 The saturated vapour pressure can be calculated using a number of equations. A commonly used equation is that proposed by WMO in the Guide to Meteorological Instruments and Methods of Observation (CIMO Guide by WMO, 2008) [(Guide to Meteorological Instruments and Methods of Observation, WMO Publication No 8, 7th edition, Geneva, 2008.  )]
-| $$  e_s = 0.61120*exp \left (\frac {17.62*T}{243.12+T} \right )   $$  |   |

 where the temperature is given in degress Celsius and the resulting vapour pressure is in kPa. This type of equation can be found in different varieties, with slightly different coefficients (see e.g. [(Buck Research Manual (1996); updated equation from Buck, A. L., New equations for computing vapor pressure and enhancement factor, J. Appl. Meteorol., 20, 1527-1532, 1981)] )
