These are non-exclusive grouping of CMIP variables (e.g. monthly time slices of the baseline variables). Variables can belong to more than one group.

| justification | This group of variables consists of those that are required to both quantify daily temperature variability and to understand the processes involves. This group contains the lower priority variables for this opportunity: - daily surface temperature, which can be useful for understanding the behavior of sensible heat flux when paired with daily surface air temperature. - daily temperature. This is useful for diagnosing mid-tropospheric moist static energy which has been used to develop theories for surface temperature variability and the upper bounds of temperature extremes e.g., Zhang and Boos (2023, 10.1073/pnas.2215278120), Byrne (2021, 10.1038/s41561-021-00828-8) and for diagnosing temperature advection. 500 hPa and 850 hPa would be the most relevant levels. - daily zonal and meridional winds on pressure levels. Useful for diagnosing temperature advection. 850 hPa would be the most relevant levels. - daily hus. This is also useful for diagnosing moist static energy which has been used in theories of temperature variability and extremes. Note that zg is also needed for that but it is specified in the higher priority variable group. - Potential evapotranspiration (evspsblpot) - useful for quantifying aridity. - Relative humidity which is useful for fire weather indices and for quantifying dryness. - Runoff variables mrro and mrros which would be useful for understanding soil moisture evolution given soil moistures important control on temperature extremes - Daily precipitation which is also useful for understanding the evolution of soil moisture. - Daily surface pressure which is useful for calculating vapor pressure deficit. - Daily sea level pressure which is useful for examining the circulation anomalies associated with temperature variability - Clear sky surface longwave and shortwave downward fluxes which can be paired with the higher priority all sky equivalents to examine the impact of clouds on the surface energy balance. - Daily surface wind speed which could be used to understand the behavior of surface and latent heat fluxes (which modulate temperature variability) - Daily minimum and maximum boundary layer height which can be used to diagnose how the boundary layer is behaving within temperature extremes. |
