Processor: Sentinel-1: SLC Coherence (6 days)

Note: This processor is identical to the Sentinel-1: SLC Coherence (12 days) processor but requires corresponding pairs of datasets that are acquired within a temporal baseline of six days. Thus, it can only be applied to datasets acquired before the loss of Sentinel-1B (23 December 2021). The processor is intended to be useful again after the launch of Sentinel-1C.

The Sentinel-1: SLC Coherence (6 days) processor for polarimetric Sentinel-1 L1 SLC input data generates a Sentinel-1 Level 2 product describing the coherence of a pair of images 12 days apart. Concurrently, a terrain-correction (using DEM) is performed. The coherence product is often also referred to as Sentinel-1 L2 CARD-COH12 product. This processor provided by the Joint Research Centre is based on a GPT graph that can be run with ESA SNAP.

The Sentinel-1: SLC Coherence (6 days) processor is pre-configured and can be easily applied by registered users to any Sentinel-1 L1 SLC data on individual demand via the CODE-DE Data Explorer.

Processor details

Input data:
- Sentinel-1 L1 SLC IW (Master Image)
Other data used for processing:
- A data sets acquired 6days before the master image and with the same orbit and footprint (slave images)
- Precise orbit information from ESA
- Copernicus DEM (GLO-30)
Methodology: Detailed information can be found in the links below

Access and use

Depending on the environment and intended use, there are the following possibilities to execute the processing:

EO Browser: -
Data Explorer:
- Data Catalogue: CODE-DE or CREODIAS
- Search and select required Sentinel-1 L1 SLC input data -> Add to Workspace
- Go to Workspace - > Select required datasets and Add to processing center -> Go to Processing center
