title: Assessing current and future ozone-induced yield reductions for rice and winter wheat in Chongqing and the Yangtze River Delta of China.
abstract: Dose-response functions from China were employed to assess ozone (O3)-induced relative yield loss (RYL) for rice and winter wheat in Chongqing and the Yangtze River Delta (YRD) in 1990-2020, based on monitored and simulated O3 exposures. It shows that RYL for rice in Chongqing from 1990 to 1995 was 1.1-5.8% and would reach 10.8% in 2020, while for winter wheat it was estimated to be 0.2-9.8% in 1990 and would reach around 12.0% in 2020. In the YRD, RYL for rice was 2.5-6.6% from 1990 to 1999 and would reach 9.2% in 2020, while for winter wheat, RYL was estimated to be 7.1-8.4% based on simulated O3 dosages, while based on monitored O3 dosages, it had surpassed 8.4% and reached about 12.0% in 1999.
