Quesition about CALIPSO height and CAD_score

by 2201110307 » Mon Nov 06, 2023 2:30 am America/New_York


I want to use CALIPSO L2 VFM and APro data, but some questions confuse me.

(1) The height of VFM data is 545 layers, but the height of Apro data (for example Extinction_Coefficient_1064 ) is 399 layers. What is the corresponding relationship between their heights?
(2) The data shape of CAD_scores (in Apro data) is (N, 399, 2), N is the number of observations, 399 is height, what is 2?

Look forward to your reply, thank you!!!

hi 2201110307,

To answer your first question, please compare the "Profile Spacial Resolution" tables on the top of page 42 (Apro) and page 53 (VFM) in the following document.


To answer your second question, please see the following reference page.


Thank you,
