Description
Return deposition flux and accumulated amount.
Atmospheric reaction, partitioning and deposition terms depend on supplied rates, spectral coordinates, coefficient definitions and transport assumptions. One bin or first-order factor is distinct from a complete chemical mechanism, evolving plume or verified treatment/exposure outcome.
Return deposition flux and accumulated amount.
When to use this tool
Use Deposition Velocity Flux Concentration Term when evaluating the stated atmospheric reaction, photolysis, partitioning or transport term.
How to use the tool and how it works
- Enter depositionVelocity, concentration, area, duration. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read arealFlux, depositedAmount. Use the output convention below.
Return deposition flux and accumulated amount. Require nonnegative depositionVelocity, concentration, area and duration; arealFlux = velocity*concentration, amount = flux*area*duration.1

| concentration | Concentration | Required. Finite number; minimum 0. |
| area | Area | Required. Finite number; minimum 0. |
| duration | Duration | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| arealFlux | Areal Flux | Required. Finite number. |
| depositedAmount | Deposited Amount | Required. Finite number. |

}Limitations and assumptions
- This assumes constant supplied deposition and concentration without resuspension; no environmental target, actual deposition or acceptable exposure is determined.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use verified coefficients and a complete suitable chemical/transport or spectral model, including changing conditions and omitted processes, for environmental conclusions.
