Research Interest: 1, Ozone Depletion Substances (ODS); Greenhouse Gases (GHG) 2, Compiling inventory (sectoral, regional, national scale) 3, Atmospheric observation (On-line, Off-line, GC/MS analysis) 4, Transport simulation (Backward, Forward) 5, Inverse modeling (Bayesian inversion, global, regional)

Near-real-time Global Transport Forecast:
Simulation of tracer gases dispersion and transportation in ca. 5 days from now on. (construsting, here just a test) please clickHere

Forecasting Concentration at Specific Station:
We use the Meteorological data and emission information to simulate the concentration at the specific observation station. Even we want to forecast the concentrations at this site for a next period, e.g., three days, to give information to the observation people at the station. One valuable application is that forecasted concentration information will of course give instruction the observer a idea of when it is a good time (e.g. high concentration time)to take POPs samples, since analysis of POPs samples are quite expensive.

Description for retrieval of meteorological NCEP Final Analysis (FNL) data and running modified FLEXPART (called FLEXPART FNL version) using FNL data. Here are the instructions about downloading FNL data: 1. Go to website: http://rda.ucar.edu/datasets/ds083.2/ 2. Log in with your ucar account, or create one for free. 3. Click the "Data Access" tab -> Decide GRIB1 or GRIB2 data to download, and click "Web File Listing" link -> Click "Complete File List" link. 4. Choose and click Group ID (year), and select Subgroup ID (month) you want. 5. Click “Csh Download Script”, highlight this script by Select All, Copy and Paste it into a file (namely filename.csh); Change the “set pswd = $1” to your password “set pswd = xxxxx”. Do not do these in Window system but in linux to avoid executing errors. 6. Make the file executable (chmod 700 filename.csh) and run it on command line (./filename.csh). Here are the instructions about running FLEXPART using FNL data: 1. Note that when you produce the AVAILABLE file, filenames of FNL data in 20080930 switch from fnl_20080930_06_00 to fnl_20080930_12_00_c. 2. There is a modified FLEXPART version for FNL in http://zardoz.nilu.no/~fang/FLEXPART9.02_FNL/ 3. In the par_mod.f90, set the nxshift=0 and nuvzmax, nwzmax, nzmax=26. 4. Use command “make -f makefile.fnl_gfortran” to compile the scripts. (Three files are different from the gfs version: makefile.fnl_gfortran, gridcheck_fnl.f90, par_mod.f90). 5. Run “FNL_FLEXPART_GFORTRAN”.
