Sample decoded L0 data

All the documentation necessary to decode Sentinel-1 Level-0 products is providing in a single package. In addition to the documentation, it provides a sample of Level-0 product with the associated RAW decoded data in order to support the users.

Radiometric Re-compensation of Sentinel-1 SLC data

 

Changes of applied processing parameters during SAR data processing may impact the SAR data quality and can be a disturbing factor for long-term monitoring of radiometric features. Therefore, a re-compensation method has been proposed and verified which accounts for radiometric changes in particular due to different applied antenna patterns and processing gains. This method is published in an article called: Radiometric Re-Compensation of Sentinel-1 SAR Data Products for Artificial Biases due to Antenna Pattern Changes.

In order to help Sentinel-1 users to implement this method in their own software tools, two dedicated examples are presented in the publication containing intermediate results. For these examples two kind of SLC SAR data products are used:

  1. nominally produced products available at official data hub (https://dataspace.copernicus.eu/) 
  2. additional products re-processed with specific input data. These specific processed SAR products can be downloaded from the SAR MPC download area: case of 2017/07/11, and case of 2019/08/03.

The required ADF are available either:

Burst ID Maps

Sentinel-1 performs systematic acquisition of bursts in both IW and EW modes. The bursts overlap almost perfectly between different passes and are always located at the same place. With the deployment of the SAR processor S1-IPF 3.4, a new element has been added to the products annotations: the Burst ID, which should help the end user to identify a burst area of interest and facilitate searches. Now, we publish complementary auxiliary products, the Burst ID maps.

The maps have a validity that covers the entire time span of the mission and they are global, i.e., they include as well information where no SAR data is acquired. Each entry of the database contains information about burst and sub-swath IDs, relative orbit and burst polygon, and should allow for an easier link between a certain burst ID in a product and its corresponding geographic location.

The maps are public and can be freely downloaded here: [Burst ID Maps 2022-05-30]

The content is provided in sqlite3/spatialite binary (one per mode) and KMZ (one per mode and relative orbit number) formats. Additionally, a README file gives a description of the information provided by the maps, as well as information on the validation procedure and quality statistics.

For questions, please contact Copernicus EO Support (eosupport@copernicus.esa.int) addressing "SAR MPC". The questions will be forwarded to the SAR Mission Performance Cluster Service.
