Boundary Conditions and Input Files for SOCOL

The boundary conditions are available for our standard model resolutions T31L39 and T42L39. Most input data are also available in T42L90. A few data sets are further available in T63L47 (note: SOCOLv3 never ran in this resolution).

Further information on CCMI-related boundary conditions can be found here: https://www.sparc-climate.org/fileadmin/customer/6_Publications/Newsletter_PDF/40_SPARCnewsletter_Jan2013_web.pdf

NOTE: Initial and boundary conditions for ECHAM5-MPIOM used in the FUPSOL project are stored here on Euler: /cluster/work/climate/stenkea/echam5/input/

Emissions

Our input files include monthly mean emission fluxes at the surface. Units are usually [g/cm2/s] or [kg/m2/s] (ATTENTION: correct conversion factor to mixing ratio must be applied in socol_boundary_conditions.f90) (subroutine set_socol_bcond_fluxes). The emissions are assumed to be representative for the middle of the month. To avoid jumps from month to month, a linear interpolation in time between previous, present and next month is applied during a model simulation.

Regridding procedures

For horizontal regridding of original emission fluxes to SOCOL's horizontal grid the tool ncregrid can be used. The source code, binary and several run scripts can be found here: /home/stenkea/ncregrid/

Details about how to use ncregrid can be found in the manual. An example script for regridding CO and NOx emission fluxes is given here.

For the final preparation of input files for SOCOL ncl can be used, e.g.

CO and NOx

The input files include CO and NOx surface emissions [g/m2/s] as well as aircraft NOx emissions [molec/cm3/s] on pressure levels. We assume a fraction of 90% NO in NOx emissions and 10% of NO2, respectively (parameters nofracnox_bcond and no2fracnox_bcond in mo_socol_constants.f90)

NMHC

NMHC emissions are lumped emissions and only used as an additional indirect source of CO, that is, a certain fraction of the NMVOC emis- sion is directly added to CO. For the CCMI set up the conversion factors are 1.0 for anthropogenic NMHCs, 0.31 for biomass burning, and 0.83 for biogenic sources (Revell et al., 2015). The conversion factors are hard-wired in src/socol_boundary_conditions.f90.

Updates for downloading ERA5 data

ERA-Interim is only available up to 31 August 2019, after which it has been superseded by the ERA5 analysis https://www.ecmwf.int/en/forecasts/datasets/reanalysis-datasets/era5. Therefore, nudging runs after August 2019 will require the use of ERA5 analysis to produce nudging files
ERA5 can be downloaded from the Climate Data Store (CDS), with the full instructions shown here : https://confluence.ecmwf.int/display/CKB/How+to+download+ERA5
The CDS API must be installed on your machine to download ERA5 data. For the IAC IT system, this can be done by creating a new environment and installing the CDS API package: https://wiki.iac.ethz.ch/IT/PythonFAQ#How_can_I_create_my_own_environm
A new version of the python script to download the necessary ERA5 data programatically: retrieve_ERA5.py
Be aware of the long download times for the ERA5 data, due to the queueing system. One month of data required for nudging takes around 1-2 hours to download.

SOCOL-AER radiative lookup tables:

SOCOL-AER uses a lookup table approach to calculate the aerosol radiative properties (extinction coefficients, single scattering albedos, asymmetry factors) from the particle size distribution for 22 wavelength bands. The original lookup table for SOCOL-AERv1 is the file band_echam5_aer_2012.dat. A new lookup table was created for SOCOL-AERv2 since the aerosol size distribution is tracked with dry aerosol radius, and relative humidity is required to calculate the wet aerosol size distribution. Beiping Luo calculated a full lookup table with Mie theory at 95 temperatures and 1001 relative humidities (band_echam5_pw_socol.dat). Since the size of this file is rather big (3.6 GB), it slowed down the model significantly. Therefore the lookup table was condensed to only using 10 temperatures and 76 relative humidity values, chosen so that the change in aerosol sulfate weight fraction between subsequent relative humidity entries is at most 0.01 (band_echam5_pw_socol_condense.dat). The script used to do this file editing is condense_lookup_T.sh.

Tropospheric Aerosols

SOCOL reads mass mixing ratios of 10 tropospheric aerosol types as function of (TIME, LEV, LAT, LON) for radiation and heterogeneous chemistry (N2O5? hydrolysis): Methane sulfonate (MSA), Sulfate (SULFATE), accumulation mode dust (0-1 µm) (DUSTACCU), coarse mode dust (1-2 µm) (DUSTCOARSE), accumulation mode sea salt (0-1 µm) (SEASALTACCU), coarse mode sea salt (1-10 µm) (SEASALTCOARSE), hydrophilic and -hobic organic and black carbon (OCPHILIC, OCPHOBIC, BCPHILIC, BCPHOBIC)
