<br>
I am trying to read CALIPSO L2 profile data. According to the Application examples, NCL doesn’t not read HDF data therefore, we need to use hep dumped to get the liar altitude. However, when I tried and got "hdp: Command not found.” (I installed HDF5 because it didn’t work before so I looked for hdf which I didn’t have).<br>
<br>
Could you please help me how I can get data from CALIPSO?<br>
I appreciate any comments and helps.<br>
<br>
Best,<br>
