And here are my very first results with these new #NASA #NISAR data.
I had to debug a few my NISAR data reader to correctly read the frequencyB layer.
Now it is working.
Here are both frequency A and B differential interferograms on Ethiopia showing the November 2025 volcanic eruption.

This is not a #NISAR interferogram but....
It is issued from the available #NISAR sample data set made from #ALOS 2 #SAR acquisition of October 12 and November 27, 2008.
This to show to that my #NISAR data reader is now functional making the #AMSTerEngine and #AMSTer toolbox #NISAR ready!

Still playing with newly released #Sentinel1C image.

An Extended Wide swath (EW) image was acquired on south #Groenland by #Sentinel1C on February 6, 2025.

The day before, a classical Interferometric Wide swat (IW) image was acquired by #Sentinel1A.

Both images were acquired in polarisation HH - HV.

I coregister both images like it was an interferometric #InSAR pair and make this short animation showing sea currents variation in this one-day interval.

So, my InSAR soft compliance with #Sentinel1C strip map (SM), Interferometric Wide swath (IW) and Extended Wide swath (EW) acquisition modes is now fully verified.
