Hostname of FTP server, specified as a string scalar or character vector.
The default port number for FTP servers is To specify an alternate port number for the connection, append a colon : and the port number to host. Typically, the hostname of the server starts with ftp , as in "ftp. However, this practice is a convention, not a technical requirement. Name of an authorized account on the FTP server, specified as a string scalar or character vector.
The FTP object sends username as plain text. Password for an authorized account, specified as a string scalar or character vector. The FTP object sends password as plain text. Specify optional comma-separated pairs of Name,Value arguments. Name is the argument name and Value is the corresponding value.
Name must appear inside quotes. This tool assumes a sphere with a radius of m. The NRT products are intended for users who need quick access to recent observations. They have a time step of 1 day and are updated on a continual basis. Aviso typically archives only the most recent year or two of NRT data. The DT products are intended for users who need a long term, more accurate time series.
The DT products incorporate more error corrections and other processing steps that improve accuracy. They are updated only every year or so but extend back to When they are updated, the entire time series is often reprocessed with improved algorithms. Starting in January , the DT products are available at a time step of 7 days weekly or 1 day daily. You may specify which temporal resolution you prefer. Note that, unlike many other oceanographic datasets, the weekly images are not created by aggregating the daily products together they are not produced taking mean of seven daily images, for example.
They are just a sparse selection of the daily images: every seventh daily image exactly matches a weekly image, pixel for pixel. Please see the Aviso documentation for more information. The DT-Ref products are based on a smaller number of satellites but are designed to provide a consistent level of accuracy throughout the entire time range of the data.
The DT-Upd products are based on more satellites and have variable accuracy depending on how many satellites were used on a given date. In general, the DT-Upd products are more accurate later in the time range, as more satellites were available.

After Aviso accepts your registration, they will email you a usernames and passwords for accessing Aviso datasets. The FTP username and password will not work. Please see the documentation for the Aviso Username parameter above for more information about the username and password parameters.
