Why is WRF-Chem not reading my emissions data?
I could run model, i just had to change a bit the namelist. I added three parameters:io_form_auxinput5 = 2,auxinput5_inname = 'wrfchemi_d$&lt;domain&gt;$_$&lt;date&gt;$'  and frames_per_auxinput5                = 168. (168 hours of emissions and hours of simulation)
