RSS processed Sentinel-1A data for the analysis of water variations on Poyang Lake

The ESA Research & Service Support contributed to the analysis of Poyang Lake seasonal water variations by supporting the processing of related Sentinel-1A products and making available the required computing resources (RSS CloudToolbox).

A total of 71 Sentinel-1A IW SLC products (relative orbit number 40) acquired from June 2015 to May 2016 have been processed with the Sentinel Application Platform (SNAP) to compute all the possible 12-day interferometric coherence maps. More than 318 GB of data were processed with a customised processing chain to produce the desired results.

The images were calibrated in order to provide 3-band data combination (Sigma0_VV, Sigma0_VH and coherence) to create the final false colours video showing Poyang Lake water surface evolution in a news about ESA-China Dragon Cooperation Programme recently published on the ESA website: ESA’s Dragon cooperation with China extended to 2020
