Extracting data by lat/lon

[acrunyon]

Hello, I work for the National Park Service and would like to use this data for some of our analysis but need to extract the data by lat/lon. Best I can tell the .nc files have index value for the lat/lon fields but the PaleoView tool allows a custom extraction by coordinates so is there an underlying grid that defines the coordinates each cell?

This is a very cool tool and nice to be able to put more recent and projected future climate in context of paleoclimate record for some of the parks that emphasize their archaeological histories.
