New regional EARS-IASI Level 2 products soon on EUMETCast

The new regional EARS-IASI L2 products contain profiles of temperature and humidity derived from IASI, AMSU-A and MHS measurements from Metop-A and Metop-B, generated with the Piece-Wise Linear Regression-cube (PWLR3) algorithm.

They are available for all stations providing the EARS-IASI Level 1 service (currently: Athens, Kangerlussuaq, Lannion, Maspalomas, Moscow, Svalbard, Edmonton, Gander, Novosibirsk and Khabarovsk). The timeliness is expected to be better than 30 minutes for 95% of the data, except for the Canadian stations (currently: Edmonton and Gander) and FDES, Fast Dump Extract System (Svalbard, Metop-A).

The EARS-IASI L2 products are consistent with the global IASI L2 sounding products.

The filenames of the EARS-IASI L2 products follow the WMO naming convention:

W_XX-EUMETSAT-<station>,iasi,<satellite>+<station>_C_EUMS_<YYYYMMDDHHMISS>_IASI_PW3_02_M0x_<YYYYMMDDHHMISS>Z_<YYYYMMDDHHMISS>Z.hdf.bz2

where:
1st <YYYYMMDDHHMISS> is the creation time
2nd <YYYYMMDDHHMISS> is the data start time
3rd <YYYYMMDDHHMISS> is the data end time

M0x is the platform, either M01 or M02.

Example filename:

W_XX-EUMETSAT-sva,iasi,metopb+sva_C_EUMS_20171109100312_IASI_PW3_02_M01_20171109094042Z_20171109095537Z.hdf.bz2

The products will be distributed on EUMETCast Europe, on the same channel as the current EARS-IASI service: EUMETSAT Data Channel 1 (PID: 500, Multicast address: 224.223.222.1).

Users wishing to receive the EARS-IASI L2 products via EUMETCast should register via our Earth Observation Portal (EOP).
