That may help with some of your questions. What GEDI beams (power vs coverage) you decide to use is dependent on your research re...

Re: Unable to access HLSS30.020 on aws s3

Something to note, when interacting with S3 buckets or trying to access data directly in S3 is that you must be running your code/making requests from AWS region us-west-2.
