Description

Provide a clear and concise description of what the problem is.
The MERRA2 aerosol data are read for 12 months and save in the memory, which use tremendous memory and some tie

Solution

Add a clear and concise description of what you want to happen.
Because the interpolation in time is linear, two months of aerosol data is needed and a way is found to solve the problem

Alternatives

If applicable, add a description of any alternative solutions or features you've considered.
