Re: How to open MISR L3 aerosol product in Python?

Hello vasu_007 , Have you considered level 3 data (averaged global gridded products) instead of level 2? Using level 3 will be a lot easier for you to work with. If you decide to use open_mfdataset, you may consider using the group= and/or the combine='nested' keyword arguments. Also, if you decide ...

Re: How to open MISR L3 aerosol product in Python?

Hello, Thank you for your interest in MISR data. The reason why the dataset seems empty when trying to use xarray is because xarray can only be used if variables are at the root level.
