Hello. Looking for help retrieving range and flag data for the PACE-OCI passes in 2024. When using the following curl:

curl -d "sensor=OCI&start_date=2024-03-01&stop_date=2024-12-31&lat=42.4&lon=-70.8&km_above_sea=0&illuminated=on" https://oceandata.sci.gsfc.nasa.gov/overpass_pred/search/

Sample of output:
{"nonextracted_product_lists":"more stuff","passes":[{"date":" 1 Mar 2024","flags":{"elevation":"","glint":1,"illuminated":1,"old_tle":""},"pass_time":1709312453,"sat":{"az":" 28.40","el":" 60.76","range":" 772"},"sensor_name":"PACE-OCI","sun":{"az":"181.79","el":" 40.39"},"target":{"lat":" 0.000","lon":" 0.000"},"time":"17:00:53"},{"date":" 2 Mar 2024","flags":{"elevation":"","glint":"","illuminated":1,"old_tle":""},"pass_time":1709400978.5,"sat":{"az":"285.11","el":" 48.30","range":" 883"},"sensor_name":"PACE-OCI","sun":{"az":"193.36","el":" 39.91"},"target":{"lat":" 0.000","lon":" 0.000"},"time":"17:36:18"}...

I'm not getting the expected results. The lat and long returned are zeros. I'm more familiar with the overpass flags. Any documentation of these flags (elevation, glint, illuminated, old_tle)? Any idea how to format this into a table?

Thank you!

Hello, we've been thinking about your question. The overpass predictor has been designed with future-looking capabilities in mind. We would have to consider modifying the code and resources to store past information to perform actions that you described. Given current priorities, I do not have a good timeline for outlook of performing this work, but I will mark this post for follow-up in case we are able to work on this soon.

This isn't exactly a solution to the question, but prior orbit tracks are visualized on Worldview (see: https://go.nasa.gov/3F9NxaF)

thank you for the response. Is there another tool or data source I could use to find out what the range, tilt, viewing angle, or sunglint conditions were for the dates where data was collected?
