Query about GEDI time quantum

Is there exists GEDI campaign table(equivalent to ICESAT-1 which about 91 days for one campaign) so that I could know how to choose time quantum so that it could covered global forest/terrain .If not ,any time quantum for suggestions. Thanks so much for any
information!

@deace ,

It is not clear to me what you’re asking for exactly. GEDI continuously collects lidar samples globally from the International Space Station. If you’re trying to find and access data that spatially and temporally intersect with you research parameters, I would recommend using Earthdata Search (https://search.earthdata.nasa.gov/search) to do this. From there, you can specify an area of interest, a temporal range, and the specific GEDI data product you wish to query against. If this is not what you are looking for, please supply us with some more details regarding what you are accomplish. I’m not familiar with the ICESAT-1 campaign table. Would you be able to provide a link to that resource?

@deace,

Would you be able to share a link to the ICESAT-1 campaign table? I'm curious what it looks like. I don't think there is a 'table' containing the revisit intervals. Is there any reason why Earthdata Search doesn't at least get you partially there? You can search for you area of interest using the Earthdata Search interface to generate a list of scenes through time that you can download. You could then use the python scripts here: https://git.earthdata.nasa.gov/projects/LPDUR/repos/gedi-v2-tutorials/browse to identify the shots you are interested in and process them.
