Description:
Data used in Climate Change 1995, the Second Assessment Report (SAR) of the United Nations Intergovernmental Panel on Climate Change (IPCC).
Simulations of global climate models were run by various climate modelling groups coordinated by the World Climate Research Programme (WCRP) on behalf of the United Nations Intergovernmental Panel on Climate Change (IPCC).
Climatology data calculated from global climate model simulations of experiments representative of IPCC Scenarios IS92 a and d.
The climatologies are 30-year averages. Climate anomalies are expressed relative to the period 1961-1990. The monthly climatology data covers the period from 1961-2100. The climatologies are of global scope and are provided on latitude-longitude grids.

Climatology data calculated from global climate model simulations for IS92
experiments a and d. The climatologies are 30-year averages. Climate anomalies
are expressed relative to the period 1961-1990. Models: CCCma/CGCM1: Canadian
Global Coupled Model, CGCM1. A spectral model with triangular truncation at wave
number 32 (roughly 3.7¬?x3.7¬? latitude/longitude) and 10 vertical levels. The
ocean component is based on the GFDL MOM1.1 with a resolution of approximately
1.8¬?x1.8¬? and 29 vertical levels. CCSR/NIES: A coupled ocean-atmosphere model
that consists of the CCSR/NIES atmospheric GCM, the CCSR ocean GCM, a
thermodynamic sea-ice model, and a river routing model. The spatial resolution
is T21 spectral truncation (roughly 5.6¬? latitude/longitude) and 20 vertical
levels for the atmospheric part, and roughly 2.8¬? horizontal grid and 17
vertical levels for the oceanic part. CSIRO-Mk2b: The CSIRO Atmospheric Research
Mark 2b climate model atmosphere has 9 levels in the vertical and horizontal
resolution of spectral R21 (roughly 5.6 by 3.2 degrees). The ocean model has the
same horizontal resolution with 21 levels. ECHAM-4: The ECHAM-4 model is a
spectral transform model with 19 atmospheric layers and the results used here
derive from experiments performed with spatial resolution T42 (roughly 2.8¬?
longitude/latitude). GFDL-R15: The model has interactive clouds and seasonally
varying solar insolation. The atmospheric component has nine finite difference
(sigma) levels in the vertical. This version has a rhomboidal resolution of 15
waves (R15) roughly 4.5¬? latitude by 7.5¬? longitude. The model has global
geography consistent with its computational resolution and seasonal (but not
diurnal) variation of insolation. HadCM2: HadCM2 has a spatial resolution of
2.5¬? x 3.75¬? (latitude by longitude) and the representation produces a grid
box resolution of 96 x 73 grid cells. This produces a surface spatial resolution
of about 417km x 278 km reducing to 295 x 278km at 45 degrees North and South
(comparable to a spectral resolution of T42). NCAR-DoE: The NCAR-DoE global
coupled model (sometimes referred to as the Washington-Meehl coupled model) used
in these experiments has an atmospheric component with rhomboidal 15 (R15)
resolution (roughly 4.5¬? latitude by 7.5¬? longitude) with 9 levels, mass flux
convection and a cloud albedo feedback scheme; a global 1¬? by 1¬? 20-level
ocean; and dynamic and thermodynamic sea ice. Experiments: 1% per annum forcing
greenhouse gases only "GG", 1% per annum forcing greenhouse gasses and sulphates
"GS" - equivalent to scenario IS92a: Population rises to 11.3 billion by 2100
and economic growth averages 2.3 % per annum between 1990 and 2100, with a mix
of conventional and renewable energy sources being used. 0.5% per annum forcing
greenhouse gases only "GG", 0.5% per annum forcing greenhouse gasses and
sulphates "GS" - equivalent to scenario IS92d: Population rises to 7.6 billion
in 2025 then falls to 6.4 billion by 2100 and economic growth averages 2.0% per
annum between 1990 and 2100 with increasing use of renewable energy.
