Choosing a dataset from the available list
As soon as you created a new project, you will be redirected to the data calendar page and since you have no dataset selected yet, the available dataset section will be opened automatically for you (you can do that manually by clicking Available Datasets menu on the bottom-left corner).
In the Available Datasets section, you will see all the datasets that you have access to. This includes your own datasets, public ones and ones that you were granted access to specifically.
In the list, you can click the dataset name to see the detail page of that dataset (see below for more information). You can read the information of that dataset and then click the Add button to start working with that dataset.
Once the dataset was added, that dataset will be removed from Available Datasets section and will be inserted to Selected Datasets section (you can only add one particular dataset once to a project).
You can add more than one dataset for your project, with a limit of 5 datasets per project.
If you click the dataset name in either the Selected Datasets or Available Datasets sections, a dataset detail window will be opened. It contains a lot of information regarding that particular dataset for example the availability over time, description, available fields, and other useful information.
Removing a dataset once selected
To remove a selected dataset, you have to open the dataset detail page by clicking the dataset name in the Available Datasets section and click the Remove button.
Currently, you can only do this if you don’t have any operations attached to the dataset you intend to remove. Once you have an operator applied to your dataset, you have to go to Operations page first and remove the operator node that is attached to the dataset first in order to delete the dataset (you might have to remove multiple operators if order to be able to delete the operator directly attached to the dataset).
