To use the COVE tool,
1. Click on an instrument in the Missions and Instruments list in the upper left panel. For this example, we'll use AMSR-E, an instrument on the Aqua satellite.
2. You can change the time span if you like, by modifying the date field, or clicking the
icon and selecting a different date. For this example, we will use the default start and end dates.
3. Click the "Add Ground Swath". After some calculation (usually 5-20 seconds), the ground swath for AMSR-E will appear on the globe. You can rotate this globe by dragging with your mouse and you can zoom in and out with the mouse wheel. If you click on a segment of a ground swath, COVE will display a pop-up bubble with more details.
4. You can add more ground swaths to the globe at any time by selecting the instrument you desire and clicking "Add Ground Swath."
5. If you select more than one instrument (by shift-clicking or ctrl-clicking), then you can display the coinicidence of the instruments - that is, regions that were accessible by both instruments within a short time period. This time period, called the "lapse time", is set to 3 hours by default. You can change the lapse time by clicking on the calendar button
in the cart.
6. You can remove ground swaths and coincidence plots that you don't wish to see anymore by clicking on the
icon in the corresponding item in the cart.
