EARS System

the EARS system is a Eumetsat project for data retransmission. 'EARS' means 'Eumetsat Advanced Retransmission Service'.

The object of the EARS system is to provide the European meteorological community with sounder data covering data-sparse areas, within 30 minutes of the instrument observations.

EARS comprises three separate polar satellite instrument data services:

  • the existing EARS-ATOVS;
  • the EARS-AVHRR;
  • and the pilot EARS-ASCAT.

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