Hi,
I am using the WRF-CHEM to do runnings. Now I can just create three single emission files contained all simulated periods for the three domains instead of separate hourly data files (e.g. wrfchemi_d01_2010-05-01_08:00:00, wrfchemi_d01_2010-05-01_13:00:00, hundreds of files for a long-term simulation). My namelist.input is provided here.
Two puzzles are concerned:
1) the model runs smoothly without any errors happened while using the single emission file, I am not sure whether the model reads and recognizes the three integrated emission files.
2) interestingly, the model can obtain 10 days simulated result by only employing a 24-h emssion file (an integerated file containing 24-h), is it related to the namelist.input configurations?
Any available responses are grateful！
