2 issues:
for the PH datasets, code to remove the attrbs is needed on colab only:

ds_pH = xr.open_dataset(pooch_load(url_SurfacepH,filename_SurfacepH))
ds_pH.attrs=''
ds_pH

updating the new (old) dataset. the FTP provided is temporary :
filename_CO2_CAMS= 'SSTyCO2_CAMS_Copernicus_data.nc'
url_CO2_CAMS='ftp://livftp.noc.ac.uk/noc/gmayapub/data/CMA/SSTyCO2_CAMS_Copernicus_data.nc'
ds_CO2_CAMS =xr.open_dataset(pooch_load(url_CO2_CAMS,filename_CO2_CAMS))
ds_CO2_CAMS

for the pH datasets, the lot and lan index are wrong. need to use the variables stored inside the dataset:
"Hmm..seems like the actual coordinates were stored in the longitude and latitude variables and the coordinates were just dummy values going from 0 to number of coordinates.
