Common Model Input Data
HadISST 1.1 Data Set
Sea Surface Temperature and Sea Ice Cover Data for the period 1870-2003.
Isotope General Circulation Model Simulations
All model simulation output files have been produced using the
SWINGIO software tool (see README
file contained in this software package for details on file and variable
The different GCM model grids have been interpolated to a common 2x2 degree grid for comparison reason.
- Experimet S1A:
Climatology control run with prescribed SST from HadISST data set, mean of period 1980-1999, other boundary conditions set to 1980's value.
- Experimet S1B:
134-years simulation with varying SST from the HadISST data set, period 1870-2003, other boundary conditions set accordingly.
Observational Isotope Data
Global Network of Isotopes in Precipitation (GNIP)
You may download 2 different GNIP datasets (MS-Excel
(1) Arithmetic and weighted monthly means of oxygen-18, deuterium, deuterium excess, precipitation amount, surface air temperature and water vapour pressure calculated for the period 1961-2001 for stations having at least 3 years of information.
(2) Arithmetic and weighted annual
averages of oxygen-18, deuterium, deuterium excess, surface air
temperature, precipitation amount and water vapour pressure calculated
for individual years of the period 1961-2001.
