Upcoming changes to Barents-2.5km EPS file production Sep 1, 2025 08:00-08:05 CEST

September 1st 2025 we will terminate the production of the barents_eps_*T*Z.nc files (four times a day, 6 members) and their accompanying mean files barents_mean_*T*Z.nc. These are replaced with NCML files:
- for each bulletin (four times a day, 6 members) : barents2500_his_sfc_*T*Z_ens_96h.ncml
- for the full ensemble (daily, 24 members) : barents2500_his_sfc_*_ens_96h.ncml

Additionally, we now produce a new mean based on all 24 members as well as the accompanying spread (standard deviation):
- barents2500_his_sfc_*_ensmean_96h.nc
- barents2500_his_sfc_*_ensstd_96h.nc

Files based on the full ensemble are available after all members have been processed, typically early the following day. All updates regard surface fields from Barents-2.5km EPS, and full depth fields are not affected by this change.

We have parallel production of the files, and will continue until September 1st 2025.

NCML file from latest run :
https://thredds.met.no/thredds/catalog/fou-hi/barents_eps_surface/catalog.html
NCML files from each run + NCML file for all members + EPS mean file + EPS spread file : https://thredds.met.no/thredds/catalog/fou-hi/barents_eps_surface/2025/04/01/catalog.html

Note: If you are already using NCML files from Barents EPS, please note the name change (we will continue parallel production with the old file name until September 1).

Norkyst (v2) stoppes 1. oktober 2025. Erstattes av ny Norkyst (v3) Oct 1, 2025 08:00-08:05 CEST

Dagens Norkyst-modell, versjon 2 (norkyst_v2), stoppes 1. oktober 2025, den vil erstattes av en oppgradert modell, versjon 3 (norkyst_v3). Norkyst_v3 har kjørt parallelt med norkyst_v2 siden 1. januar 2024, og modellresultater siden oppstart er tilgjengelig. Modellen kjører på et grid med samme projeksjon som norkyst_v2, men med større geografisk utstrekning og flere vertikale lag. Varslingslengden er samme som norkyst_v2, dvs. 120h.

Døgnmiddelfiler (AVG) vil ikke lenger produseres. Filer med timesverdier (HIS) som inneholder mange av de samme variablene som norkyst_v2 er tilgjengelig. Variabelnavn og dimensjonsnavn vil ikke endres, men følgende variabler er ikke lenger tilgjengelig:
- ubar
- vbar
- u (erstattet av u_eastward)
- v (erstattet av v_northward)
- tke
- Uwind (erstattet av Uwind_eastward)
- Vwind (erstattet av Vwind_northward)

Hardware failure
Resolved - We have now restored access to all datasets on thredds.met.no
Thanks for your patience during the long period of outage for the datasets affected.
Jul 3, 14:51 CEST
Update - Our crew is still working on the hardware problem with the vendor. We are thus not able to get the affected datasets online before they have corrected the root issue.
Many of our long timeseries (MEPS / AROME archives) are either shortened or entirely offline due to this problem.
Jul 2, 14:09 CEST
Identified - At 09:17UTC we encountered a hardware failure in our main data storage at MET, causing total outage until we failed over to reserve storage at 09:35UTC. We will continue in this mode until the hardware issue has been fixed.
A large number of datasets remain unavailable during this incidence, but our main forecast models are not affected.

Storage maintenance affecting data access on thredds.met.no ("storeB")
Completed - The maintenance is over. We have now restored access to all datasets and normal service.
Jun 30, 09:12 CEST
Update - From 10:15 UTC today we have restored access to those datasets that have been offline since the start of the maintenance. All high-availability datasets are still served from the reserve storage, as it takes a long time to get fully synchronized model forecasts on the main storage. We expect to return to normal state on Monday.
NOTE: Especially "MEPS Archive" and "AROME Arctic Archive" remains as short archives until Monday for the reason above.
Jun 27, 12:31 CEST
Update - Our team restored access to the reserve storage at 14:04 UTC. We will remain in the "normal" maintenance mode until further notice. Our most important weather forecasts shall be available as normal.
Our apologies for the long duration of the last anomaly.
Jun 26, 17:25 CEST
Update - We are currently experiencing an outage also of our reserve storage. It started at 13:10 UTC.
Our team is working to restore access.
Jun 26, 15:26 CEST
In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
Jun 24, 07:30 CEST
Scheduled - A storage maintenance is scheduled from June 24. until June 30. This will cause many datasets on thredds.met.no to be unavailable during the maintenance. It mostly affects "Users", "Projects" and long timeseries in archives, while our weather/ocean forecasts shall remain online.
In particular the long dataseries under "Weather forecasts" ("MEPS Archive/", "AROME Arctic archive/", "MET post-processed products/ Archive + Long term consistent", etc.) will remain unavailable during the maintenance.

thredds.met.no problems on June 20.
Resolved - This incident has been resolved.
Jun 24, 15:10 CEST
Investigating - During the end of the announced maintenance ("storeA") this week we have encountered severe problems with our main storage ("storeB"). These problems have resulted in several outages today (June 20.) before we eventually had to stop exposing the entire main storage system. We are now running only on the reserve storage, which has the consequence that our long timeseries archives are not available, as well as many datasets under "Users" and "Projects". It is not likely that access will be restored before the announced maintenance starts next week.
Please also note that we have not been able to get a smooth transition between the main and reserve storage systems, so for many datasets you will experience that there is a "hole" in timeseries or data files for this week, as we have not been able to transfer new files from the main storage into the reserve storage before the incidence today. This will also affect the most recent forecast models, so in the coming hours they may not be fully up-to-date. The state of each model depends on how frequently they are updated and when the last model run was performed.
Our apologies for the inconvenience this has for users.
