Was brought to our attention via social media: https://twitter.com/hubgeology/status/1531027534355173376?s=21&t=6sNQiMq_YGmqMJ2g7-EM6g

Here are the ASF products (will be removed shortly): https://search.asf.alaska.edu/#/?zoom=7.922&center=44.238,38.776&dataset=SENTINEL-1%20INTERFEROGRAM%20(BETA)&polygon=POLYGON((44.2476%2039.6958,44.344%2039.6958,44.344%2039.7477,44.2476%2039.7477,44.2476%2039.6958))&start=2015-01-01T08:00:00Z&end=2022-05-31T06:59:59Z&resultsLoaded=true&granule=S1-GUNW-A-R-072-tops-20171018_20170930-150133-00042E_00038N-PP-8b7f-v2_0_5-amplitude

The Glo-30 site has a file called blacklist.txt

To Reproduce
Here is one example of product and reference/secondary scenes:

[{'product_id': 'S1-GUNW-A-R-072-tops-20171018_20170930-150133-00042E_00038N-PP-8b7f-v2_0_5',
  'product_version': 'v2_0_5',
  'reference_scenes': ['S1A_IW_SLC__1SDV_20171018T150120_20171018T150147_018869_01FDFA_449D'],
  'secondary_scenes': ['S1B_IW_SLC__1SDV_20170930T150032_20170930T150059_007623_00D762_F517',
   'S1B_IW_SLC__1SDV_20170930T150057_20170930T150124_007623_00D762_A39F']}]

Expected behavior
To be determined. Likely provide url to glo-90 tiles within tile extents for "filling in" missing data.
