AeroCom Control 2016

The model versions used for the different experiments are often not easily comparable. New model versions should be documented regularly to establish a state of the art comparison yearly. For this purpose AeroCom offers a semi-automatic platform with visualization via the AeroCom webinterface. Evaluation with surface observations and Aeronet observations will complete the documentation of emissions, removal, burden, lifetime of the major aerosol species.

In 2016 additional motivation we try to revisit the AeroCom evaluation done in 2006. Also - several experiments have been launched (in-situ optical properties, size, biomass burning, dust, nitrate and detailed 3h hourly evaluation to remote sensing data) which should be linked through common output. Also - models prepare for CMIP6 and might be interested in quick feedback.

Deadline for model submissions to be analysed before the Beijing AeroCom workshop: 1.September, on the condition that formatting and naming of files follows the instructions below.
Michael Schulz, michael.schulz@met.no

Experiment name: AP3-CTRL2016-PD and AP3-CTRL2016-PI

Two experiments:
One with current eg HTAPv2 emissions (*-PD)
One with preindustrial emissions (*-PI)
OR better using the new CMIP6 emissions….

OFFICIAL DATA REQUEST THROUGH CMIP6: CMIP6 data request

The directory /media/scratch/incoming/AEROCOM-P3-AUTO-UPLOAD allows for automatic incorporation into the AeroCom database and workup. Uploaded files are processed automatically by the AeroCom tools and transferred into the AeroCom phase III data directory. (Still in testphase, please send an email also to michael.schulz@met.no and anna.benedictow@met.no)

If correct in format and with correct filenames, results uploaded here will be processed over night and appear after few days as image catalogue on http://aerocom.met.no/cgi-bin/aerocom/surfobs_annualrs.pl?PROJECT=AEROCOM&MODELLIST=AEROCOM-Phase-III

Short Recipe (Long version: https://wiki.met.no/aerocom/data_submission)

1) Name files according to HTAPII/AeroComPhaseIII standards. One file per year and variable
aerocom3_<ModelName>_<ExperimentName>_<VariableName>_<VerticalCoordinateType>_<Period>_<Frequency>.nc
for example
aerocom3_GOCART_AP3-CTRL2016_od550aer_Column_2010_monthly.nc

2) Check for cf compliance some files (http://cf-checker.met.no/upload)

3a) obtain account on aerocom-users server

3) create directory on aerocom-users.met.no server:
/media/scratch/incoming/AEROCOM_AUTO_UPLOAD/{MODELNAME}/renamed/
Use exactly the same model name as used for file names. Attention to lower&upper case!!

4) Put files directly into this “renamed” directory.
And send e-mail to jan.griesfeller and michael.schulz and anna.benedictow @met.no
