Windy missed radiosonde for days tho data posted to NOAA archive

@Filip_K BTW, what about those neighboring Indonesian airports like Rania, Medan, Padang, PangkalPinang, and Pontianak? Do you see a time when Windy will report their daily radiosondes?

Unfortunately, NOAA radiosonde archive is currently not on our to-do list, so I can't give You any specific date.

Also, I quickly tried getting the data from the archive and it seems it has changed. Link to the root of the archive (https://www.ncei.noaa.gov/data/integrated-global-radiosonde-archive/access/data-y2d/) doesn't seem to work anymore, although link to specific file (like https://www.ncei.noaa.gov/data/integrated-global-radiosonde-archive/access/data-y2d/MYM00048650-data-beg2021.txt.zip) does work for me.

Does it work for You?

@Filip_K NOAA

(1) Radiosonde archival data retrieval still works, thru the siphon package as follows (in Python):

from siphon.simplewebservice.igra2 import IGRAUpperAir
# Make the request. IGRAUpperAir returns a dataframe containing the sounding data and
# a dataframe with station metadata from the sounding header.
df0, header = IGRAUpperAir.request_data(date, stationCode)

Note that the archive holds data only up to roughly 2 days ago. So, when asked for today or yesterday's data, it returns error.

(2) Indonesian airport radiosondes have been displaying on Windy since the day after I asked, and has been consistently doing so. It's great, though only in fm35 format (fewer levels of altitude than fm94, shown for Malaysian & Singapore airports).

(3) But Philippines still no luck.

(4) Windy used to carry 2 weeks of archival radiosonde data and it was really useful for looking up day-to-day changes whenever the weather changes drastically. But since the last major change on Windy, it's been gone. Can we bring it back?

@hangInThere
(1) great, thank You

(2) we are not filtering fm94 out so most likely only fm35 comes through data feeds we have

(3) I do see some ascents from Philippines, although quite old and sparse:

(4) That is still available. Here is an example of Indonesian Surabaya:

(4) Ah, I see, it's still there in desktop browser. I just checked again, not on mobile browser nor Android app.

@Filip_K Now the archival radiosonde data is gone from the desktop Windy too! Can you please restore it? And on the mobile Windy as well?

hangInThere

@Filip_K It just came back. Can you do the same for the mobile Windy?

Filip_K

@hangInThere
the issue with desktop is that sometimes the ascents are loaded, sometimes not. It is most likely a bug in the frontend. I've forwarded it to my colleges.

As for mobile browser and app, I believe there has never been list of historical ascents available and as far as I know, it is not planned.

@Filip_K The mobile app always had the 14-day archival ascent data. It's what I had been using always, until the major revision of Windy Android app in 2024 wiped it away. So, if you look into your Android app before that major revision, the codes must be reusable. Try 'grep ascents -r' from the top of the code directories.

@hangInThere
It seems there is a bug that prevents historical ascents from being displayed. It should be fixed in the near future. Thank You for pointing it out.
