I was asked by my prof to work on this cropping system model which takes soil,weather and crop files as input from every place around the world and give out the estimated plant growth for those values. This software takes input as daily data files now he asks me to develop the code in such a way it takes hourly inputs.It has about 100 .for files in it can some one help me im new to FORTRAN.What do you think might be the changes required to satisfy his condition. I dont really know where to start, I can hardly understand the code ,thanks
