Under which mission has the AATAL air pollution analysis laboratory for Delhi NCR been established?

  1. A.Mission LiFE
  2. B.National Clean Air Programme
  3. C.Mission Mausam
  4. D.Mission Vayu Shakti

Correct answer

C. Mission Mausam

Explanation

The correct answer is Mission Mausam. The laboratory has been established under Mission Mausam, announced by Prime Minister Narendra Modi, to deepen the scientific understanding of atmospheric pollution and to supply usable evidence for managing air quality in Delhi NCR. It is implemented through the Ministry of Earth Sciences, and the inauguration was held at the Delhi branch of the Indian Institute of Tropical Meteorology in the presence of the Secretary of the ministry, Dr T. Srinivasa Kumar, IITM Director Dr A. Suryachandra Rao and the Director General of the India Meteorological Department. Option A is wrong because the mission named for the facility is Mission Mausam and not any lifestyle-related mission. Option B is wrong for the same reason: the laboratory will serve pollution-control authorities with evidence, but the release attributes its creation to Mission Mausam. Option D is wrong because no such mission is named in connection with the laboratory. Also worth remembering is that the facility is integrated with the AIRWISE decision support system of the same institute.

Q1.Science & TechnologyEasy

What does AATAL, the new facility set up for Delhi NCR, stand for?

  1. A.Advanced Aerosol Tracking and Atmospheric Laboratory
  2. B.Integrated Atmospheric Chemistry and Aerosol Toxicity Analysis Laboratory
  3. C.All India Air Toxicity Assessment Laboratory
  4. D.Atmospheric Analysis and Thermal Aerosol Laboratory
Show answer
Correct answer: B. Integrated Atmospheric Chemistry and Aerosol Toxicity Analysis Laboratory

That is the full form of AATAL, the facility inaugurated for Delhi NCR by Dr Jitendra Singh at the Delhi branch of the Indian Institute of Tropical Meteorology.

Q2.Science & TechnologyMedium

At what spatial resolution, and for how long ahead, does the AIRWISE system linked with AATAL forecast air quality?

  1. A.400 metres, for the next 72 hours
  2. B.1 kilometre, for the next 48 hours
  3. C.100 metres, for the next 24 hours
  4. D.4 kilometres, for the next 96 hours
Show answer
Correct answer: A. 400 metres, for the next 72 hours

AIRWISE, the Air Quality Warning and Integrated Decision Support System for Emissions, issues air-quality forecasts at a spatial resolution of 400 metres for the following 72 hours.

Q3.Science & TechnologyEasy

Which share of Delhi's air pollution was shown as coming from transport on the screen at the inauguration of AATAL?

  1. A.About 10 per cent
  2. B.About 25 per cent
  3. C.About 45 per cent
  4. D.About 60 per cent
Show answer
Correct answer: B. About 25 per cent

Explaining what real-time source apportionment means, Dr Jitendra Singh pointed to a screen showing that at that moment transport was contributing roughly 25 per cent of the air pollution in Delhi, while the overall pollution level stood at around 180.

Q4.Science & TechnologyHard

According to the ARIES study, what happens to the shock in the accretion disc when a black hole spins rapidly?

  1. A.It is pushed farther from the black hole, giving only low-frequency QPOs
  2. B.It is pulled closer to the black hole, producing QPOs over a wider range of frequencies
  3. C.It disappears completely and no QPOs are produced
  4. D.It becomes permanently stable and stops oscillating
Show answer
Correct answer: B. It is pulled closer to the black hole, producing QPOs over a wider range of frequencies

The simulations showed that as spin increases, the oscillating shock moves inward and its oscillations grow more pronounced, so the predicted frequencies can exceed 100 Hz for a black hole of about ten solar masses, which matches the fast variations observed in black hole X-ray binary systems.

Q5.Science & TechnologyEasy

In the context of black hole research, QPO stands for:

  1. A.Quantum Photon Oscillation
  2. B.Quasi-Periodic Oscillation
  3. C.Quadrupole Phase Orbit
  4. D.Quasar Polar Outflow
Show answer
Correct answer: B. Quasi-Periodic Oscillation

Matter pulled towards a black hole forms an accretion flow that falls inward at high speed and emits non-thermal radiation, and the brightness of that radiation shows nearly regular variations known as quasi-periodic oscillations.
