Re: GEDI L1A data access

Hello,
I’m hoping to access Level 1A data (as distinct from Version 1 data) which the ATBD says can be requested.
Thank you.

Re: GEDI L1A data access

Hello,
Thanks for your reply.
Are you sure those options provide access to L1A data? I do not see L1A on EarthdataSearch, for example.
Thank you.

Re: GEDI 'system response impulse' or 'return impulse response'

Hello, Thank you for that. I assume the person from GEDI is referring to the txwaveform layer/field which is easy enough to extract. I am no expert on this, as you probably already tell, but my understanding is that deconvolution also requires a kind of "blank response" or control sample s...

GEDI 'system response impulse' or 'return impulse response'

Hello,
Is there any info available regarding the 'system response impulse' / 'return impulse response' for the GEDI instrument? For context, this would assist with deconvolution of the GEDI waveform.
Thanks in advance.
