Which statement about V-Smoke is NOT true?

Which statement about V-Smoke is NOT true?

• A. It is a computer program
• B. It estimates smoke concentrations
• C. It uses static weather conditions
• D. It requires real-time weather data

Answer: (D)

V-Smoke is a computer model used to estimate how smoke from fires spreads and what concentrations people or areas might experience. It works by simulating the plume's transport and dilution through the atmosphere, based on inputs about the fire (emissions) and atmospheric conditions. You can run V-Smoke using static weather data—fixed values for wind, stability, temperature, and other factors—for planning or scenario analysis. That means you don’t have to rely on live, real-time weather to get useful estimates. Real-time or forecast weather can be used when available, but it isn’t a requirement for every run. That makes the statement about needing real-time weather data not true. The model is capable of operating with static weather inputs, which is why that option is the one that isn’t necessarily true. The other statements fit the model’s nature: it is a computer program, it estimates smoke concentrations, and it can use static weather conditions.
