Question

Match List-I with List-II

Choose the correct answer from the options given below:

• (A) - (I), (B) - (II), (C) - (III), (D) - (IV)
• (A) - (I), (B) - (III), (C) - (II), (D) - (IV)
• (A) - (II), (B) - (I), (C) - (IV), (D) - (III)
• (A) - (III), (B) - (IV), (C) - (I), (D) - (II)

Hint:

To solve this quickly, associate standard prefixes:
- "Pyro" relates to high thermal/solar radiation (Pyranometer \(\rightarrow\) Shortwave).
- "Quantum" refers to photons (Quantum sensor \(\rightarrow\) PAR).

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
Agro-meteorological monitoring utilizes specialized instruments to capture physical weather variables, solar radiation properties, and atmospheric moisture states.

Step 3: Detailed Explanation:
Let us match each instrument with the parameter it measures:
1. Wind vane (A): A mechanical pointer designed to rotate freely to align with the wind, indicating Wind direction (II).
2. Line Quantum sensor (B): Designed to measure photosynthetic photon flux density (PPFD) within canopy environments, capturing PAR (I) (Photosynthetically Active Radiation).
3. Pyranometer (C): An instrument designed to measure hemispherical solar shortwave radiation flux density, capturing Shortwave radiation (IV).
4. Hygrometer (D): An instrument used to determine the water vapor content of the atmosphere, measuring Relative humidity (III).
This gives the correct sequence: (A) - (II), (B) - (I), (C) - (IV), (D) - (III).

Step 4: Final Answer:
The correct option is 3, which corresponds to (A) - (II), (B) - (I), (C) - (IV), (D) - (III).
