Hope this helps,

This is a free processed data but is provided for a limited time.

Dear Sadegh,

AWS is not free service. I meant a free to charge portals.

Mundi DIAS has started offering it over limited areas:

"Mundi provides Level 2 SLC with 6-days coherence and Level 2 GRD back-scattering products, which unlock to power of earth observation for agriculture."

Given the amount of processing required to produce S-1 coherence it's at present time unrealistic to think it could be made available for free, in my opinion. Hopefully this situation will improve at some point in time.

The Alaska Satellite Facility (ASF) offers a free SAR processing service - Hybrid Pluggable Processing Pipeline (HyP3). HyP3 provides two types of data:

• Radiometrically Terrain Corrected (RTC) Sentinel-1;
• Interferometric SAR Sentinel-1 (contains interferogram, coherence and displacement map, among others).

The quota is 250 tasks per month per user.

Dear Vahid

Here is a LicSAR link to access ifg and coh stacks over the Sentinel-1A/B spanning period but in 100m res.
