    ESA's improved Earth system data records: what is in store for the future?

    Fundamental Data Records (FDRs) are instrumental in advancing our understanding of Earth systems and for addressing societal challenges effectively. These long-term records contain uncertainty-quantified, calibrated and geo-located multi-instrument/multi-platform satellite sensor data spanning several decades to support climate-related applications.

    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.

    ICEYE ESA archive collection now available to users

    ICEYE ESA archive collection is now available worldwide through ESA’s Third Party Missions programme. The ESA archive collections consist of products requested by ESA-supported projects worldwide, and, therefore, the products are scattered and dispersed over the territory in different time windows. The datasets regularly grow as ESA collects new products over the years.

    ICEYE ESA archive

    The ICEYE ESA archive collection consists of ICEYE Level 1 products requested by ESA supported projects over their areas of interest around the world. The dataset regularly grows as ESA collects new products over the years. Three different modes are available: Spot: With a slant resolution of 50 cm in range by 25 cm in azimuth that translated into the ground generates a ground resolution of 1 m over an area of 5 km x 5 km. Due to multi-looking, speckle noise is significantly reduced Strip: The ground swath is 30 x 50 km2 and the ground range resolution is 3 m Scan: A large area (100 km x 100 km is acquired with ground resolution of 15 m). Two different processing levels: Single Look Complex (SLC): Level 1A geo-referenced product and stored in the satellite's native image acquisition geometry (the slant imaging plane) Ground Range Detected (GRD): Level 1B product; detected, multi-looked and projected to ground range using an Earth ellipsoid model; the image coordinates are oriented along the flight direction and along the ground range; no image rotation to a map coordinate system is performed, interpolation artefacts not introduced. The following table defines the offered product types: EO-SIP Product Type Mode Processing level XN_SM__SLC Strip Single Look Complex (SLC) - Level 1A XN_SM__GRD Strip Ground Range Detected (GRD) - Level 1B XN_SL__SLC Spot Single Look Complex (SLC) - Level 1A XN_SL__GRD Spot Ground Range Detected (GRD) - Level 1B XN_SR__GRD Scan Ground Range Detected (GRD) - Level 1B As per ESA policy, very high-resolution data over conflict areas cannot be provided.
