a = 7.5;
b = 237.3; %degrees C
es = 6.107*10.^(a.T./(b+T));
s = es
log(10)ab./(b+T).^2;

Suggest to change this to eq. (6), Murray (1967) On the computation of water vapor pressure, J. Appl. Meteorol.,

es0 = 6.1078;

over water:
a = 17.2693882;
b = 35.86;

over ice:
a = 21.8745584;
b = 7.66;

es = es0exp(a.(T-273.16)./(T-b));
[ des/dT = es.((273.16-b)./(T-b).^2 ]
s = es.
((273.16-b)./(T-b).^2 ;

Somebody please double check
