emissions

Hello CAM-Chem people! (Useful background information) I want to assess my understanding of a change I made to one of my model runs pertaining to sulfate emissions. I was looking to create a large crude plume of sulfate aerosols over the east coast of the United States. To do this I first...

Hi, In the input data repository (https://svn-ccsm-inputdata.cgd.ucar.edu/trunk/inputdata/atm/cam/chem/emis/emissions_ssp126/), I can see biomass burning (bb) and anthropogenic (anthro) emissions .nc files. I am wondering do these files include the emissions from agricultural activities. For...

Dear CESM land modeling community, We are seeking to archive hourly emissions from MEGAN 2.1 in CESM2.1.3 with CLM5. Using the standard outputs, we are seeing that we can get 10 different emissions (acetaldehyde, acetic acid, acetone, carene-3, ethanol, formaldehyde, isoprene, methanol...

Hello, I am interested in modeling discrete events that generate instantaneous emissions at altitude. I want to create impulse emissions which occur at a single instance, rather than over time. For context, I need to combine this emission with other emissions that use the 'cyclical' parameter...

Hi, I am trying to setup a WACCM run in CESM2.1.3 where instead of a fixed mixing ratio at the atmosphere lower boundary for CH3Cl, CH4, N2O, CO, and H2, I have a fixed flux for those species. I have done this before with CH4, and it required removing CH4 from flbc_list in user_nl_cam, adding it...

I would like to run the compset BRCP26C5CN with CAM5, but when I builded it the CESM told me that I was missing file https://svn-ccsm-inputdata.cgd.ucar.edu/trunk/inputdata/atm/cam/chem/trop_mozart_aero/emis/RCP26_mam3_pom_elev_2000-2100_c20130424.nc，RCP26_soag_1.5_surf_2000-2100_c20130424.nc...

Dear all, Is there any way in CESM where I can modify the agricultural ammonia and see how it can affect the ambient PM2.5 globally? I can find some emission files for ammonia from "bb" and "anthro" for different SSPs, but not NH3 solely from agriculture. Any hint/idea on how I can do this in...

In CESM1.2.2, does the aerosol emission inventory in MAM3 (CAM5) for year 2020 represent the average emission level between 2010 and 2030, or just the emission level in 2020? I noticed that the emission inventory gives data every 10 years (2010, 2020 and 2030). Thank you for help!

Hi all, I am running CESM2 in a CAM-chem configuration for the year 2050. I have set all surface emissions, lateral boundary conditions, and external forcing specifiers to 2050. However, I am having a problem setting the continuous volcanic emissions. I am aware that these are time averages of...

Hi, I didn't find the following files for SSP370 in the input data file (https://svn-ccsm-inputdata.cgd.ucar.edu/trunk/inputdata/atm/cam/chem/emis/emissions_ssp370/). Could you please let me know where can I find those files? missing data: C2H4_bb CB1_bb, CB2_bb OC1_bb OC2_bb I just found these...

Hello, Now, to investigate the effect of the aircraft's emission on the atmosphere, I run two CASEs: one with aircraft emission and one without the emission. The calculation conditions are below. COMPSET: FW1850 RES: f09_f09_mg17 RUN_STARTDATE: 2015-0101 STOP_N = 13 STOP_OPTION = nmonths...

Hi folks, I'm trying to do a set of simulations in CAM5, run in atmosphere-only mode (F_1850_CAM5 compset), that modifies the input emissions of DMS to reduce emissions in a specific region. I'm in search of information on the correct diagnostics for DMS and on how CAM5 handles DMS emissions so...
