Event - Meeting
VH-RODA and CEOS SAR workshop
The workshop provided an open forum for the presentation and discussion of current status and future developments related to the calibration and validation of space borne very high-resolution SAR and optical sensors and data products.
Campaign
TerraSARSIM
The objectives of the TerraSAR SIM project were to quantify the impact of the time intervals between SAR acquisitions at different wavelengths on agricultural applications.

TerraSAR-X ESA archive
The TerraSAR-X ESA archive collection consists of TerraSAR-X and TanDEM-X 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. TerraSAR-X/TanDEM-X Image Products can be acquired in 6 image modes with flexible resolutions (from 0.25m to 40m) and scene sizes. Thanks to different polarimetric combinations and processing levels the delivered imagery can be tailored specifically to meet the requirements of the application. The following list delineates the characteristics of the SAR imaging modes that are disseminated under ESA Third Party Missions (TPM). StripMap (SM): Resolution 3 m, Scene size 30x50 km2 (up to 30x1650 km2) SpotLight (SL): Resolution 2 m, Scene size 10x10 km2 Staring SpotLight (ST): Resolution 0.25m, Scene size 4x3.7 km2 High Resolution SpotLight (HS): Resolution 1 m, Scene size 10x5 km2 ScanSAR (SC): Resolution 18 m, Scene size 100x150 km2 (up to 100x1650 km2) Wide ScanSAR (WS): Resolution 40 m, Scene size 270x200 km2 (up to 270x1500 km2) The following list briefly delineates the available processing levels for the TerraSAR-X dataset: SSC (Single Look Slant Range Complex) in DLR-defined COSAR binary format MGD (Multi Look Ground Range Detected) in GeoTiff format • GEC (Geocoded Ellipsoid Corrected) in GeoTiff format EEC (Enhanced Ellipsoid Corrected in GeoTiff format Spatial coverage: Check the spatial coverage of the collection on a map available on the Third Party Missions Dissemination Service. As per ESA policy, very high-resolution data over conflict areas cannot be provided.

Ship trails in the Bay of Biscay observed using PROBA-V imagery
Ship trails have been perceived as convincing evidence of aerosol-cloud interaction. Ship emissions have been proven to contribute by about 1.9% and 2.9% to the increase in the global total and fine-mode aerosol optical thickness (AOT) respectively over a five year period (Peters et al. 20212).

PV-LAC-COAST-SR-v1.1.pdf
In the frame of the PV-LAC project a prototype code has been developed, tested and validated for the atmospheric correction (A/C) and turbidity retrieval of PROBA-V data over turbid coastal areas.
Document - General Reference
PV-LAC-COAST-RBD-v1-1.pdf
The aim of this document is to make a critical review of the algorithms for TSM retrieval and atmospheric correction in turbid coastal waters, to identify the most suitable method (TSM and A/C method) for PROBA-V, to define the validation approach (including identification of the validation data and test sites) and to assess the utility and benefits of 100m coastal products through interaction with the user community.
