Sample dataset from Kalpana satellite is attached. Need to extract the insolation values for a particular latitude and longitude.
Dear Karthikeyan Elango ,
Maybe, It helps.

Karthikeyan Elango, give this a go.
HDF5 files can be read in Python using the netCDF4 package's Dataset object. For this particular file, the latitude data appears to be stored in the path "INS/Latitude"; similarly, the longitude data is stored in "INS/Longitude". I have written a small script (see the attachment) to demonstrate how to access the data and store it as a numpy.ndarray object. Let me know if you have any questions.
Dear Erick Edward Shepherd , Thanks for your kind reply and the efforts you have taken. I used your code to read the latitude, longitude and insolation values from the hdf file. Please refer the attached image.
My purpose is to find the insolation for a particular latitude and longitude.
Say for example latitude = 45.5, longitude = 105.3751, Insolation=??? . How do I do that?
I am looking for something similar to the one shown in below link, but that example code in below link doesn't seem to work for me. https://www.researchgate.net/deref/https%3A%2F%2Fgis.stackexchange.com%2Fquestions%2F261061%2Fextract-value-for-a-given-coordinate-from-hdf5-file
Dear Thieu Nguyen , Thank you very much for your reply and the links. I tried to modify the code in the example for my application, but I couldn't figure out what could be the problem. Refer attached image showing my output. I wanted to display the insolation data for that particular latitude and longitude but my output shows null value.
