3.1 Getting the data

GOMOS higher-level products are routinely disseminated to the users.

GOMOS Level1b products are available on request to the EO Helpdesk (e-mail address: EOHelp@esa.int).

GOMOS Level2 products (atmospheric and constituent profiles and near-real time products) are available for the whole mission on specific ftp servers as detailed below (for information on passwords, please contact the EO Helpdesk: EOHelp@esa.int).

Consolidated level2 products GOM_NL__2P:

The consolidated products GOM_NL__2P for dates after 23 July 2006 are available at D-PAC ftp server:

 ftp://gomo2usr@ftp-ops.de.envisat.esa.int.

They are made available about three weeks after the measurement time (one tar file of GOMOS products per day).

Reprocessed level2 products GOM_NL__2P:

The reprocessed products GOM_NL__2P for dates between 26 August 2002 and 4 July 2006 are available also at D-PAC ftp server: ftp://gomo2usr@ftp-ops.de.envisat.esa.int.

Near Real Time level2 products GOM_RR__2P:

The near-real time products may be downloaded from the servers:

ftp://gomosusr@oa-es.eo.esa.int (for ESRIN data)

and ftp://gomosusr@oa-ks.eo.esa.int (for Kiruna data).

They are made available usually about three hours after the measurement time and for about 7 days (they are then stored in archives).

All Level2 data (reprocessed, NRT and consolidated) are generated with the same version of GOMOS processor (IPF 5.00, made operational in August 2006). Some datasets reprocessed with a previous version of the prototype (see Appendix B of this document for details) are also available (measurements for 2003 and for the period between March and December 2004) at D-PAC ftp server.
