In: Journal of the Advances in Agricultural Researches 2013.v.18(3)Summary: A ClimGen weather data generator was tested for observed weather data from each of eleven meteorological stations (Alexandria, Mersa Matrouh, Asswan, Minya, Ismailia, Assuit, Bani Sweif, Fayoum, Kafr Al-Sheikh, Shbin Al-Koum and Al-Wadi Al-Gadid) to estimate reference evapotranspiration (ET0). The results showed low error for means and variances of generated data of potential evapotranspiration (ET0) using FAO Penman- Monteith equation. ClimGen appears to perform well across the range of spatial scales and climatic zones found within Egypt. The results showed that ClimGen is able for producing reasonable estimation. The ClimGen model showed a good performance, indicating that representative long-term weather data of reference evapotranspiration could in general, be generated from historical weather data. This finding has particular relevance for agricultural modeling applications in Egypt such as calculation the crop water requirements.
