Need Help In Programming For CALIPSO Data

by EarthdataForumContributor » Thu Jul 02, 2020 12:14 pm America/New_York

I have downloaded one data file of LID_L2_05kmCLay-Standard-V4-20 from
asdc.larc.nasa.gov/data/CALIPSO [ as am focussing only on cloud layer from 2018 december to 2019 december where out of 12 month, say for 01 month which has 30 or 31 days, i need to collect day and night of each days so total 60 or 62 files, like that for 12 month inorder to observe monthly and seasonal changes]. I have seen other examples in the site (http://hdfeos.org/zoo/index_openLaRC_Ex ... hp#CALIPSO).
I have tried to do programming in matlab with 1 datafile but am not getting results. If i get result from 1 dataset only then i could do data retrieval from below mentioned parameters. Please, help me with coding in MATLAB for my project so that i could figure
out what's my mistake.

Based on your stated goal to identify cloud layers, we would actually recommend to use the cloud classification from the Level 2 Vertical Feature Mask data product CAL_LID_L2_VFM-Standard-V4-20 The HDF ZOO scripts are already written to work with the VFM data.

The VFM will provide you both with cloud classes and type. In the users guide is a summary of the pixel classification, which can also be found on the table here
