Thank you for making the NISAR Provisional products publicly available.
I was pleased to find that data for my local area are already available. My first step will be to evaluate the GUNW products using observations from my region.
I appreciate all the hard work of the NISAR and ASF teams.

Thank you for your reply.

I am looking forward to accessing the calibrated NISAR products next month.

One quick question: will the calibrated data acquired from July 2026 onward be released globally for all observed land areas, or only for certain regions?

Thank you.

When are the calibrated NISAR data products expected to become publicly available? I am planning to submit a presentation on the start of NISAR services to the Autumn Conference of the Japanese Society of Remote Sensing. The abstract submission deadline is at the end of September, so it would be ver...

Thank you for the information.
For now, I tried a different scene, and the one observed yesterday was processed successfully without any issues.

When I attempted to generate pairs in SBAS processing, I encountered an error message as shown in the attached screenshot( 2026/04/28 data error happen) For reference, in the previous scene of the same dataset(2026/04/16 data), pair generation succeeds, but the baseline is shown as 0 m. It seems tha...

**Additional information** This pair worked successfully: * Reference Granule: S1C_IW_SLC__1SDV_20260404T082550_20260404T082617_007064_00E4D3_7FDB * Secondary Granule: S1C_IW_SLC__1SDV_20260416T082551_20260416T082618_007239_00EAB9_8F47 However, when I used the secondary from the above pair as the re...

This morning, when I ran INSAR_GAMMA SLC on HyP3, it failed. I also tried changing the looks from 10×2 to 20×4, but it still resulted in an error. Is there possibly an issue occurring on HyP3?

Thank you for the information. ALOS-2 ScanSAR data are indeed very useful, but currently the openly available dataset appears to extend only until around March 2025. Data acquired after that time are not yet publicly available. In addition, since ALOS-4 began operations in the latter half of last ye...

In many Southeast Asian countries, purchasing ALOS data for SBAS analysis is often economically difficult. In this context, open L-band data from NISAR would be extremely valuable. In addition, preparing high-performance computers for InSAR processing is often not feasible in these regions. Therefor...

Thank you for your explanation. It is not strictly necessary for all interferograms to be provided as GUNW products. If providing custom GUNW pairings on demand is difficult due to resource limitations, it would be very helpful if NISAR data could at least be supported in the existing HyP3 service. ...
