WRF-Chem Volcano output - Etna Summer 2012

Output from a model run of a modified version of WRF-Chem, which we refer to as WRF-Chem Volcano (WCV). At the time of submission of this dataset, these data were the basis of the modelling part of a paper submitted imminently to [Atmospheric Chemistry and Physics Discussions (ACPD)]: "Observation and modelling of ozone-destructive chemistry in a quiescent degassing volcanic plume".

The code of WCV is maintained here. Development of this code will continue after the submission of this repository, This branch is a permanent record of the code as used to create this dataset.
This is a simulation of the chemistry of the degassing plume of Etna in July/August 2012. This simulation includes bromine, chlorine and mercury chemistry. The time period modelled for the main and novolc runs is the 29 July - 01 August, however the first 24 hours of simulation are considered to be "spin up" and these data are not uploaded here. Other runs were begun from the state of the main  model run at 2012-08-01 00:00 and therefore only output for this one day exists.

All data here relates to domain "d04", which is the innermost nest (see Figure 3 of paper).

Data from multiple runs is uploaded here, see Table 2 of paper.

Overview of files

Output files: RUNNAME_wrfout_d04_YYYY-MM-DD_HH:MM:SS

Output data is contained in NetCDF files. Each file contains hourly snapshots of the 3D simulation with fields for various parameters. Most of the 4D (three spatial dimensions and time) variables record modelled mixing ratios of various gaseous species (in units ppm) and aerosol species (separated by species and size bin, in units ug/kg-dry-air). Many other variables are standard WRF-Chem output variables; please see WRF-Chem's documentation. If the meaning of a variable is unclear, please contact the author.

Each file covers a period of 24 hours.

Runs main, novolc and hal00 were run for the full model period. The other runs were run for 2012-08-01 only, beginning with the model state of main at 2012-08-01 00:00:00

WRF-Chem namelist files

namelist.wps is the input file used for the WPS pre-processor (common to all runs).

namelist.input is the input file used for WRF, this file is common to all runs with volcanic emissions. namelist.input_novolc is the input file used for the novolc run

PREP-CHEM SRC input files: prep_chem_sources_RUNNAME.inp

Input files for PrepChem for each run with volcanic emissions.
