Study of Land Surface Radiation and Energy Balance at Winter Wheat Fields over Typical Mesa of Chinese Loess Plateau
黄土高原典型塬区冬小麦地表辐射和能量平衡特征

Based on the observations of Loess Plateau Experiments from April-July in 2007,characteristics of land surface flux of the growing winter wheat in different weather conditions over the typical mesa of Chinese Loess Plateau are analyzed.The results indicate that there is large variation in the energy balance in different weather conditions.The value of the upward long-wave radiance is the largest in sunny and decreases in turn in a cloudy and rainy day.The time of the upward long-wave radiance reaches the ma...
