There's no satellite in space that's capable of directly measuring ocean acidity, but an international team of scientists writing in the journal Environmental Science & Technology described last week how satellite measurements of sea surface temperatures, salinity and plankton activity could be combined and used to estimate pH.

And since we don't have good ocean heat content data, nor any satellite observations, or any measurements of stratospheric temperatures to help distinguish potential errors in the forcing from internal variability, it is inevitable that there will be more uncertainty in the attribution for that period than for more recently.
