PREP-CHEM-SRC is a pollutant emissions numerical too developed at CPTEC/INPE whose function is to create data of atmospheric pollutant emissions from biomass burning, photosynthesis or other forest transformation processes, combustion of oil-based products by vehicles or industry, charcoal production, and many other processes.
The system is maintained and developed at CPTEC/INPE by the GMAI group, which not only updates versions of data such as EDGAR, RETRO, MEGAN, etc., but also implements new functionalities such as volcanic emissions which is present now in this version.
The purpose of PREP-CHEM guide is to present how to install, compile and run the pre-processor. Finally, the steps for utilizing the emissions data in the BRAMS, WRF-Chem and FIM-Chem models are presented.
We recommend that you read the article “PREP-CHEM-SRC – 1.0: a preprocessor of trace gas and aerossol emission fields for regional and global atmospheric chemistry models” (Freitas et al., 2010 – here).

Biomass data. 3bbem emissions biomass data are composed by MODIS, DSA and GOES(WF_ABBA). You can also can find more data at these sites:
Fire spots files from ABBA/GOES 15 – North and Central America (only the last 7 days):
GOES-16 officially replaced GOES-13 as GOES-EAST on December 19, 2017.

MODIS Global data from the site below must be treated in one software that will be turned avaiable in brams site in the future. If you need some MODIS data, you may request to us for some specific period.
After generating the data of atmospheric pollutant emissions by the PREP-CHEM software, it’s necessary to include chemical species to initial conditions and atmospheric boundary.
For that purpose, DPREP-CHEM software must be used to include the chemical species to initial conditions and atmospheric boundary in the format required by the model.
The boundary and initial condition atmospheric files are converted files from Global GFS to the required format for DPREP-CHEM. The conversion of files is done by GeraDP program, which is also available at the Atmospheric section in this page. Please refer to the Atmospheric section for more information.
