This catalogue entry provides daily climate projections on single levels from a large number of experiments, models, members and time periods computed in the framework of the fifth phase of the Coupled Model Intercomparison Project (CMIP5). The term "single levels" is used to express that the variables are computed at one vertical level which can be surface (or a level close to the surface) or a dedicated pressure level in the atmosphere. Multiple vertical levels are excluded from this catalogue entry.

| MAIN VARIABLES | ||
|---|---|---|
| Name | Units | Description |
| 10m wind speed | m s-1 | Magnitude of the two-dimensional horizontal air velocity near the surface. |
| 2m temperature | K | Temperature of the air near the surface. |
| Maximum 2m temperature in the last 24 hours | K | Daily maximum near-surface air temperature. |
| Minimum 2m temperature in the last 24 hours | K | Daily minimum near-surface air temperature. |
| Mean precipitation flux | kg m-2s-1 | Amount of water per unit area and time. |
| Mean sea level pressure | Pa | Time average of the air pressure at sea level. |
| Near-surface specific humidity | 1 | Amount of moisture in the air near the surface divided by amount of air plus moist at that location. |
| Near-surface relative humidity | % | Usually 2m relative humidity. This is the relative humidity with respect to liquid water for T> 0 C, and with respect to ice for T<0 C |
| Snowfall | kg m-2s-1 | Mass of water in the form of snow precipitating per unit area. |
| Surface solar radiation downwards | W m-2 | Radiative shortwave flux of energy downward at the surface. |
