Click Save and Update Browser - this will re-grid and show data in Viewer Now you save your special View file: I already saved a copy under http://webapps.datafed.net/datafed.aspx?page=Giovanni/AIRNOW_Giovanni - loads all the views ----- youcan modify this and re-save it by File Save Page http://webapps.datafed.net/datafed.aspx?view=Giovanni/AIRNOW_Giovanni_map - loads only the map view
This will give you a 'Giovanni' page with your special settings. Now you can invoke this special map view service as:
http://webapps.datafed.net/datafed.aspx?view=Giovanni/AIRNOW_Giovanni_map
or with DateTime
Once you get this far, we can move on the get the 'Giovanni" map view in netCDF format. Kari will give us the URL for that.
