                         S{\~a}o Martinho da Serra. First of all, empiric models described 
                         by Collares-Pereira and Rabl (CPR) and by Ruth and Chant (RC) were 
                         employed and their performance was evaluated using mean bias error 
                         and root mean square error. Afterwards, a new empiric model, 
                         designates as SMS, was developed following a similar methodology . 
                         The model SMS showed a better performance when compared to CPR and 
                         RC models. The model SMS presented a RMSE=0,073 and MBE lower than 
                         -0,001. The other two models presented a RMSE between 0,108 and 
                         0,111, and MBE between 0,043 and 0,048.",
