Accessing the number of times and dates that ISS passed a site

by ckhamila » Thu Mar 23, 2023 9:32 am America/New_York

Is there a way I can get to know the number of times and on which dates the ISS passed a certain study site within coverage year say 2 years. I am working with gedi data and I need to group them based on the time they were scanned/ produced for a time series analysis. Is there an API or any resources that can help me on this?

Also, after processing data following gedi tutorial I noticed there is elev_lowestmode but elev_highestreturn is missing, I am a little bit confused which ones will I use to determine rh

I will really appreciate a quick feedback. Thank you.

Hello,
This can be done using the Earthdata Search Tool: https://search.earthdata.nasa.gov/search
You can enter your Gedi data set and select a date range, it will return all collected granules that fit your search parameters. You may also want to take a look at this: https://openaltimetry.org/data/gedi/
Please let us know if you have any questions.
Thanks,
Brett
