The SRES data sets were published by the IPCC in 2000 and classified
into four different scenario families (A1, A2, B1, B2).
SRES_A2 storyline describes a very heterogeneous world
with the underlying theme of self-reliance and preservation
of local identities. It results in this scenario a continous
increasing population together with a slower economic growth
and technological change.
The atmospheric component solves the primitive equations using
a spectral transform method, GFDL_R30 means a rhomboidal 30
truncation and the ocean component solves the primitive equation
of motion using the Boussinesq, rigid-lid and hydrostatic
approximation and based on GFDL Modular Ocean Model version 1.
The changes of anthropogenic emissions of CO2, CH4, N2O and
sulphur dioxide are prescribed according to the above
