Correct option is A
Pyranometer (A) and Anemometer (B) are not directly involved in the global radiation balance.
Pyranometer measures solar radiation but does not influence or participate in the radiation balance itself.
Anemometer measures wind speed, which relates to atmospheric dynamics but not radiation balance.
Information Booster:
The global radiation balance ensures that incoming solar radiation is balanced with outgoing terrestrial radiation to maintain Earth's energy equilibrium.
Albedo affects how much sunlight is reflected; snow-covered regions have high albedo, while forests and oceans have low albedo.
Sensible Heat transfer is crucial in the Earth's energy cycle, especially in the atmosphere.
Pyranometers and anemometers are measurement tools, not phenomena involved in radiation balance.
Human activities, such as greenhouse gas emissions, can disrupt this balance, leading to global warming.
Additional Knowledge:
Albedo (C) and Sensible Heat (D), however, are key components:
Albedo influences radiation balance by determining the reflection of solar radiation from Earth's surface.
Sensible Heat plays a role in transferring energy between Earth's surface and the atmosphere.
