Correct answer: C. 100 DU
Explanation
One Dobson Unit is defined as a 0.01 mm thick layer of pure ozone at standard temperature and pressure. A 1 mm layer therefore equals 1 ÷ 0.01 = 100 DU. (For reference, the average global ozone column is about 300 DU, i.e. a 3 mm layer.)एक डॉब्सन इकाई की परिभाषा मानक ताप और दाब पर शुद्ध ओज़ोन की 0.01 mm मोटी परत के रूप में की जाती है। अतः 1 mm की परत = 1 ÷ 0.01 = 100 DU। (संदर्भ हेतु, वैश्विक औसत ओज़ोन स्तंभ लगभग 300 DU अर्थात् 3 mm परत के तुल्य होता है।)More People, Development and Environment questions
