First Metop-C IASI Spectrum

The IASI Level 1 data from Metop-C have been successfully validated and have operational quality.

Product Validation Report

The IASI Level 1C data, both the full spectral samples and the reduced spectral samples, as well as the Level 1 Principal Component Scores will be distributed on EUMETCast Europe:

  • On 1 July, they will be available on the High Volume Service Transponder 1 (HVS-1):
    • Channel: E1H-EPS-11
    • Multicast address: 224.223.223.12
    • PID: 600
  • From 2 July, they will be available on the Basic Service
    • Channel: EPS-11
    • Multicast address: 224.223.222.240:7022
    • PID: 500

(please see: https://www.eumetsat.int/website/home/News/DAT_4411829.html)

They will also be distributed on EUMETCast Terrestrial:

Channel: T01-EPS-C-11
Multicast address: 232.223.222.14

Example filenames:

IASI L1C:
W_XX-EUMETSAT-Darmstadt,SOUNDING+SATELLITE,METOPC+IASI_C_EUMP_20190610120856_02621_eps_t_l1.bin

IASI Principal Component Scores:
W_XX-EUMETSAT-Darmstadt,SOUNDING+SATELLITE,METOPC+IASI_C_EUMP_20190610120856_02621_eps_t_pcs_l1.bin

Note: When the Metop-C satellite is declared ‘secondary operational’ on 3 July 2019, ‘_C_’ in the filename will become ‘_O_’.
