================================================================================ Satellite\RADARSAT-2\readme_RADARSAT-2.txt RADARSAT-2 Data Description Roland Romeiser - rromeiser@miami.edu - 2020-2021 ### Satellite\RADARSAT-2\Images\ ### This folder contains quicklook (low quality) versions of two SAR images of the test area acquired by RADARSAT-2 in September 2017. The images are provided as PNG files embedded in KMZ files, so they can be viewed in Google Earth. Alternatively, the PNG files can be extracted by opening the KMZ files in 7-Zip or a similar software tool. The quicklook images should be used for orientation only. Any use of the SAR images for quantitative analysis or for figures in publications or presentations should be based on the full-resolution data, which are provided at about 6 m / 2 m resolution, while the data you see here have been reduced to about 160 m / 50 m, for 20170908T141231_RS2 / 20170925T020027_RS2, respectively. The full- resolution data will also include detailed information on incidence angles, calibration constants, etc. RADARSAT-2 Data and Products (C) MacDONALD, DETTWILER AND ASSOCIATES LTD. 2017. All Rights Reserved. RADARSAT is an official mark of the Canadian Space Agency. Due to copyright protection, we cannot include the original data in this project data archive. The two images were acquired in Wide Fine / Wide Ultra-Fine Mode, VV. Archive structure: The archive Images_Preview.tar.gz contains the KMZ files. The KMZ file name format is YYYYMMDDTHHMMSS_RS2.kmz, where dates and times are start times of the SAR image acquisitions.

Graber (Co-PI) - hgraber@cstars.miami.edu ### Satellite\RADARSAT-2\IntWaves_CSTARS\ ### This folder contains shapes of internal wave signatures itentified in two RADARSAT-2 SAR images of the test area acquired by CSTARS, University of Miami, in September - October 2017. The internal wave shapes are provided as sets of shapefiles in ArcGIS shapefile format. These files can be opened in ArcGIS as well as Google Earth. Archive structure: The archive IntWaves_CSTARS.tar.gz contains the shapefile sets, one set per image in a separate folder. The folder name format is YYYYMMDDTHHMMSS_RSAT2_IntWaves_CSTARS, where dates and times are start times of the SAR image acquisitions. All dates and times are given in UTC, not local time.

Graber (Co-PI) - hgraber@cstars.miami.edu ### Satellite\RADARSAT-2\Winds_CSTARS\ ### This folder contains wind fields derived from two RADARSAT-2 SAR images of the test area acquired by CSTARS, University of Miami, in September 2017. The wind fields are provided as NetCDF files containing 10 m equivalent neutral winds on a 1000 m × 1000 m grid. They were derived from the SAR images using an algorithm developed at CSTARS. Higher resolution winds are available on request. Archive structure: The archive Winds_CSTARS.tar.gz contains the actual NetCDF files; Winds_CSTARS_Preview.tar.gz contains corresponding KMZ files for a quick visualization of the wind fields in Google Earth. The file name format is YYYYMMDDTHHMMSS_RSAT2_Winds_CSTARS.nc / YYYYMMDDTHHMMSS_RSAT2_Winds_CSTARS.kmz, where dates and times are start times of the SAR image acquisitions. All dates and times are given in UTC, not local time. Variables in the NetCDF files: lat = geographical latitude (decimal degrees) lon = geographical longitude (decimal degrees) eastward_wind = eastward component of wind u10 northward_wind = northward component of wind u10 eastward_wind and northward_wind have been set to NaN over land.
