AB  - The study domain covered the Eastern region of Southern of Vietnam that includes 
      Ho Chi Minh City (HCMC) and five other provinces. Rice production in the domain 
      accounted for 13% of the national total with three crop cycles per year. We 
      assessed ozone (O3) induced rice production loss in the domain for 2010 using 
      simulated hourly surface O3 concentrations (WRF/CAMx; 4km resolution). Simulated 
      O3 was higher in January-February (largely overlaps the first crop) and 
      September-December (third crop), and lower in March-June (second crop). 
      Spatially, O3 was higher in downwind locations of HCMC and were comparable with 
      observed data. Relative yield loss (RYL) was assessed for each crop over the 
      respective growing period (105days) using three metrics: AOT40, M7 and flux-based 
      O3 dose of POD10. Higher RYL was estimated for the downwind of HCMC. Overall, the 
      rice production loss due to O3 exposure in the study domain in 2010 was the 
      highest for the first crop (up to 25,800metrictons), the second highest for the 
      third crop (up to 21,500tons) and the least for the second crop (up to 6800tons). 
      The low RYL obtained for the second crop by POD10 may be due to the use of a high 
      threshold value (Y=10nmolm(-2)s(-1)). Linear regression between non-null 
      radiation POD0 and POD10 had similar slopes for the first and third crop when 
      POD0 was higher and very low slope for the second crop when POD0 was low. The 
      results of this study can be used for the rice crop planning to avoid the period 
      of potential high RYL due to O3 exposure.
