Hello, We apologize for the delay but the fall 2021 final products are starting the processing this week and hope to have it all done by the end of next week and should be available by early April. Dec 2021 is part of the WINTER season so it will be processed later – probably late April. In the mean...

Hello, Just from looking at your code, you might have a typo. You say that the MODIS file works using the same code but for CALIPSO, it says that r1 = session.get(url) and for MODIS it says r1 = session.request('get', url). We have also notified a subject matter expert on your inquiry. Thank you. Re...

Hello, Here is a sample of how to simply open CALIPSO file in HDF using MATLAB: %Tested with MATLAB R2021a import matlab.io.hdf4.* % Open the HDF4 File. FILE_NAME = 'CAL_LID_L2_VFM-ValStage1-V3-41.2021-11-29T23-32-39ZD.hdf'; SD_id = sd.start(FILE_NAME, 'rdonly'); If you would like to read and plot C...

Hello,

They would recommend you use the transmit pulse (tx waveform) as the impulse response for deconvolution. If noise is an issue, then you could average several TX waveforms together or lowpass filter them to get a cleaner version.

Thanks

Hello, We have contacted someone from GEDI and they have stated that: The transmit pulse for each laser shot is the “impulse response” of GEDI for that channel/shot and is contained in the L1B data record. The transmit pulse is the system response to the transmitted laser pulse and is the narrowest ...
