ECMWF has adopted an open data policy, with the objective of expanding free and equitable access to high‑quality numerical weather prediction data for the global meteorological community. This shift supports the socio‑economic benefits of weather and climate information and aligns with WMO policies on international data exchange and capacity development for National Meteorological and Hydrological Services (NMHSs).
