Hi,  
I also encountered zero sensitivity coefficients (O3 to NOx or VOCs emssions) when I ran CMAQv5.3.2 and v5.3.3 while I got too high second-order sensitivity coefficients using CMAQv5.4 as reported in [CMAQv5.4 HDDM gives too high second order sensitivity](https://forum.cmascenter.org/t/cmaqv5-4-hddm-gives-too-high-second-order-sensitivity/3722). I would be appreciate if someone could help us to solve the problem
