    Satellite data central to ocean monitoring

    Over 95% of Earth’s water is found in our oceans, and yet sadly, oceans are under stress from climate change and pollution. Monitoring our oceans is vital for Earth’s survival and satellites are the primary means of long-term and independent observation of our vast ocean bodies and their associated coastal zones.

    NovaSAR-1 new tasking

    NovaSAR-1 new acquisition data are available in two baseline acquisition modes: Stripmap – provides the highest resolution of 6 metres with up to 20 km swath selected from a 150 km field of regard, available in single polarisation. ScanSAR – has a 20 - 30 metre resolution and up to 150 km swath. Available in single polarisation. Within each of the baseline modes there are a variety of mode options that vary according to ground range resolution, incidence angles, swath width and the number of looks: Acquisition Mode Polarisation Resolution (m) Swath Width (km) Incidence Angles Number of Looks Stripmap Single: HH 6 20 16.0 – 25.38° 3 (1 range, 3 azimuth) 13 – 20 21.29 – 31.2° Single: VV 6 20 16.0 – 25.38° 3 (1 range, 3 azimuth) 13 – 20 21.29 – 31.2° ScanSAR Single: HH 20 100 15.0 - 24.66° 4 (2 range, 2 azimuth) 50 24.51 - 28.94° Single: VV 20 100 15.0 – 24.66° 4 (2 range, 2 azimuth) 50 24.51 - 28.94° Single: HH 30 150 11.29 – 25.93° 4 (2 range, 2 azimuth) 55 27.35 - 32.01° Single: VV 30 150 11.29 – 25.93° 4 (2 range, 2 azimuth) 55 27.35 - 32.01° NovaSAR-1 data are provided as a Level 2 (ARD) product as standard, but the accompanying Level 1 data may also be requested. Level 1 – delivered as reconstructed, unprocessed instrument data at full resolution. Level 2 (ARD) – delivered as a processed product with applied radiometric and geometric corrections i.e. orthorectification and spatial registration: Geocoded Ellipsoid Corrected (GEC) – Maritime and ocean applications Geocoded Terrain Corrected (GTC) – Land applications and change detection Where available, associated automatic identification system (AIS) data may be requested alongside the NovaSAR-1 data products.
