Handling the MERGED and EMMA v3 co2 data?

I have been trying to work on the above data set. The Level 2 data is not in gridded format. So, I converted them into 2 * 2 grid boxes. However, when I am trying to plot the monthly data over the Indian region a major portion of the data is getting cut. Pls, refer to the attachment.

Could anyone tell me what is the issue happening? If needed I can share the code I wrote.

Thanking you in advance.
