IPCC_ECHAM4OPYC_SRES_A2_MM
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 model consists of the atmospheric component which based
on the weather forecast model of ECMWF. The atmosphere 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
additionel meteorological parameters.
The run produces monthly averaged values of the variabeles.
Changes of anthropogenic emissions 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.

- 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

lwe_large_scale_precipitation_rate "lwe" means liquid water equivalent. [CF-Standard Name]; unit: mm d-1
- Attribute description
- dew_point_temperature-at2m
- Descriptor
-
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
- 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
- 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
- Attribute description
- convective_precipitation_rate
- Descriptor
-
"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
- 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
- surface_snow_melt_flux
- Descriptor
-
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
- Attribute description
- wind_speed-at10m
- Descriptor
-
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
