Hi everyone,
I’m currently having an issue processing Sentinel-1A GRD images using Terrain Correction with SRTM90. Every time I run the process, it fails with an error related to downloading SRTM DEM packages. It shows that it cannot be found when accessed from the browser.
I’ve tried changing the DEM URL to alternatives that were suggested in previous topics, such as:

Unfortunately, neither of these URL’s works. The same error occurs for every image I try to process. I am using SRTM 3 second as the DEM name with library snap 12.0.

Here is a link shown in the screenshot.

Thank you in advance for your help!.
Thanks.

SRTM data is not available globally. When SNAP attempts to download SRTM tiles for areas where they are not available, the download will fail. SNAP will then skip the unavailable tiles and continue processing.

To avoid this issue, we recommend using the Copernicus DEM instead, which provides coverage for your areas of interest.
