Equilibrium moisture content (EMC) of dead fuels as a function of temperature and relative humidity per the NFDRS (Cohen & Deeming 1985), page 1, Eqs. 1a/1b/1c. Migrated from WildlandFire.jl@126976f2 src/nfdrs.jl:79 (`EquilibriumMoistureContent` @component). Observed-only: TEMP and RH are inputs (parameters); EMC is the algebraic output.

Herbaceous fuel moisture content (MCHERB) per NFDRS Cohen & Deeming (1985), pages 6-8. Migrated from WildlandFire.jl@126976f2 src/nfdrs.jl:426 (`HerbaceousFuelMoisture` @component). Calculates moisture stages (pregreen, greenup, green, transition, cured/frozen) based on climate class, 1000-hr moisture, and seasonal flags.

100-hour timelag dead fuel moisture content per the NFDRS (Cohen & Deeming 1985), page 5. Migrated from WildlandFire.jl@126976f2 src/nfdrs.jl:279 (`HundredHourFuelMoisture` @component). State-variable model: MC100, EMCBAR, BNDRYH are time-indexed state variables with daily discrete update equations.

Live fuel moisture of extinction (M_x,live) from dead-fuel moisture, dead-to-live effective load ratio, and dead fuel moisture of extinction. Migrated from WildlandFire.jl@126976f2 src/rothermel.jl:367 (`LiveFuelMoistureExtinction` @component). Observed-only: Mx_dead, W_ratio, Mf_dead are inputs (parameters); Mx_live is an algebraic output. Implements Eq. M_x,live, Table 6b in Andrews (2018) RMRS-GTR-371.

1-hour timelag dead fuel moisture content per the NFDRS (Cohen & Deeming 1985), page 3. Migrated from WildlandFire.jl@126976f2 src/nfdrs.jl:149 (`OneHourFuelMoisture` @component). Observed-only: EMCPRM, MC10, use_fuel_sticks, is_raining are inputs (parameters); MC1 is the algebraic output.

10-hour timelag dead fuel moisture content per the NFDRS (Cohen & Deeming 1985), page 4. Migrated from WildlandFire.jl@126976f2 src/nfdrs.jl:207 (`TenHourFuelMoisture` @component). Observed-only: EMCPRM, use_fuel_sticks, WT, AGE, CLIMAT are inputs (parameters); MC10 is the algebraic output.

1000-hour timelag dead fuel moisture content per the 1978 NFDRS (Cohen & Deeming 1985), basic equations. Migrated from WildlandFire.jl@126976f2 src/nfdrs.jl:354 (`ThousandHourFuelMoisture` @component). Algebraic state-variable model: BNDRYT (today's boundary value) is computed from precipitation duration and the 24-hour average EMC; MC1000 is updated from the previous day's value (PM1000) using the 7-day boundary average (BDYBAR) and a fixed 1000-hour response coefficient.

Woody fuel (1000-hour) moisture content per NFDRS (Cohen & Deeming 1985), pages 8-9.
