<div> My questions are :<br>
</div>
<div><br>
</div>
<div> 1. How to read variables under the group in .h5 ? I saw one example in (http://www.ncl.ucar.edu/Applications/Scripts/hdf5_2.ncl) , but it did not work. However, when I did the following : <br>
</div>
<div>b = f->AerosolOpticalDepth_at_550nm<br>
</div>
<div><br>
it shows , </div>
<div>
<div>Variable: b</div>
<div>Type: ushort</div>
<div>Total Size: 76800 bytes</div>
<div> 38400 values</div>
<div>Number of Dimensions: 2</div>
<div>Dimensions and sizes: [DIM_001 | 96] x [DIM_002 | 400]</div>
<div>Coordinates:</div>
<div>Number Of Attributes: 0​<br>
</div>
<div><br>
</div>
<div> Is there any other way, variables under the group can be read ?<br>
</div>
<div><br>
</div>
<div>2. how to attach lat-lon along with the variables here.<br>
</div>
<div><br>
</div>
<div>If you need the original file, I can send it is less than 1 mb.<br>
</div>
<div><br>
</div>
<div> Thanks.<br>
