SRES_B2 storyline describes a world in which the emphasis is on local solutions to economic, social and enviromental sustainbility. The global population is increasing at a lower rate than A2. It has a intermediate level of economic development and a less rapid and more diverse technological change than in A1 and B1. The model consists of the atmospheric component which based on the weather forecast model of ECMWF. The atmospheric component is the standard model version of a 19-level hybrid sigma-pressure coordinate system. The ocean component is a model which computes with isopycnal coordinates. ECHAM4/OPYC3(https://www.ipcc-data.org/gcm/models/tar/echam4opyc3.html ). This data set is an enlargement of the IPCC data set and provides additional meteorological parameters. The run produces monthly averaged values of the variabeles. Changes of anthropogenic smissions of CO2, CH4, N2O and sulphur dioxide are prescribed according to the above mentioned scenario. The model run starts in 1990 from the results of the scenario run GSDIO (Experiment "EH4OPYC_22723GSDIO") which has been run with observed conditions for the time period 1860-1990.

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 lwe_large_scale_precipitation_rate lwe_large_scale_precipitation_rate "lwe" means liquid water equivalent. [CF-Standard Name]; unit: mm d-1 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 y_wind "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 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 dew_point_temperature-at2m Dew point temperature is the temperature at which a parcel of air reaches saturation upon being cooled at constant pressure and specific humidity.[CF-Standard Name-vertical_coordinate]; 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 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 surface_snow_melt_flux The surface called "surface" means the lower boundary of the atmosphere. In accordance with common usage in geophysical disciplines, "flux" implies per unit area, called "flux density" in physics. For unit "m day-1" the water equivalent of snow melt is given. [CF-Standard Name]; unit: mm d-1 surface_downwelling_shortwave_flux_in_air surface_downwelling_shortwave_flux_in_air [CF-Standard Name]; unit: W m-2 air_temperature-atNearSurface Air temperature is the bulk temperature of the air, not the surface (skin) temperature. [CF-Standard Name-vertical_coordinate]; unit: K 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 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 lwe_convective_precipitation_rate "lwe" means liquid water equivalent. [CF-Standard Name]; unit: mm d-1 air_temperature Air temperature is the bulk temperature of the air, not the surface (skin) temperature. [CF-Standard Name]; 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 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.
