep up to date with all new releases myself, but adding them to F4Wx takes a few minutes if you give me some links.

RE: F4Wx – Real Weather Converter
Added Taiwan preset as well through the auto-updater.

RE: F4Wx – Real Weather Converter
Nevada preset added and available on the built-in updater

RE: F4Wx – Real Weather Converter
Good morning, dear Ahmed.
As you sure know, Nevada theater for 4.35.1 has been released… we have a great theater back, it was time.
We were wondering if it would be added by you to your most useful utility’s theater list in the next future versions… for any use and help, here as follow are its coordinates (courtesy by NIL, who caught them out):
Min LAT: +33
Max LAT: +43
Left LON: -121
Right LON: -109
Time Zone: -9
Theater Size: 64Thanks in advance for your attention also, and with best regards.
Hi, Thanks I’ll take a look at it in the next days.
“Sync With Real Timezone” should be removed because now we talk in Zulu time
it brings some confusion…
You are right. I’ll make a note for the next update.

RE: F4Wx – Real Weather Converter
New update is available on the first post.
I released it as otherwise you guys have no functional version of F4Wx, but this is as beta as it can get. The changes to some of the parameters on the GRIB files meant that the cloud layer detection/conversion had to be completely re-written. I’ve been able to do only limited testing of how of an accurate representation of the real world cloud coverage it is depicting right now. If you find any significant mismatches, feel free to send me any feedback of inaccurate clouds, accompained by real world metar/satellite imagery for a given date/time, to further investigate.

RE: F4Wx – Real Weather Converter
Hi all,
NOAA changed the directory structure on their servers, meaning that F4Wx stopped working. I’ve already fixed that.
However, a more complex additional new issue, due to new data provided in the GRIBs, will require more investigation before I can release an update.
And yes, Grb2Fmap is not compatible with latest BMS releases.

RE: F4Wx – Real Weather Converter
Hi,
Sorry, not having much time to check the forum. I take note of the issues of the last week, although it seems to be working ok right now. 99.9% of the times these have been caused by NOAA’s grib filter, that the program is built around, being down, and are temporary.
If anyody can provide an alternate source of GRIB data I’m happy to add it as a seondary source for F4Wx, but so far I don’t know any and we fully depend on NOAA’s infrastructure.

RE: F4Wx – Real Weather Converter
Is that a F4Wx or a WC issue? I don’t understand the issue from your post. If this is F4Wx related please attach the particular files giving problems and/or steps to reproduce.

RE: F4Wx – Real Weather Converter
and so the “Sync with realtime” option zone is now useless
Yes, I overlooked that one and it is still syncing to local time (d’oh!). It would still have a use otherwise. Unless it is bothering people much, I’ll wait until I finish some other work before pushing an update to fix that.

RE: F4Wx – Real Weather Converter
Lets try it again
For your clouds photo comparison vs windy.com also bear in mind that GFS data contains several cloud layer data. F4Wx selects the most significative of this data and fits it to what the BMS weather engine allows to depict (and disregards the rest). And for the weather type selection it further takes into account some additional parameters, like precipitation, to select the most appropriate one for the general conditions in that particular cell. Thus, having some differences with windy.com that straight away paints all GFS data is something to be expected. The overall weather you get in the sim should still be a very good representation of the real weather at that particular point.
