IPCC-DDC_CCCma_CGCM2_SRES_A2: 201 YEARS MONTHLY MEANS Canadian Centre for Climate Modelling and Analysis Canada

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 AGCM2 is a spectral model with

triangular truncation at wave no. 32 and 10 vertical levels.

The ocean model component based on the GFDL MOM 1.1 code

with 29 vertical levels and has a isopycnal / eddy stirring

parameterization (Gent and McWilliams, 1990).

CGCM2 ( http://ec.gc.ca/ccmac-cccma/default.asp?lang=En&n=40D6024E- 1 ).

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

sulphur dioxide are prescribed according to the above

mentioned scenario.

These data belongs to a set of three ensemble runs, with the

CCCma-model, using the SRES_A2 scenario. They provide monthly

averaged values of selected variables for the IPCC-DDC.

Name of measure: n/a

Measure description: None

Attribute description: air_temperature-atNearSurface

Descriptor: Air temperature is the bulk temperature of the air, not the surface (skin) temperature. [CF-Standard Name-vertical_coordinate]; unit: K

Attribute description: surface_temperature

Descriptor: The surface called "surface" means the lower boundary of the atmosphere. The surface temperature is the (skin) temperature at the interface, not the bulk temperature of the medium above or below. [CF-Standard Name]; unit: K

Attribute description: x_wind (variance)

Descriptor: x_wind-variance [CF-Standard Name (cell_method)]; unit: m2 s-2

Attribute description: air_temperature-atNearSurface (minimum)

Descriptor: Air temperature is the bulk temperature of the air, not the surface (skin) temperature. (minimum) [CF-Standard Name-vertical_coordinate-cell_method]; unit: K

Attribute description: specific_humidity

Descriptor: "specific" means per unit mass. Specific humidity is the mass fraction of water vapor in (moist) air.[CF-Standard Name]; unit: kg kg-1

Attribute description: y_wind

Descriptor: "y" indicates a vector component along the grid y-axis, when this is not true latitude, positive with increasing y. Wind is defined as a two-dimensional (horizontal) air velocity vector, with no vertical component. (Vertical motion in the atmosphere has the standard name upward_air_velocity.)[CF-Standard Name]; unit: m s-1

Attribute description: wind_speed-atNearSurface

Descriptor: wind_speed-atNearSurface [CF-Standard Name-vertical_coordinate]; unit: m s-1

Attribute description: air_pressure_at_sea_level

Descriptor: sea_level means mean sea level, which is close to the geoid in sea areas. Air pressure at sea level is the quantity often abbreviated as MSLP or PMSL.[CF-Standard Name]; unit: Pa

Attribute description: surface_downwelling_shortwave_flux_in_air

Descriptor: surface_downwelling_shortwave_flux_in_air [CF-Standard Name]; unit: W m-2

Attribute description: x_wind

Descriptor: "x" indicates a vector component along the grid x-axis, when this is not true longitude, positive with increasing x. Wind is defined as a two-dimensional (horizontal) air velocity vector, with no vertical component. (Vertical motion in the atmosphere has the standard name upward_air_velocity.)[CF-Standard Name]; unit: m s-1

Attribute description: sea_ice_thickness

Descriptor: sea_ice_thickness [CF-Standard Name]; unit: kg m-2

Attribute description: geopotential_height (variance)

Descriptor: Geopotential is the sum of the specific gravitational potential energy relative to the geoid and the specific centripetal potential energy. Geopotential height is the geopotential divided by the standard acceleration due to gravity. It is numerically similar to the altitude (or geometric height) and not to the quantity with standard name height, which is relative to the surface. The Cell Method is variance. [CF-Standard Name (cell_method)]; unit: gpm2

Attribute description: geopotential_height

Descriptor: Geopotential is the sum of the specific gravitational potential energy relative to the geoid and the specific centripetal potential energy. Geopotential height is the geopotential divided by the standard acceleration due to gravity. It is numerically similar to the altitude (or geometric height) and not to the quantity with standard name height, which is relative to the surface. [CF-Standard Name]; unit: gpm

Attribute description: lwe_convective_precipitation_rate

Descriptor: "lwe" means liquid water equivalent. [CF-Standard Name]; unit: mm d-1

Attribute description: snowfall_amount

Descriptor: snowfall_amount [CF-Standard Name]; unit: kg m-2

Attribute description: surface_temperature (variance)

Descriptor: surface_temperature (variance) [CF-Standard Name (cell_method)]; unit: degC2

Attribute description: air_temperature-atNearSurface (maximum)

Descriptor: Air temperature is the bulk temperature of the air, not the surface (skin) temperature. (maximum) [CF-Standard Name-vertical_coordinate-cell_method]; unit: K
