Download CMEMS data issues

[rousseletL]

One of the most frequent issues causing SPASSO to stop running is the satellite data download not working. The SPASSO run is usually interrupted by this kind of error:

In the following, please find a check list to fix this error:

• Verify data availability on the CMEMS: the most common issue is that the data was not yet delivered on CMEMS server when trying to download.
• Check product id on CMEMS: the Copernicus Marine team "likes" changing the name of product id or add new products with new names.

Most of the time to fix the issue, one just need to:

• Change the product id name in the config_YOURCRUISE.ini file (for example phy_id = ) to match the one on Copernicus server:

• Change the date for the last available data in the config_YOURCRUISE.ini file by modifying the product date (for example phy_date = 0_ago to phy_date = 2_ago).
