These plots show one week of ERS-2 SAR planned acquisition, represented as empty squares. They are uploaded every Wednesday for the following week, from Monday to Sunday.

The Wind Scatterometer and the SAR Wave Mode are switched on by default for the orbit segments in which the SAR Image Mode is not switched on, unless descoping is required due to limited tape recorder capacity or ATSR-2 HR activity.
