Hi Raul,

The problem is that Aviso has moved distribution of MSLA sea surface height and error estimate products from their own server to the to the Copernicus Marine Environment Monitoring Service (CMEMS) server. CMEMS is a completely different organization than Aviso and the MGET tools for accessing Aviso’s server will not work with the CMEMS server.

We developed a completely new tool for accessing Aviso data at CMEMS. To use it, please:

1.    If you do not have MGET 0.8a66, please uninstall your existing version and install 0.8a66 from the MGET website.

2.    Go to the CMEMS website and register to access the Aviso data. The Aviso username and password will not work. You need to get a new username and password from CMEMS.

3.    Access the data with the new MGET tool in ArcToolbox à MGET à Data Products à CMEMS

Please note that only the Aviso MSLA “h” and “err” products are available from CMEMS (and not available from Aviso) and should be obtained with the new MGET tool. The other Aviso products, including all MADT products, and MSLA currents products (e.g. “u”, “v”, “eke”, etc.) still must be obtained from Aviso using the old MGET tool. This may change in a few months if Aviso moves more products to CMEMS, as they have said they intend to do.

Sorry for the confusion; we always have to catch up with what the data providers decide to do...

Best,

Jason

Dear Assistance Service of MGET,

My name is Raul Valente and I am a master's student in University of Porto, Portugal. In my thesis I will try to infer habitat preference of baleen whales species that cross Macaronesia during their inter-annual migrations. For that purpose I will need to have data from msla (delayed-time) since 2002. I used your tool called "Data Products", "AVISO", "DUACS 2014 Altimetry Products", "Create rasters for AVISO DUACS 2014 Altimetry Products", but unfortunately I have this error:

Failed to execute (AvisoDuacs2014GriddedProductCreateArcGISRasters).

With this in consideration,  I am writing for you because I would like to know, if you can tell me, why this message occurs, and how can I solve this problem in order to have my msla rasters.

Best regards,

Raul Valente
