As of 27-04-2026, the datasets uwcw_extra_lv_ha43_nl_2km/1.0 and uwcw_extra_ha43_bess_0p05deg/1.0 have been deprecated. As of 30-06-2026 the datasets will no longer receive updates. You are advised to migrate for the Dutch domain to the new forecast dataset uwcw-ha-det-nl-s1/1.0, which includes common deterministic weather forecast parameters from the HARMONIE model. For the Caribbean domain, you are advised to use the harmonie_arome_cy43_bes/1.0 dataset.
These datasets are being phased out due to low user adoption and the high cost of upkeep. The alternative datasets contain a more general list of model parameters such as wind, temperature and precipitation, excluding the aviation specific parameters.
