Calculation Formula

T = Tref + (Δδ18O / α)

Where:
T = Surface air temperature (°C)
Tref = Reference temperature (°C)
Δδ18O = Change in oxygen isotope ratio (‰)
α = Fractionation factor

Working Principle

The Jackson and Pollock equation is used to estimate the surface air temperature from ice core data based on the oxygen isotope ratio. The oxygen isotope ratio (δ18O) in ice cores can provide information about past temperatures. By using the reference temperature and the change in the oxygen isotope ratio, the surface air temperature can be estimated.
