I'd like to propose you to add this weather model to Windy.
HIRLAM (High Resolution Limited Area Model) is an operational synoptic and mesoscale weather prediction model. The model is developed by an international program formed by institutes from Sweden, Norway, Denmark, Iceland, the Netherlands, Ireland, Spain, Estonia and Lithuania. There is also close co-operation with France.
FMI provides its operational Hirlam model runs to be downloaded freely from AWS S3 bucket. The data is licenced by the Creative Commons Attribution 4.0 International license (CC BY 4.0).
The data is updated four times a day with analysis hours 00, 06, 12 and 18. Corresponding model runs are available roughly five hours after analysis time (~ after model run has started).
