  • Fundamental Data Records for Radiometry [MWR_FDR___]

    This dataset is a Fundamental Data Record (FDR) resulting from the ESA FDR4ALT project. The Fundamental Data Record for Radiometry V1 products contain intercalibrated Top of the Atmosphere brightness temperatures at 23.8 and 36.5 GHz. The collection covers data for the ERS-1, ERS-2 and Envisat missions, and is built upon a new processing of Level 0 data, incorporating numerous improvements in terms of algorithms, flagging procedures, and corrections. Compared to existing datasets, the Radiometry FDR demonstrates notable improvements in several aspects: New solutions for instrumental effects (ERS Reflector loss, Skyhorn, and Sidelobe corrections) Native sampling rate of 7Hz with enhanced coverage The FDR4ALT products are available in NetCDF format. Free standard tools for reading NetCDF data can be used. Information for expert altimetry users is also available in a dedicated NetCDF group within the products. Please consult the FDR4ALT Product User Guide before using the data. The FDR4ALT datasets represent the new reference data for the ERS/Envisat altimetry missions, superseding any previous mission data. Users are strongly encouraged to make use of these datasets for optimal results.

  • Ensuring soil moisture data quality with reference measurements

    ESA is taking steps to verify the accuracy of soil moisture estimation with the Fiducial Reference Measurements for Soil Moisture (FRM4SM) project and a new version of the Quality Assurance for Soil Moisture (QA4SM) service.

  • Announcement of Opportunity for NovaSAR-1

    ESA is launching an Announcement of Opportunity for the international scientific community to access data from the NovaSAR-1 mission for science and EO-based applications development.

  • NovaSAR-1

    Launched on 16 September 2018, NovaSAR-1 features an S-band synthetic aperture radar (SAR) instrument offering a variety of modes with different resolutions and swath widths.

  • 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.
