Question about the Sentinel-1 InSAR Data coverage

[CalvinDrStar]

Dear Prof. Morishita,

I am trying to use LiCSBAS to study the subsidence in central and eastern China. However, the corresponding LiCSAR products are not available on the COMET-LiCS web portal (https://comet.nerc.ac.uk/COMET-LiCS-portal/), also as you mentioned in your paper (Remote Sens. 2020, 12, 424) "up-to-date LiCSAR products are available primarily over the Alpine Himalayan Belt, Japan, the East African Rift".

So I would like to ask if there are any other unwrapped interferograms and coherence products like LiCSBAS that we, who are not from remote sensing field, can use directly? if possible, even the products derived based on Sentinal-2 and Sentinal-3?

Thanks for your assistance in the issue.
Respectfully submitted.

I recommend requesting the LiCSAR processing in your frame of interest from the form on the LiCS portal web (https://comet.nerc.ac.uk/comet-lics-portal/, right column). See also #6, #9, #30.

Sorry Prof. Morishita, I have checked the LiCS portal web again and also #6, #9, #30.，but still donot really get it. I mean the data in the area circled by the red dotted line in the figure below.

Thanks again for your help in this issue.

The request form is in the right bottom. If you would like to request the frames that have not been initiated and the frame ID is unknown, just send an email to comet@leeds.ac.uk with the image above attached.

Now I finally understand why I cannot find the "right column"，since without using VPN, for the users in china, the Twitter part and the "right column" part cannot be displayed successfully as shown above.

Sorry for the inconvenience and thank you so much for your help this issue.

Professor Morishita;
I have already sent an email to comet@leeds.ac.uk with an attached image the illustrates my study area location which does not have a defined Frame ID. Since there's no data available for LiCSBAS the request is not guaranteed to be processed because my study area is far away from the Alpine-Himalayan tectonic bell, what other options may I consider in the mean time so that my project continues?
