Lookup tables for H2SO4-H2O binary and H2SO4-H2O-NH3 ternary homogeneous and ion-mediated nucleation

2019/10/10

This directory contains fortran code and lookup tables for calculating
nucleation rate for the following four nucleation mechanims:
1. H2SO4-H2O binary homogenous nucleation (BHN),
2. H2SO4-H2O-NH3 ternary homogeneous nucleation (THN),
3. H2SO4-H2O-Ions binary ion-mediated nucleation (BIMN), and
4. H2SO4-H2O-NH3-Ions ternary ion-mediated nucleation (TIMN)

Files included in the package:

YBHN/: BHN code and lookup table
YTHN/: THN code and lookup table
YBIMN/: BIMN code and lookup table
YTIMN/: TIMN code and lookup table

nucl_XXX_mod.f (XXX = BHN, THN, BIMN, TIMN): Stand alone module for XXX rate calculation.

mainXXX.f: Test program to demonstrate how the lookup table is used.

inputXXX.dat: Example input data for testing the code and lookup table.
outputXXX.dat: Example output after running the test code

Use "f95 *.f" to compile and get executable program a.out

To run the test program:

>a.out

For your reference, output of running the program on my workstation has been saved to outputXXX.dat.

I hope that the comments provided in the subroutines make
the code self-explanatory. Contact me if you have questions.

Enjoy and have fun!
