Troubleshooting modifications made to the MEGAN climate-modeling program to encompass specific extensions to the input data. The project examined the effect of gas emissions by vegetation.
openSUSE Linux, GNU FORTRAN.

I ported a suite of legacy numerical bio-assay programs from PDP-11 FORTRAN 4 to GNU FORTRAN 2003 on both SPARC Solaris and Intel Linux boxes. The original programs would not produce the correct output when just built on the modern boxes. My job was to ensure that the programs produced defined results for defined input data so that their correctness was verified.
Fixed bugs and errors during the port. Re-implemented the floating-point logic to avoid bogus comparisons for equality.
Provided FORTRAN consultancy to the scientists .
