As part of security improvements, access to several data repositories on the ESA Dissemination Services, such as the Envisat MERIS and SMOS services, have changed from simple FTP to FTPS.

If you download data from the dissemination services using an FTP client, such as FileZilla, use the following settings to access via FTPS:

• Host: Enter the URL of the system (e.g. ftps://meris-ds.eo.esa.int for the MERIS service)
• Encryption: Select “Require implicit FTP over TLS”
• Logon Type: Select “Normal”
• User and Password: Enter your EO-Sign In account credentials

If you use a script to download data and have experienced issues following the transition to FTPS, we recommend using programs such as LFTP or WGET. 

Follow these examples of commands to download data using these programs: 

LFTP

Download a single file:

lftp -u 'user' -e "set ftp:ssl-force true; set ssl:verify-certificate no;set ftp:ssl-protect-data true; get /readme.txt; bye" ftps://meris-ds.eo.esa.int
Download a directory: 
lftp -u 'user' -e "set ftp:ssl-force true; set ssl:verify-certificate no;set ftp:ssl-protect-data true; mirror /MERIS/MER_FRS_1P/2/2002/0010; bye" ftps://meris-ds.eo.esa.int

Wget

Download a single file:

wget --ftps-implicit --no-check-certificate --ftp-user='XXXXXXXXX' --ftp-password='XXXXXXXXXX' ftps://smos-diss.eo.esa.int:990/SMOS/AUX_Dynamic/AUX_ECMWF_/2010/06/01/SM_REPR_AUX_ECMWF__20100601T232050_20100602T002730_400_001_3.zip
