With the interactive client below you can submit WCS requests and inspect results intuitively for Landsat 5, 7, 8 and Sentinel 2 coverages. Start with GetCapabilities to learn about the server's offerings; after that, you may proceed to DescribeCoverage to inspect a particular coverage, and finally GetCoverage - or you proceed directly to ProcessCoverages. Not sure about WCS requests? Learn more at the EarthServer webinars.
