No SIGMETs

Hi Hardy,

looks like you've been hit by NOAAs unannounced modifications to the aviationweather.gov site as well. SIGMET downloads are no longer working for PSX either I'm afraid.

I'm looking for a replacement, if I find one I'll let you know - would appreciate the same in return.

Thanks

Balt

Just FYI, they officially state that SIGMET data dissemination has been discontinued. Only available through the graphical interface now. A coding nightmare to try and scrape.

I cut and paste the SIGMETS for my flights from my Simbrief flight plans. This way I get the SIGMETS that were relevant to my trip as opposed to the worldwide coverage that Hardy provided.

Cover the data as per https://aviationweather.gov/data/api/

And the Data Server files at the bottom look interesting, too:
"designed for maximum compatibility with the previous Text Data Server".

Is there any way to make an https link string with API parameters that will cause their server to generate a SIGMET text?

Jeroen Hoppenbrouwers

The example on the page spits out stuff once I fill in a begin and end time.

https://aviationweather.gov/cgi-bin/data/dataserver.php?requestType=retrieve&dataSource=airsigmets&startTime=20231018_1800&endTime=20231018_2000&format=csv

I don't know whether you mean this with "SIGMET text". It obviously isn't human readable.

Balt

Thanks Hoppie, that's very useful! On the data API translation page, they actually state SIGMET: discontinued.

Hardy, I think you can simply parse the returned SIGMET text as per Hoppies sample call above and read the first field from the comma separated lines it spits out, those are the SIGMETs in raw text as we used to get.

Just checked Simbrief and their flight plans are generating current SIGMETS.

Thanks for the tip, Hoppie.

Just noticed it should be "isigmet" instead of "airsigmets":

https://aviationweather.gov/api/data/isigmet?region=asia&date=20231019_1300



But it's not a CSV file.

Actually, Gary showed the link already:

Cover the data as per https://aviationweather.gov/data/api/

I think when no parameter is added, the file will cover the entire world at the current time.

Well, and "isigmet" exludes the USA, so I still need to add "airsigmets" for the US and parse the CSV.

The new SIGMET URLs are now implemented in PSX version 10.172:

Thanks for this Hardy...its so frustrating that these sources keep changing their source codes.

All the best

NOAA's data has actually been available at the same URL for >8 years if memory serves.
