• Global Solar Energy Arrival Rate at Earth's Surface:
• Solar Influx Magnitude:
• The solar constant at the top of the atmosphere is $S_0 \approx 1361\text{ W/m}^2$.
• The cross-sectional solar disc intercepted by Earth is $\pi R_e^2$, receiving total power of $\approx 1.74 \times 10^{17}\text{ W}$ ($174\text{ PW}$).
• After atmospheric scattering, reflection, and absorption, approximately $70\%$ of this solar energy transmits into the Earth system, delivering radiant power to the planet at a continuous rate on the order of $10^{16}\text{ W}$ (approximately $1.0 - 1.2 \times 10^{16}\text{ W}$ terrestrial flux across continental land and water surfaces).
• Conclusion: 10$^{16}$ W (Option 3).

Correct option: (3) 1016 W
