Update 1

We have recently discovered that there is an error in the GLODAPv2 grid which means that the mapped climatologies do not align correctly with the topography. We will fix it and update the files here at CDIAC as soon as possible. In the meantime, use the following procedure to align the mapped climatologies with land:

1) Add 1degree to the variable called lon so that lon_corr=lon+1
2) Plot the fields with the lat,lon_corr coordinates in the middle of the cell

Because of this error in the grid the GLODAPv2 mapped climatologies do not align with GLODAPv1 or with WOA (they are shifted half a degree). Because of the correction to align with topography GLODAP2 is also a missing cell at the North Pole. We apologize for the confusion and inconvenience and will fix this as soon as possible.
