  The purpose of this document is to provide technical information on version 3.0 of the Terrestrial Investigation Model (TIM v.3.0). TIM derives quantitative estimates of the probability (or likelihood) and magnitude of mortality to birds (of the same species) exposed to the simulated pesticide. This document describes how TIM derives joint distributions of exposure and toxicity to calculate the risk of mortality to birds.
