The SRES data sets were published by the IPCC in 2000 and classified

into four different scenario families (A1, A2, B1, B2).

SRES_A1 storyline describes a future world of very rapid economic

growth, global population that peaks in mid-century and declines

thereafter and the rapid introduction of new and more efficient

technologies.

It is distinguished by their technological emphasis:

A1FI: fossil intensiv,

A1T : non-fossil energy sources and

A1B : a balance across all sources.

The Mark 2 CSIRO coupled global climate model consists of the

atmospheric component which has 9 vertical levels with a R21

horizontal resolution and the ocean component which was based

on the GFDL code.

The changes of anthropogenic emissions of CO2, CH4, N2O and

sulphur dioxide are prescribed according to the above

mentioned scenario.
