See Brief request syntax to understand each keyword. |
We have created some request examples. You can see the explanation and then a link to the ECMWF Public Dataset web interface.
When click to the "ECMWF Public Dataset web interface" link, the values will be pre-selected. To see the script you have to use "View MARS Request" button.
