What is it

Dead fuel moisture responds solely to ambient environmental conditions and is critical in determining fire potential. This library estimate the percentage of Dead Fuel Moisture Content (DFMC) (< 6mm) for a prediction input values.

It can be used both in the browser and in Node.js.

Usage

import { estimateDFMC } from 'dfmc-wildfire-calculator';
console.log(estimateDFMC("15:00", 2, "12:00", 21, 12, "Exposed", 13, "W")); // print 4 => 4% (DFMC with <6mm)

const wildfire = require('dfmc-wildfire-calculator');
console.log(wildfire.estimateDFMC("15:00", 2, "12:00", 21, 12, "Exposed", 13, "W")); // print 4 => 4% (DFMC with <6mm)
