Data Download:
===============================================================================

The files in this directory may be accessed by FTP download:

   ftp ftp.as.harvard.edu
   cd pub/geos-chem/data/GEOS_1x1/drydep_200203/

You may also use "wget" download:

   wget -r -nH "ftp://ftp.as.harvard.edu/pub/geos-chem/data/GEOS_1x1/drydep_200203/"



Files:
===============================================================================

drydep.coef  : Polynomial coefficents for dry deposition (from Baldocchi)

drydep.table : Lookup table that maps from Olson surface type indices
	       to the indices used in the dry deposition code; also
	       contains resistances for each deposition surface type. 
	
Both files are ASCII format.


Source:
===============================================================================

Both files are from the original dry deposition scheme by Daniel Jacob.


Notes:
===============================================================================

(1) drydep.coef  is read into GEOS-CHEM by routine "rddrycf.f"
    drydep.table is read into GEOS-CHEM by routine "modin.f"
