GEDI L1B

by meiyuanchen » Thu Mar 16, 2023 10:36 pm America/New_York

hello!I am processing the GEDI L1B Geolocated Waveform Data (https://lpdaac.usgs.gov/products/gedi01_bv002/). This product provides geolocated corrected and smoothed waveforms.Does this mean that the 1B data has already been smoothed and I don't need to smooth it again when processing the waveform and can just denoise it for subsequent processing such as Gaussian decomposition?

Thanks
Maye

Hi Maye,
Sorry for the delay, we passed your questions to the GEDI developers for their suggestions, please see the following:
See the L2A ATBD. Only minor smoothing (2 ns Gaussian width) has been applied to reduce high frequency noise and eliminate ADC artifacts. The user may wish to apply additional smoothing (as is done in L2A processing) but that depends on the details of what they are trying to do.
Let us know if we can be of further assistance.
Thanks,
LPDAAC Team.
