Data gap from July 28

by andyrpon_3vg » Thu Aug 06, 2026 2:56 pm America/New_York

I was searching for NISAR data and noticed that there are no NISAR data products available on ASF Vertex from July 28, 2026 onwards as of August 6th. Given the expected latency of up to 72 hours, I would have expected multiple days of data to be available between July 28 and August 6. I was also under the impression that the current plan was to process and release all data as it comes in at this point. Can I ask for any information about why the data release has been paused and if there is an estimated time on when it may resume?

I am also waiting for the release of the data after July 28. A relatively large earthquake occurred in Kumamoto, Japan, on July 28, and I believe the corresponding NISAR data would provide a valuable opportunity to demonstrate the capabilities of NISAR for measuring earthquake-related surface deformation. I hope the data release will resume soon.

NISAR data products are being received from JPL since yesterday, August 10, including urgent response products.

Thank you for your patience!

The data over large areas in Northern Europe are still missing since end of July. The image attached shows available (blue grid) unavailable areas (no grid) in August.

I suspect that what is causing these gaps is not missing data, but the way Vertex displays search results on the map. There is an option to adjust the number of results displayed by using the down arrow under the SEARCH button. Up to 2,000 results can be displayed. If your setting is fewer than the number of files found in the search, not all results will be displayed. Adjusting the setting to a higher number should fill in the gaps.
