How to access the data

You can access the JMA weather dataset from the Data Editor 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 Data Editor.

If you already have a license to use the Data Editor (including during the free trial), please request a quote from the settings tab of the Data Editor.

If you do not yet have a license to use the Data Editor, you must first purchase one. Then, please request a quote from the settings tab of the Data Editor.
