Time Series

From pre-industrial to the next century, the evolution of ocean acification
variables on a regional scale can be viewed in this plot,
displaying the CMIP5 mean as well as the maxima and minima.
Select the variable and oceanic region from the menu below:

Oceanic Regions

The CMIP5 model output is split into oceanic latitudinal areas known as the Mikaloff-Fletcher regions.

The mean, maxima, minima and standard deviation are calculated based on an ensemble of
CMIP5 models in this time series. For the historical period the models used are
CESM1-BGC, CNRM-ESM1, GFDL-ESM2G, GFDL-ESM2M, HadGEM2-ES, IPSL-CM5A-LR,
IPSL-CM5A-MR, MPI-ESM-LR and MPI-ESM-MR in those years where data is available
for all the models, i.e., from year 1860 to year 2100.

The boundary where the Historical period ends is usually defined at year 2005,
and it starts at the end of the Industrial Revolution, circa 1850.

Future scenarios are calculated using the following CMIP5 models:
CNRM-ESM1, GFDL-ESM2G, GFDL-ESM2M, HadGEM2-ES, IPSL-CM5A-LR,
IPSL-CM5A-MR, MPI-ESM-LR and MPI-ESM-MR for RCP 2.6, plus CESM1-BGC for the RCP 8.5.

The curves in this time series have been smoothed using a curveBasisOpen
interpolation for clarity purposes. This interpolation between data points
is based on the native D3.js built-in interpolation techniques.
