Data gap from July 28

[andyrpon_3vg]

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.



Please let me know if this doesn't help.

Thank you for a quick answer.
The problem was not the display limit, as visible form the Northern Europe overview image produced with the same search parameters as the original image. Images appeared in ASF yesterday.
Though, the the coverage is partial in time, as seen in an Example over Estonia, where 4 Aug image is missing in both desc and asc orbits.

The NISAR satellite experienced an anomaly from July 28 to August 9, during which no acquisitions were made and, therefore, no data products are available.

GUNWs are missing over Northern Europe since the provisional data release (since June to date; while only RSLC, GSLC and GCOV are present). What is the reason for this anomaly and will GUNW be released soon? Thanks.

It appears that by applying the "Range Bandwidth" filter, you are limiting the results available for GUNW products over this area. If you remove the filter, approximately 92 GUNW files are available at a 20 MHz bandwidth.
