Hello, Is there any tool to prepare NEI2017 12km ocean\_cl2 for domain which is larger than 12US1. Thank you in advance! ---

I was not sure if you need help in creating the ocean file for the larger domain or you need help in adding oceanic Cl2 emissions to the emission files for the larger domain. If you need help in creating the ocean file for the larger domain, then I can help you. I need your GRIDESC file. If you want to add oceanic Cl2 emissions, then you can write a simple Fortran code to add oceanic Cl2 emissions to the file. I may have other code that I prepared many years ago to modify emissions in a file which can be revised to add oceanic Cl2 emissions to a file. Thanks, Sarwar ---

Hi Sarwar, Thank you for your reply! I am using NEI2017, I need ocean\_cl2 file for a larger 12km domain, so I think I need your help to create it. Hope it won’t take up much of your time. The GRIDDESC is ‘US12KM\_444X336’, ! 12km national US ’ ’ ‘LAM\_40N\_97W’ 2 33.000 45.000 -97.000 -97.000 40.000 ’ ’ ‘US12KM\_444X336’ ‘LAM\_40N\_97W’ -2736000.000 -2088000.000 12000.000 12000.000 444 336 1 ’ ’ Thanks a lot! ---

Thanks, I received the GRIDDESC file and will work it. ---

I generated the ocean file. Please send me your email address; I will send you the file. Thanks, Sarwar
