Question 1 of 5
1. Question
Q.1) Consider the following statements regarding the SkyCast System:
- It has been developed under Mission Mausam of the Ministry of Earth Sciences.
- The scientific foundation of the system is the Winter Fog Experiment (WiFEX).
- The Radar Wind Profiler measures atmospheric parameters up to nearly 10 km altitude and forms the core of the system.
- The system is designed primarily for long-range weather forecasting extending beyond seven days.
Which of the statements given above are correct?
Correct
Q.1) Solution (a)
Explanation:
- SkyCast is India’s first integrated aviation weather monitoring system developed under Mission Mausam.
- Its scientific foundation lies in WiFEX, initiated by IITM and IMD at IGI Airport.
- The Radar Wind Profiler forms the core observational component and helps monitor wind speed, turbulence, vertical velocity and boundary-layer dynamics.
- While the integrated system monitors atmospheric conditions from the surface to nearly 10 km, its primary utility lies in nowcasting and short-range aviation weather intelligence, especially for fog, turbulence, icing potential and wind shear.
- Statement 4 is incorrect because SkyCast is not intended for long-range forecasting; it provides very short-range operational forecasts and alerts, often within a few hours.
Why this question?
Tests distinction between nowcasting and long-range forecasting.
Why important for UPSC?
Increasing focus on weather technologies and disaster forecasting.

Question 2 of 5
2. Question
Q.2) With reference to the Banni Grassland ecosystem, consider the following statements:
- Chhari Dhand is a Ramsar Site situated within the Banni landscape.
- Prosopis juliflora is an invasive species that has significantly altered the grassland ecology.
- Solar photovoltaic projects necessarily require Environmental Impact Assessment under the EIA Notification, 2006.
- Maldharis are predominantly pastoral communities inhabiting the region.
Which of the statements given above are correct?
Correct
- Q.2) Solution (a)
Explanation:
- Banni Grassland in Kachchh hosts Chhari Dhand, a Ramsar-recognized wetland ecosystem.
- The region’s ecology has been heavily influenced by Prosopis juliflora, an invasive species often called “gando baval.”
- Maldharis, including Rabaris and Fakirani Jats, are traditional pastoralists dependent on grazing landscapes.
- Statement 3 is incorrect because solar photovoltaic projects were exempted from mandatory EIA requirements through a MoEFCC Office Memorandum (2017).
UPSC often frames questions where environmental protection and renewable energy objectives intersect, making knowledge of such regulatory exemptions important.
The question also tests understanding of ecological, social and policy dimensions together.
Why this question? Combines ecology, environment law and community livelihoods.
Why important for UPSC? Renewable energy versus conservation is an emerging theme.

Question 3 of 5
3. Question
Q.3) Consider the following statements regarding the Logistics Port Performance Index (LPPI):
- It was launched under the Sagar Aankalan framework.
- It evaluates performance across dry bulk, liquid bulk and container cargo segments.
- Equal weightage is assigned to absolute performance and year-on-year improvement.
- Air cargo volume is one of its key assessment parameters.
Which of the statements given above are correct?
Correct
Q.3) Solution (b)
Explanation:
-
- LPPI is India’s first national benchmarking framework for ports and was launched under the Sagar Aankalan framework.
- It assesses performance in three cargo categories: dry bulk, liquid bulk and container cargo.
- The methodology assigns equal importance to current performance and improvement over the previous year, encouraging both efficiency and progress.
- Air cargo volume is unrelated to LPPI because the index specifically measures maritime port performance.
UPSC frequently introduces an unrelated but plausible parameter to test conceptual clarity.
Knowledge of logistics reforms has become increasingly important due to multimodal connectivity and maritime sector expansion.
Why this question?
Introduces a classic UPSC “one unrelated parameter” trap.
Why important for UPSC?
Ports and logistics are critical growth sectors.

Question 4 of 5
4. Question
Q.4) Consider the following statements regarding the Border Security Force (BSF):
- It was raised following the 1965 India–Pakistan War.
- It functions under the Ministry of Defence.
- It is governed by the Border Security Force Act, 1968.
- Its jurisdiction for search, seizure and arrest has been expanded in certain border states.
Which of the statements given above are correct?
Correct
Q.4) Solution (b)
Explanation:
- BSF was established in 1965 after the India–Pakistan conflict and is governed by the Border Security Force Act, 1968.
- It functions under the Ministry of Home Affairs, not the Ministry of Defence, making Statement 2 incorrect.
- The force’s jurisdiction for search, seizure and arrest has been expanded from 15 km to 50 km in certain border states.
UPSC often tests CAPFs through ministry-force mismatches because aspirants frequently confuse administrative control with operational roles.
Understanding the distinction between Army, CAPFs and state police organizations is essential for internal security questions.
Why this question?
Exploits common confusion between MHA and Defence Ministry.
Why important for UPSC?
Internal security and CAPFs remain core topics.

Question 5 of 5
5. Question
Q.5) Match List I with List II and select the correct answer using the code given below:
List I List II A. GFAS 1. Acoustic wind profiling B. SODAR 2. Fog droplets and aerosol interactions C. Lidar Ceilometer 3. Cloud base and vertical fog structure D. Radar Wind Profiler 4. Wind speed, turbulence and vertical velocity Code:
Correct
Q.5) Solution (a)
Explanation:
- GFAS (Ground-based Fog Aerosol Spectrometer) measures fog droplets, aerosols and their interactions.
- SODAR (Sonic Detection and Ranging) is an acoustic remote-sensing system used for wind profiling.
- Lidar Ceilometers measure cloud-base height and monitor the vertical structure of fog.
- Radar Wind Profilers provide information on wind speed, direction, turbulence and vertical velocity.
UPSC frequently tests scientific instruments through matching exercises where all options appear plausible.
The key is understanding the physical principle behind each technology—acoustic, optical, aerosol-based or radar-based. Such instrumentation questions have become increasingly important in science and technology sections.
Why this question?
Tests instrument-function mapping through close distractors.
Why important for UPSC?
Increasing emphasis on indigenous scientific systems.
