Question Modèle Arpège-EU was created by ourasi
Bonjour,
En téléchargeant le modèle Arpège-EU de XYGRIB, je sélectionne la pression au niveau de la mer mais je suis incapable d'activer les isobars sur QTVLM. Même si la taille du fichier varie selon que je sélectionne ou non la pression, la pression n'apparait pas dans la section 'type de données" dans l'info sur le grib (CTRL+I) 
Est-ce que le problème serait donc plutot chez XYGRIB vu que ça n'arrive que pour ce modèle?
Merci.

Bonjour

Ca fonctionne chez moi (sur PC). Le fichier Arpege via Xygrib montre bien la pression (via info), et les lignes s'affichent à condition de choisir un pas suffisament fin ( 2hPa) compatible avec les différences de pression sur la zone.

Alors nouvel essai, et effectivement l'Arpege EU n'inclut pas la pression. Mais ça c'est un pb Xygrib ou directement Arpege probablement.

en tout cas avec ou sans la pression, les 2 fichiers font exactement  la meme taille donc la pression n est vraiment pas envoyée...

Hi everyone,
I emailed David at Skiron/Xygrib to share the issues noted in regards to both Arpège models: Global & EU.
We all do have our preferences & habits, so for the Arpège folks FYI below is David's reply.
Cheers.

David's reply:
Hi Bertrand,
All is well, and thank you for asking. I hope you are enjoying safe and happy sailing.
Regarding your questions
1. The global Arpege model was updated to 0.25 degree resolution and the output data set reflected this change as of February 2024. The file name given by the grib server still indicates 'arpege_p50', as this is hard-wired in XyGrib, and as no update is anticipated in the near future, the 'p_50' will remain.
2. The 3-day Grib files, in spite of the requests for 4 days, are a bug in the Grib server. It is on the list to fix.
3. The PRMSL should be included for Arpege EU. The bug is in the Grib server pre-processor. It is on the list to fix.
It will take a while, but I'll get to fixing the issue.
Best regards,
David
