Bonsoir;
Il semble qu'il y ait une mise à jour dans les répertoires de téléchargements de la NOAA ces prochains jours selon le message ci-dessous.
Tout sera fait pour que le chargement se passe toujours bien, au pire ça décalera une fois ou deux le temps qu'on retombe sur nos pieds.

Sujet: [NCEP.list.NOMADS-ftpprd] NOMADS/ftpprd NEWS for the week of March 17, 2021
Hello Users,
Apologies for the delay, here is the update for this week. Please note that the GFSv16, the LAMP/GLMP, and the NOS upgrades are all now planned for Monday, March 22, barring CWD. Also the notification about the upcoming changes to download limits for NOMADS & FTPPRD is linked below the Model Upgrades list, and will be effective April 20.
Upcoming Model Upgrades
GFS to version 16 - March 22
* GFSv16 will incorporate the wave model formerly known as wave_multi1. Because of this, the directory structure for its output will change from gfs.YYYYMMDD/CC/<files> to gfs.YYYYMMDD/CC/<component>/<files> where component is atmos or wave.
Data will be available on para NOMADS:
https://para.nomads.ncep.noaa.gov/pub/d ... /gfs/para/
https://para.nomads.ncep.noaa.gov/pub/d ... aport/gfs/
OpenDap also now available for particular subsets:
https://nomads.ncep.noaa.gov/dods/gfs_0p25_parafv3
https://nomads.ncep.noaa.gov/dods/wave/gfswave
SCN for upgrade:
https://www.weather.gov/media/notificat ... .0_aac.pdf
* GFSv16 will also have an effect on the timing of many models in the NCEP suite which are downstream of the GFS.
SCN for model timing changes:

Implementation date March 22, 2021
Upgrade of LAMP/GLMP
* Localized Aviation Model Output Statistics Program (LAMP) and Gridded LAMP (GLMP) will have new products in support of NBM (National Blend of Models) and other model changes.
Data will be available on para NOMADS as noted in the SCN.
SCN for upgrade (does not reflect new date):
https://www.weather.gov/media/notificat ... lmpaab.pdf
Implementation date March 22, 2021 (alongside GFSv16)
NOS implementing WCOFS and NGOFS2
* NOS is implementing two new grids - U.S. West Coast (WCOFS) and the upgraded northern Gulf of Mexico (NGOFS2).
* NGOFS, NEGOFS, and NWGOFS will be retired and their products (NetCDF output files and web products) will no longer be available after the upgrade. They are replaced by NGOFS2.
Data will be available on para NOMADS as noted in SCN.
SCN for upgrade:
https://www.weather.gov/media/notificat ... abdocx.pdf
Implementation date March 22, 2021
Upgrade of NWM and its post-processing application on IDP
* National Water Model is going to version 2.1, including new domains and products.
* Post processing application on IDP getting new products as well.
Data will be available on para NOMADS for NWMv1.2 and nomads for the post-processing application:
https://para.nomads.ncep.noaa.gov/pub/d ... /nwm/para/
https://nomads.ncep.noaa.gov/pub/data/n ... processed/
SCN for upgrade:
https://www.weather.gov/media/notificat ... 2_1aac.pdf
Implementation delayed to mid-April
Update of NBM - not full upgrade
* Updates to the National Blend of Models (NBM) guidance over the CONUS, OCONUS (Alaska, Hawaii, Puerto Rico) National Digital Forecast Database (NDFD) domains. Not a full upgrade of the model.
No para data will be made available.
SCN for upgrade:
https://www.weather.gov/media/notificat ... bm-qmd.pdf
Implementation date March 23, 2021
Upgrade of HIRES-W & HREF
* Upgrade includes replacing the Nonhydrostatic Multiscale Model on B-grid (NMMB) with a Finite Volume Cubed Sphere (FV3) model within the HIRESW system. This will increase the resolution to 3km from 3.2km, add 10 new vertical levels, and extend the forecast range from 48h to 60h.
Data will be available on para NOMADS end of March/early April.
SCN for upgrade: coming soon
Implementation date early May
*NEW*
Update to NOMADS/FTPPRD access limits
The National Centers for Environmental Prediction (NCEP) will be making a change to the user access policy for NOMADS and FTPPRD only. The usage policy will restrict individual user access to 120 hits/minute for only the websites listed above. All other website usage policies will remain as they are today. This policy is applied as a sum of hits per user Internet Protocol (IP) address across all sites listed above.
SCN for changes:
https://www.weather.gov/media/notificat ... hanges.pdf
Implementation date April 20, 2021
Recently Implemented Model Upgrades/Changes
Upgrade of ETSS and P-ETSS
SCN:
https://www.weather.gov/media/notificat ... tssaac.pdf
Implemented February 25, 2021
Public Information Statements (PNSs) of Note
Proposal to transition LAMP and GLMP products from TGFTP to NCEP web services
* Remove LAMP/GLMP products from TGFTP in favor of NOMADS/ftprd
PNS:
https://www.weather.gov/media/notificat ... nomads.pdf
New para nomads website coming
We are currently working to stand up a para NOMADS in our College Park data center to support NCO's transition from WCOSS to WCOSS2 in 2022. The URL is
https://para-nomads-cprk.ncep.noaa.gov/ but it is not serving active data at this time.
NOMADS upgrade coming
Within the next 12 months we will be upgrading the NOMADS website. Functionality should remain the same for existing scripts for grib filter, HTTPS downloads, and openDAP services, but the NOMADS front end webpage as well as the grib filter pages will see some changes. A test version of the upgraded website will be available before the upgrade, and an SCN advertising the changes will also be published and passed along here. There will be no changes to FTPPRD associated with this upgrade.
