B1850 N deposition

[yuecheng]

I am running the B1850 case of CESM, and I want to output the N deposition data, but I find that B1850 does not seem to turn on nitrogen chemistry, how should I turn on it? What do I need to change?

I am moving this to CAM-Chemistriy.

You probably need BGC active. Look at the compset's long name in README.case in your case's directory to see whether it includes BGC (CN may be ok, too). If it does, then I hope that you will find the output that you asked about in clm's history as NDEP_TO_SMINN.

The long name of my compset is 1850_CAM60_CLM50%BGC-CROP_CICE_POP2%ECO_MOSART_CISM2%NOEVOLVE_WW3_SIAC_SESP_BGC%BDRD.There is no output of N sedimentation in the CAM model, and I did not find any data on N emissions in the input emission source data.What should I do next? I want to output N settlement data in CAM and use the N settlement values in CLM.

From your response I gather that you did not look for the variable NDEP_TO_SMINN in CLM's output. That's still my recommendation.
