HadCM3 model output prepared for CMIP5 decadal experiments, served by ESGF

decadals are a group of experiments of the CMIP5 - Coupled Model Intercomparison Project Phase 5 ( https://pcmdi.llnl.gov/mips/cmip 5 ). CMIP5 is meant to provide a framework for coordinated climate change experiments for the next five years and thus includes simulations for assessment in the AR5 as well as others that extend beyond the AR5.

1.5 decadal (1.5 decadal hindcast/forecast utilizing alternative initializations.) - Version 1: Decadal hindcast/prediction. Comparison of initialization strategies - for example, a repeat of experiment 1.1 using an alternate initialization strategy or alternate initial data. Individual decadal experiments are named decadalXXXX with starting year XXXX.

The surface called "surface" means the lower boundary of the atmosphere. "Eastward" indicates a vector component which is positive when directed eastward (negative westward). "Downward" indicates a vector component which is positive when directed downward (negative upward). "Downward eastward" indicates the ZX component of a tensor. A downward eastward stress is a downward flux of eastward momentum, which accelerates the lower medium eastward and the upper medium westward. The surface downward stress is the windstress on the surface. [CF-Standard Name]; unit: Pa

Attribute description
northward_wind
Descriptor

"Northward" indicates a vector component which is positive when directed northward (negative southward). 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
soil_temperature
Descriptor

Soil temperature is the bulk temperature of the soil, not the surface (skin) temperature. [CF-Standard Name]; unit: K

Attribute description
sea_surface_temperature
Descriptor

Sea surface temperature is usually abbreviated as "SST". It is the temperature of sea water near the surface (including the part under sea-ice, if any), and not the skin temperature, whose standard name is surface_temperature. For the temperature of sea water at a particular depth or layer, a data variable of sea_water_temperature with a vertical coordinate axis should be used. [CF-Standard Name]; unit: K

surface_air_pressure
Descriptor

The surface called "surface" means the lower boundary of the atmosphere.[CF-Standard Name]; unit: Pa

surface_downward_heat_flux_in_snow
Descriptor

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

Attribute description
toa_outgoing_longwave_flux_assuming_clear_sky
Descriptor

A phrase assuming_condition indicates that the named quantity is the value which would obtain if all aspects of the system were unaltered except for the assumption of the circumstances specified by the condition. "longwave" means longwave radiation. "toa" means top of atmosphere. The TOA outgoing longwave flux is the upwelling thermal radiative flux, often called the "outgoing longwave radiation" or "OLR". In accordance with common usage in geophysical disciplines, "flux" implies per unit area, called "flux density" in physics. [CF-Standard Name]; unit: W m-2
