| Summary: | Since 1991, the European Space Agency's two ERS satellites have acquired microwave radar data of Antarctica. ERS data have been recorded by two receiving stations, one German, one Japanese. The former has allowed direct downlink and recording of high bit-rate, high resolution SAR image data of the Weddell and Seas during station campaigns. The latter has enabled some data from the Cosmonaut Sea and Indian Ocean quadrant to be collected. The Active Microwave Instrument on board ERS has two modes; SAR and When the is not an imaging mode, it allows data to be acquired when direct SAR is not possible, or when the receiving station is inoperable. advances in image generation from Scatterometer data enable medium-scale resolution images to be made from the 1 mode data during times when SAR images cannot be acquired. Together, these combined C-band microwave image data for the first time enable uninterrupted coverage of this geographic region at both high and medium-scale (-12 km) resolut. |
