Rothermel (version 1.2)

scenarios: Moisture scenarios by Scott & Burgan (2005)

Description

A fuel Moisture Scenario is a set of fuel moisture values representing moisture condition of the surface fuel. Fuel Moisture Scenarios are useful for testing custom Fuel Models or developing fire prescriptions. For example, a moisture Scenario might be developed to represent a location's 90th-, 95th-, and 97th-percentile fire weather conditions (Andrews 2009)

Usage

data(scenarios)

Arguments

Format

A data frame with 16 observations on the following 12 variables.
Moist_1h
moisture of 1h fuel class on a dry weight basis [percent]
Moist_10h
moisture of 10h fuel class on a dry weight basis [percent]
Moist_100h
moisture of 100h fuel class on a dry weight basis [percent]
Moist_Live_Herb
moisture of herbaceous fuels on a dry weight basis [percent]
Moist_Live_Woody
moisture of woody fuels on a dry weight basis [percent]
