You can download InSAR data from these websites:

https://scihub.copernicus.eu/dhus/#/home.

https://search.asf.alaska.edu/#/

Divya Sekhar Vaka

Please see ASF Vertex (https://vertex.daac.asf.alaska.edu/) for SAR data from different missions such as ERS, ALOS, Radarsat, and Sentinel-1.

Sentinel-1 data can also be downloaded from the Copernicus website.

ERS, ENVISAT data can be downloaded from the ESA OTF service (https://spacedata.copernicus.eu/web/cscda/data-access/access-to-esa-eo-data). You have to write a short proposal for accessing the data. Raw SAR data can also be requested from this service.

ALOS-2, Cosmoskymed, TerraSAR-X SAR data .. are also available. But these datasets are not free.

Jalil Piri

You can download Sentinel-1 data from these websites:

https://scihub.copernicus.eu/dhus/#/home

Gregoriy Kaplan

You can download the Sentinel-1 SLC data from the Copernicus site, but after that, you will have to produce the interferograms by yourself.

Saheed Adekunle Raji

Thank you Dr Abdelmajid Benbouziane are these data sources free.

Does the data from the source you have provided open-source or commercial?

Thank you Dr. Gregoriy Kaplan for your response.

Please can you suggest materials to produce the interferograms as you suggested. Thank you.

@Adekunle S. Raji you're welcome. Yes the data provided by the websites mentioned are free of charge.

Dear Adekunle S. Raji, you are welcome.

Please have a look on this

https://www.researchgate.net/post/SENTINEL-1_IW_Level-1_SLC_vs_GRD

I would recommend you to also read SNAP forum and Sentinel-1 manuals from the Copernicus site. The most important ones are TM-19 manuals, in my opinion.

From Alaska Satellite Facility you can download SAR SLC product.

You can also download SAR data from Copernicus hub

Hristo Nikolov

There is also possibility to download ALOS data from https://gportal.jaxa.jp/gpr/search?tab=1

Enjoy!

Preet Lal Shubham Kumar and Hristo Nikolov

You are all appreciated for your very useful comments and references.

Thank you.
