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 model developed by the Center for Climate System Resaerch/ National Institute for Enviromental Studies in Tokyo consists of the atmospheric component which has vertical resolution of 20 levels and the triangular truncation at wavenumber 21 (T21). The ocean model has 17 vertical levels and the same resolution. ) The changes of anthropogenic emissions of CO2, CH4, N2O and sulphur dioxide are prescribed according to the above mentioned scenario.

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 x_wind "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 specific_humidity "specific" means per unit mass. Specific humidity is the mass fraction of water vapor in (moist) air.[CF-Standard Name]; unit: kg kg-1 air_temperature-atNearSurface Air temperature is the bulk temperature of the air, not the surface (skin) temperature. [CF-Standard Name-vertical_coordinate]; unit: K geopotential_height 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 lwe_convective_precipitation_rate "lwe" means liquid water equivalent. [CF-Standard Name]; unit: mm d-1 air_pressure_at_sea_level 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 surface_temperature 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 air_temperature-atNearSurface (maximum) Air temperature is the bulk temperature of the air, not the surface (skin) temperature. (maximum) [CF-Standard Name-vertical_coordinate-cell_method]; unit: K wind_speed-at10m Speed is the magnitude of velocity. 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.) The wind speed is the magnitude of the wind velocity. [CF-Standard Name-vertical_coordinate]; unit: m s-1 air_temperature Air temperature is the bulk temperature of the air, not the surface (skin) temperature. [CF-Standard Name]; unit: K surface_downwelling_shortwave_flux_in_air surface_downwelling_shortwave_flux_in_air [CF-Standard Name]; unit: W m-2 convective_precipitation_rate "Precipitation rate" means the depth or thickness of the layer formed by precipitation per unit time. Convective precipitation is that produced by the convection schemes in an atmosphere model. "Precipitation" in the earth's atmosphere means precipitation of water in all phases. [CF-Standard Name]; unit: mm d-1 air_temperature-atNearSurface (minimum) Air temperature is the bulk temperature of the air, not the surface (skin) temperature. (minimum) [CF-Standard Name-vertical_coordinate-cell_method]; unit: K soil_moisture_content "moisture" means water in all phases contained in soil. "Content" indicates a quantity per unit area. The "soil content" of a quantity refers to the vertical integral from the surface down to the bottom of the soil model. For the content between specified levels in the soil, standard names including content_of_soil_layer are used.
