Name a unit designed for wet and dry bulb thermometers to protect temperature sensors from being affected by direct or reflected sunlight.

Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1 i.e. Stevenson screen.

  • The Stevenson screen is a specially designed unit that is used to protect the temperature sensors of wet and dry bulb thermometers from being affected by direct or reflected sunlight.
  • It ensures that the temperature readings are accurate by shielding the thermometers from external environmental factors like heat, which could distort the readings.
  • The screen consists of a wooden or metallic structure with slats to allow air circulation and prevent sunlight from directly reaching the thermometers.
  • This design is essential for maintaining the integrity of temperature measurements in meteorological observations.
