How to use; JRA-55 Atlas instructions
The JRA-55 Atlas provides climate maps for more than 70 meteorological variables in the seven categories listed below "Display climate map" in the right-hand menu.
1. Category SelectionChoose a category from the right-hand menu. First-time users may wish to try "Surface climatology" to start.
2. Variable and color selectionAfter selecting a category, choose a variable, color and vertical level (only for isobaric and isentropic climatologies) from the upper menu ①. Once the figures appear on the screen, choose a month or season using the lower buttons ②.
To see seasonal changes, use the left or right keyboard arrow "← →" or click the arrow icon that appears when the cursor is placed over the figure. Each arrow key action or click toggles to the previous or next month/season.

Choose a month/season from the "select month or season to download" menu and click "png figure", "eps figure" or "text data" below it. It should be noted that the month/season chosen here does not correspond to the figure on the screen.
