PM2.5 Smoke Emission Per Ton Burned

Aggregate distinct measured consumed dry fuel classes and caller PM2.5 mass emission factors; grams/kg equals kg/tonne, and emitted mass is not dispersion, exposure or air-quality safety.

Description

Consumed dry fuel and mass emission factors can estimate emitted PM2.5 mass.

Consumed dry fuel and mass emission factors can estimate emitted PM2.5 mass. Grams per kilogram and kilograms per metric tonne have the same numeric factor.^[1]

Aggregate distinct measured consumed dry fuel classes and caller PM2.5 mass emission factors; grams/kg equals kg/tonne, and emitted mass is not dispersion, exposure or air-quality safety.

When to use PM2.5 Smoke Emission Per Ton Burned

Use this tool to aggregate distinct measured consumed dry fuel classes and caller PM2.5 mass emission factors; grams/kg equals kg/tonne, and emitted mass is not dispersion, exposure or air-quality safety.

Gather the tree inventory, plot measurements or model parameters. Check diameter, area, time and moisture conventions; keep paired observations aligned.

How to use PM2.5 Smoke Emission Per Ton Burned and understand its results

Gather the tree inventory, plot measurements or model parameters. Check diameter, area, time and moisture conventions; keep paired observations aligned.
Enter consumedFuelDryTonnes, pm25EmissionFactorsGramsPerKg using the field table and calculation rules, then run the tool.
Read totalPm25EmissionKg, consumedFuelWeightedEmissionKgPerTonne. The explanation below defines the units, signs, ordering and any flags or placeholder values.
If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.

Input field	Meaning	Value type; see rules below	Requirement
consumedFuelDryTonnes	Consumed fuel dry tonnes	list of number	Required
pm25EmissionFactorsGramsPerKg	Pm25 emission factors grams per kg	list of number	Required

Pair nonnegative dry fuel tonnes and nonnegative factors in g/kg with positive total fuel. Return total emitted kg and consumed-fuel-weighted kg/tonne.

Paired lists must be nonempty and have equal lengths.

PM2.5 kg=Σconsumed dry tonnes × emission factor g/kg

Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.

Output field	Meaning	Value type
totalPm25EmissionKg	Total pm25 emission kg	number
consumedFuelWeightedEmissionKgPerTonne	Consumed fuel weighted emission kg per tonne	number

Limitations and assumptions

Factors are supplied by fuel class. Dispersion, inhaled exposure and air-quality thresholds are not modeled.

Numeric inputs and returned numeric values must be finite; an unrepresentable returned value produces an error. Numeric lists are limited to 100,000 entries; the rules above may require smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.

Alternative or Complementary methods

Use Prescribed Burn Consumption Tonnes Per Unit Area: Difference matched pre/post dry-load measurements with physical area weights, retaining negative apparent consumption rather than clipping measurement/background changes; not a prescribed-burn recipe. For a complementary task, use Byram Fireline Intensity kW/m: Compute Byram heat-yield×consumed-fuel×front-spread fireline intensity using supplied dry fuel consumption, not full fuel load or a fire-danger/response recommendation.
