Résumé : A network of automatic weather stations (Model-Enerco 295-11) each having six sensors (solar radiation, temperature, humidity, wind, rainfall and leaf wetness) was set up across the island of Reunion in December, 1983. Most stations provide data for rainfed and irrigated sugar cane research projects. The modifications that were made to tropicalise the stations to increase the reliability of the network are described. The data collected have been used to calculate evapotranspiration (ETP according to Penman's formula). Monthly data have shown close correlation between ETP and altitude for the cane growing areas of the island. The dominant influence of radiation on the estimates of ETP has been confirmed and the use of the radiation formula to estimate 10-day mean ETP is proposed. The satisfactory correlation obtained between ETP and solar radiation suggests that irrigation scheduling could be carried out at low altitude using only one climatic parameter (solar radiation). A simple relationship has been suggested for the irrigated area at 'Bras de la Plaine'
