      abstract     = {Estimation of daily evapotranspiration (ET0) is required
                      for efficientirrigation management in Senegal but physically
                      based equations such as thePenman–Monteith (PM) approach
                      need large inputs data which are not alwaysavailable.
                      Therefore empirical approaches such as Turc’s formula are
                      often used.Unfortunately, This latter showed high annual ET0
                      compared to FAO Penman–Monteith (FAO-PM) ET0 for stations
                      in this region. Moreover, Turcunderestimates mean daily ET0
                      for the dry season and overestimates ET0 forthe wet season.
                      For reevaluation, Turc’s empirical parameters (a and b)
                      werefitted to match FAO-PM ET0, whereby the fitting did not
                      improve the predictionsubstantially and only assuming C
                      being independent on relative humidityyielded better
                      agreement. In a second step universal a and b parameters
                      wereestimated for different stations in Senegal. The results
                      indicate that one set ofparameters (a and b) can be used to
                      predict all station ET0 with fairly highaccuracy indicated
                      by a R2 of 0.80 and an RMSE of 0.71 mm day-1. Based onthese
                      findings we propose to use Turc’s approach in Senegal only
                      with theparameters a = 0.16 and b = 29.19 with the constrain
                      that C is independent onrelative humidity.},
