    Can the ozone data from CESM2.1.3 WACCM FWsc2000climo be changed to four dimensions (nm,nlevel,nlat,nlon)

    The prescribed ozone data in CESM2.1.3 WACCM FWsc2000climo is zonal-mean of 5-day averages , is it possible to change this data to a four-dimensional (e.g., nmonth(12)*nlevel*nlat*nlon)? Besides, is "prescribed_ozone_file" and "prescribed_strataero_file" the same file? FWsc2000climo...

    Is it possible to run 2xCO2 in Bwma1850 compset?

    In an attempt to compare volcanic eruptions in different climate states I want to run the BWma1850 compset with doubled CO2 concentrations before I branch off and run my ensemble of volcanic eruptions experiments. (I have already been running these eruptions using the standard BWma1850 compset.)...

    CESM2 WACCM6 BWma1850 prescribed aerosols, *_logv and *_logm aerosol variables how are they created?

    To Whom this may concern, I have attached the version_info.txt and the user_nl_cam.txt (these are the user mods I have done). I also additionally modified the aerosoldep_monthly_1849_2000_1.9x2.5_c090803.nc to just include 1850 data, for various aerosol data. I am receiving the following...

    How to use specified aerosols, GHGs (CO2 & CH4), and ozone in CESM2-WACCM BWma1850 compset?

    To Whom this may concern, I have 12-month means (3-D fields, over 211 y of output) from the BW1850 compset that I would like to prescribe into the BWma1850 compset. I understand that I can use the "prescribed_aero_specifier", etc., "prescribed_ghg_specifier", etc., and...

    Is HONO (nitrous acid) represented in the WACCM6 tsmlt chemistry set?

    To Whom this may concern, Looking through the chem_mech.doc it appears that HONO (nitrous acid) is not represented as a chemical species in the model. I was wondering if there is any confirmation if that is correct, and if it is which documentation/papers should I look at? The compset used in...

    transient volcano forcing in WACCM

    Hi, We are trying to run a single forcing case using an 1850 compset and then letting only volcanoes go through their transient 20th Century forcing. We need to know which namelists to modify? Is the sad_file in the chem_inparm namelist the only file we need to modify or are other files involved...
