volcanoes

Hello ,everyone: I am planning to conduct volcanic forcing experiments (e.g. 1815Tambora or 1991Pinatubo) with CESM2.1.3-CAM6 to study the influence of a large eruption on climate,. Hoewvwr, I am not sure how to add the needed volcanic forcing file, via ext_frc_specifier or...

I have previously been running the BWma1850 compset, where the point has been to run the CESM with my own volcanic forcing file (i.e. by creating a new VolcanEESM... in the stratvolc directory) such that the evolution of stratospheric aerosol from SO2 emissions are calculated by the model. The...

Hi, everyone. I plan to conduct some sensitive experiments related to volcanic eruptions with CESM1.2(CAM5) and CESM2.2(CAM6). I have known that sulfur dioxides on behalf of a volcanic eruption can be input to CESM-WACCM, while the computing resources of WACCM are too huge. I wonder how the...

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, Could someone confirm whether the SO2 external forcing (emissions-cmip6_SO2) includes both volcanic continuous (degassing) and explosive (eruptions) SO2 emissions? Mvh, Jeani

Dear members,I am using CESM 1.0.4 with CAM4 for my study.I have a doubt regarding the volcanic aerosol file used in the model. In the CAM4 description, it is specified that the volcanic stratospheric aerosols are comprised of 75% sulfuric acid and 25% water.The variable details, as given in the...

Dear Forum Members,I am using CESM 1.0.4 and CAM4 to study the effects of sulfate aerosols (both background and volcanic size) by prescribing them in stratosphere. 1) Could somebody provide a reference on how longwave and shortwave properties of sulfate aerosols are parametrised in the model...

Hi,I am running B1850C5 compset in CESM1.2.2, but I want let only volcanoe forcing go through their transient 20th Century forcing. Can I add the volcano forcing namelist into the user_nl_cam directly? Thanks!

Hi:I am running a user defined AMIP run upto current date. Model runs file unitl Dec 2013; but model fail on 14 january 2014. Error tracing show error in reading vlocanic aersol forcing which has data only upto Januray 2014.;*****************************incr_flnm: old filename =...

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...

Hi, every one    I ran a case using cesm1_0_3 with -res T31_g37 -compset B1850. I want to do a only time-varying volcano experiment. So I modified the Buildconf/cam.buildnml.csh script, and added a piece of code in it as follows:&prescribed_volcaero_nl prescribed_volcaero_datapath =...
