利用2001年6 - 12月和2002年丰水季（6 - 12月）的试验数据，对印度奥里萨邦Cuttack地区的IR 36品种的CERES-Rice模型（DSSAT v. 4.0）进行了标定和评价。该模型准确地预测了物候事件，即开花和成熟日期。不同施氮水平下的模拟籽粒产量与试验籽粒产量基本一致。在旱季（1 - 5月）对同一地点的历史气象资料（1983-2002年）应用大气褐云造成的太阳辐射胁迫评估模式发现，在不施肥条件下，入射太阳辐射减少30%，水稻产量减少4%。在相同的太阳辐射胁迫条件下，高施氮量（120 kg N ha -1）与不施肥条件相比，籽粒减产幅度高达12%。粮食产量的降低与较低的晶粒形成有关。
CERES–Rice model (DSSAT v. 4.0) was calibrated and evaluated for cultivar IR 36 at Cuttack, Orissa using experimental data of wet seasons (June-December) 2001 and 2002. The model accurately predicted phenological events i.e. flowering and maturity date. The simulated grain yield at different N levels was in close agreement with experimental grain yield. Application of the model for solar radiation stress assessment due to Atmospheric Brown Clouds on the same site during dry season (January-May) on historical weather data (1983-2002) revealed a reduction in rice grain yield by 4% with reduction of incident solar radiation by 30% under non-fertilized condition. Compared to non-fertilized condition, grain yield reduction was higher up to 12% with similar solar radiation stress under high rates of N application (120 kg N ha -1 ). The reduction in grain yield is associated with lower grain formation.
