How to access the data
You can access the JMA weather dataset from the DataEditor by using the merge table feature to join it to an existing table.
In order to join the weather dataset to an exisiting table, the original table must have a column of dates (DATE, DATETIME, or TIMESTAMP type). Date columns of the DATE type can only merge with daily weather data.
Licenses
You must purchase a license to access the JMA weather dataset. This is separate from licenses to use the DataEditor.
