Searching the database¶
For all kinds of searches use acccmip6 -o S and then add in the optional arguments according to your need.
Optinal arguments 1¶
Use these arguments with any combination and in any sequence.
-m: takes model names-e: takes experiment names-v: takes variable names-f: takes frequency-r: takes realm name
General usage
acccmip6 -o S -m MIROC6 -v vas -f mon -r atmos
General output
TIPS: Use the check (-c) argument to check your inputs.

Allows multiple inputs: takes comma (,) separated multiple items
acccmip6 -o S -m MIROC6,CanESM,CNRM-CM6-1-HR -v va,ua -e ssp245-aer,hist-piAer
Allows list inputs: this is useful since the acccmip6 outputs in list format
acccmip6 -o S -e ['ssp245-GHG','historical'] -v ['hfls','hfss'] -f mon
Recommended: Use inputs within a ‘ ‘
acccmip6 -o S -m 'MIROC6, CanESM, CNRM-CM6-1-HR' -e '['ssp245-GHG', 'historical']' -f mon
Optional arguments 2¶
-c: ‘yes’ to check the inputs under optional argumetns 1. Searches through the servers and checks whether the input items are available or not.
General usage
acccmip6 -o S -m MIROC6 -v vas -f mon -r atmos -c yes
General output
TIPS: If you are not sure about what you are looking for use CMIP6DB module
to look for currently available models/experiments/variables and so on . . .

Get suggestions: use the -c argument when in doubts whether any input item is available in the current database.
acccmip6 -o S -m IPSL -c yes

Optional arguments 3¶
-desc: ‘yes’ to get the description of the experiments searched with-eargument. The descriptions comes at the end of the general search results.
general usage
acccmip6 -o S -e hist-piNTCF,hist-piAer -v vas -m MIROC6 -desc yes
General output

< < < Here are the experiment descriptions > > >
hist-piNTCF:
Impose historical WMGHG and halocarbon concentrations. Near Term Climate Forcers
(NTCFs: methane, tropospheric ozone and aerosols, and their precursors), to be
fixed at 1850 emission levels. These simulations parallel the "CMIP6 historical",
and differ only by fixing the anthropogenic emissions or concentrations of a
specified class of species. All other forcing agents must evolve as in "CMIP6 historical".
hist-piAer:
Historical WMGHG and Halocarbon concentrations. Historical ozone precursor emissions
(e.g. NOx). Aerosols and aerosol precursors fixed at 1850 emission levels.
Extra arguments¶
Use these optional arguments with in addition to Optional arguments.
-rlzn: select a realization-skip: skip items during download-time: ‘yes’ print out all available time periods
general usage
acccmip6.py -o S -v pr -e historical -f mon -m NorESM2-LM -time yes
general output: Avalable time periods are 1850-1859, 1860-1869 and so on until 2010-2014.
TIPS: Use the check (-c) argument to check your inputs.

-yr: select data for a specific time period
general usage: To download only the first 10 years (e.g. 1850-1859), use -yr 10 or the last 5 years (e.g. 2010-2014), use -yr -5.
python acccmip6.py -o S -v pr -e historical -f mon -m NorESM2-LM -yr -5 -time yes
general output: Note that the number of files is reduced from 51 to 3! This is very useful if the the data are as frequently chunked as this particular example. -yr 11 will download the 1850-1859 and 1860-1869 chunks. So, even though the user needs only the first 11 years of data, the package is limited to download whatever chunk is available to fullfill that 11 years of time period.
TIPS: Use the check (-c) argument to check your inputs.
