Notes:

• For contoured maps of recent data, go here.
• The 912x650 size works best for full page 8.5"x11.5" printing, if you select the landscape orientation using the "Properties" or "Preferences" option of the print window.
• North American archived data goes back as far as June 1957.
• Global archived data goes back as far as 1999.
• Data above 100 hPa begin in 1999.
