Hi @堀田遼介, we're currently evaluating models from JMA and will most likely add at least one of them during this year

@Filip_K
Thank you for replying. I'm from Japan, so I'm glad that JMA's model will be expected to be adopted.

@堀田遼介
Which JMA models would you personally like to see added? We're thinking of adding LSM and most likely MSM or GSM

LSM seems the best model focusing this area.

With 2km resolution but 10h forecast only, with 24 runs per day !

MSM with 5km resolution could be an alternative for longer forecast.

The domains of these 2 models seems quite similar.

Indeed, some answers from the thread you mention (like adding Swiss model), didn't make much sense...

Regarding LSM, we have information from JMA that it should be 18h long from March 2024, which would make it much more useful than current 10h.

@Filip_K All models are usefil, but GSM and MSM is popular in Japanese weather company, and LFM is rarely used.
