The Regional Data Services are provided by the EUMETSAT Advanced Retransmission Service (EARS), a network of Advanced High Resolution Picture Transmission (AHRPT) reception stations.

The EUMETSAT Advanced Retransmission Service (EARS) comprises nine separate data services: EARS-ASCAT, EARS-ATOVS, EARS-AVHRR, EARS-IASI, EARS-NWC, EARS-ATMS, EARS-CrIS, EARS-VIIRS and EARS-VASS.

They 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.

Satellites and instruments supported by EARS

Each of the EARS services retransmits observations from an instrument, or an instrument group, and aims to provide a homogeneous service across the NOAA, Metop and FY3 polar orbiting satellite platforms.

The satellites and instruments supported by EARS are as follows:

EARS Service		Satellite Series and Instruments
		NOAA NN’: NOAA18 & 19	Metop: Metop-A & B	Metop: Metop-C	NOAA JPSS: Suomi-NPP & NOAA-20	FY-3: FY-3C	FY-3: FY-3D
