    Drones join the campaign to validate Aeolus data

    In June and September 2022, the Askos component of the Joint Aeolus Tropical Atlantic Campaign (JATAC), organised by ESA and its international partners, was expanded with new ground-based, drone and radiosonde measurements. The main objective of this campaign was to calibrate and validate Aeolus satellite observations.

    Landsat 7 ETM + European and Mediterranean Countries Cloud Free Collection

    This dataset contains the cloud-free products from Landsat 7 Enhanced Thematic Mapper collection acquired over Europe, North Africa and middle East; for each scene only one product is selected, with the minimal cloud coverage. The Landsat 7 ETM+ scenes typically cover 185 x 170 km. A standard full scene is nominally centred on the intersection between a Path and Row (the actual image centre can vary by up to 100m). The data are system corrected.

    This dataset contains the cloud-free products from Landsat 5 Thematic Mapper collection acquired over Europe, North Africa and middle East; for each scene only one product is selected, with the minimal cloud coverage. The acquired Landsat TM scene covers approximately 183 x 172.8 km. A standard full scene is nominally centred on the intersection between a path and row (the actual image centre can vary by up to 100 m). The data are system corrected.

    PAZ ESA archive

    The PAZ ESA archive collection consists of PAZ Level 1 data previously requested by ESA supported projects over their areas of interest around the world and, as a consequence, the products are scattered and dispersed worldwide and in different time windows. The dataset regularly grows as ESA collects new products over the years. Available modes are: StripMap mode (SM): SSD less than 3 m for a scene 30 km x 50 km in single polarization or 15 km x 50 km in dual polarisation ScanSAR mode (SC): the scene is 100 x 150 km2, SSD less than 18 m in signle pol only Wide ScanSAR mode (WS): single polarisation only, with SS less than 40 m and scene size of 270 x 200 km2 Spotlight modes (SL): SSD less than 2 m for a scene 10 km x 10 km, both single and dual polarization are available High Resolution Spotlight mode (HS): in both single and dual polarisation, the scene is 10x5 km2, SSD less than 1 m Staring Spotlight mode (ST): SSD is 25 cm, the scene size is 4 x 4 km2, in single polarisation only.   The available geometric projections are: Single Look Slant Range Complex (SSC): single look product, no geocoding, no radiometric artifact included, the pixel spacing is equidistant in azimuth and in ground range  Multi Look Ground Range Detected (MGD): detected multi look product, simple polynomial slant-to-ground projection is performed in range, no image rotation to a map coordinate system is performed Geocoded Ellipsoid Corrected (GEC): multi look detected product, projected and re-sampled to the WGS84 reference ellipsoid with no terrain corrections Enhanced Ellipsoid Corrected (EEC): multi look detected product, projected and re-sampled to the WGS84 reference ellipsoid, the image distortions caused by varying terrain height are corrected using a DEM.   The following table summarises the offered product types.
