Hi Katie,

Are you talking about ESMF regridding? And if so, are you using the "conserve" method?

I don't know if there are any best practices, as it probably depends on the spacing of your grid, and the physics behind the points you are regridding.

I'm hoping the ESMF folks have some good suggestions. I've CC'ed them.

If a choose the grid corners to be rounded to zero decimal places, I get a slightly different answer in my final emissions than if I round the grid corner to 2 decimal places which is actually slightly (1%) less than the original emissions. Why would this occur, and what is 'best practices' in choosing the grid corners for this scenario?
