* Time-series can be averaged across 0E using negative longitudes for 1st longitude bound. Actual grid center of the bounds used in each dataset are returned below the plot. Grid resolutions differ so datasets will potentially use slightly different lat/lons for the same input lat/lon.NCL uses the closest grid.
