Description A numerical experiment was conducted during the harvesting period of potato crop by Lhcmme to estimate sensibleheat flux from radiometric surface temperature over the canopy. The model of Lhomme was in terms of the characteristicsof the crop and meteorological profiles within the canopy. In the model, Lhomme introduced an additional resistance socalled canopy aerodynamic resistance. Hence the total resistance to the heat transfer from canopy to the air is the sum ofcanopy aerodynamic resistance and usual classical aerodynami.c resistance. It is not very easy to work out analyticalsolutions for the additional aerodynamic resistance. In this paper, an attempt is made to reformulate the model andpresent the simplified mathematical procedures to calculate the canopy aerodynamical resistance. Finally, the predidictionsof the reformulated model were compared with those of Lhomme's model.
