EARS comprises 10 separate data services that aim to provide users with high timeliness regional data from polar orbiting meteorological satellites, in support of Numerical Weather Prediction (NWP) and Nowcasting (NWC) applications.

This is achieved through a network of Direct Broadcast stations receiving and processing data and redistribution of products to users in near-real time.

An overview of the stations and satellites supporting each Regional Service is provided in the tables below.
