The Climate Branch iCalendar is compatible with Apple's iCal
and other applications that can read V-Card formatted calendar
files. There are two different ways you can go about downloading
this calendar.
Method 1
You can 'subscribe'
to the Climate calendar and automatically update it regularly
automatically. First, select Calendar->Subscribe... from
the menu bar (alternatively you can hit Option+Apple+S).
A Dialog box will open up. In the Calendar URL field,
paste this url: http://climate.gsfc.nasa.gov/ical/climate.ics
You can optionally choose to automatically update this calendar
every 15 minutes, every hour, every day, or once a week (use
the checkbox and pull-down list right below the URL field).
You can leave the "Remove Alarms" and "Remove To-Do Items"
checked if you want, but the Climate calendar doesn't use
those features. When you're ready, hit Subscribe.
Method 2
To download the calendar, use
the link below. You may have to right-click (or option-click)
and choose "Download Link
to Disk". When the download is complete, open up iCal
and, from the menu bar, chose "File"->
"Import". A new window will open propting you for
the type of calendar to import. Make sure 'Import an iCal
file' is selected before you hit the 'Import' button. A file
dialog will open where you will need to navigate to where
you saved the 'climate.ics' file. Once you have located the
'climate.ics', highlight it and click the 'Import' button.
The Climate Branch calendar events will then be imported into
iCal.
The calendar file is updated the minute the calendar on the
Climate Branch web-site. If you're going to download this often,
it's probably a good idea to delete the old climate calendar
in iCal before you import the new one.
