Data needed for March 2023

Post by santoenzo »

Mrs, Mr,

I'm in a French laboratory working on marin aerosol dynamics in Belle-île en Mer (47.29N ; 3.222 W). I'm currently working with March 2023 data, and to success I need to know backward trajectories of wind during this period. However, trying with the GFS model, the only periods available are for June 2023. So I wonder if it was possible to get the March 2023 data, especially for the 03/08 at 3:30PM, the 03/13 at 08:00AM, and the 03/21 at 10:00AM.

Thanks you for your time,
French regards

If you are using HYSPLIT online on our READY server, choose the "Compute archive trajectories" option instead of the "Compute forecast trajectories" option. ARL has been archiving GFS 1/4-degree data for HYSPLIT since June 2019. Files for March 2023 are in the archive.
