我们模拟每年传入的太阳辐射的地形气候学的格兰德河流域在科罗拉多，美国每小时的总日射强度计测量结合卫星反射率数据和30米的数字高程模型内的地形太阳辐射算法。我们的研究结果表明，有很大的空间变化，在盆地内，即使在每年的整合长度，但每年，流域范围内的平均值是接近的日射强度计测量。16平方公里和100平方公里区域内的方差是该区域平均坡度的线性函数，表明可能对次网格单元变异性进行参数化。参考文献13篇。
We model the annual incoming solar radiation topoclimatology for the Rio Grande River basin in Colorado, U.S.A. Hourly pyranometer measurements are combined with satellite reflectance data and 30-m digital elevation models within a topographic solar radiation algorithm. Our results show that there is large spatial variability within the basin, even at an annual integration length, but the annual, basin-wide mean is close to that measured by the pyranometers. The variance within 16 sq km and 100 sq km regions is a linear function of the average slope in the region, suggesting a possible parameterization for sub-grid-cell variability. 13 refs.
