Mass transfer model for ammonia loss from animal slurry storage

Summary

AMOSTO.xlsx is a spreadsheet implementation of a simple mass transfer model for estimating ammonia volatilization from animal slurry storage structures. It can be used to calculate emission at a monthly resolution based on climate and slurry characteristics. The model is described in detail in a paper in Biosystems Engineering:
