Search here to find SAR scene data in the UNAVCO WInSAR archive, and ALOS scenes in the ASF 'Data Pool' (actual data is not at UNAVCO).

Use the Numeric Selector for ERS, Envisat and ALOS scenes. Use the Map Selector to find only ERS scenes.
From the search results table you can download data files from the UNAVCO archive with your web browser (one scene at a time), and find file names in the ASF Data Pool. For instructions, see Help. This search facility now finds scenes in multiframe Envisat strips.

Map Selector
Only ERS scenes are shown on this map. (It works by ERS track and frame numbers) Do a mouse drag to draw a rubber-band box around locations to select. The selected points change color. ERS track and frame numbers are entered in the Numeric Selector. To zoom, zoom in or out with the zoom buttons. To pan (shift view), click the "Shift View" button (it dims), and drag the mouse pointer. To select points in the displayed map, click the "Select Region" button (it dims) and do mouse drag to make the rubber-band box.
Then click the "Submit Search" button at bottom of this page..

Note: If you don't see the applet running above, Java Plug-in needs to be installed. This happens automatically when you install the J2SE JRE or SDK. We strongly recommend that you install the latest version; at least 1.3.1 is required for the Map Applet. You can find more information in the Java Plug-in home page.

Selecting points should automatically fill in the proper search parameters (the track and frame ranges) on the numeric form. In some browsers (notably Safari) you may not see the form update until you click outside the map.

If you are running IE 5 on a Mac, the Map Applet may not work even if you do have Java Plug-in. If so, use Safari instead, or simply enter the track and frame ranges manually.
