For measuring ozone concentration in the Antarctic stratosphere, a polar orbit is ideal as it allows satellites to pass over the poles regularly, ensuring comprehensive coverage of the region. While all orbits are technically elliptical, specific types like sun-synchronous orbits can provide consistent lighting conditions for observations. The discussion emphasizes the importance of selecting an orbit that maximizes data collection over the targeted area. Resources are shared to help understand the implications of different orbital paths. Understanding the relationship between satellite orbits and their observational capabilities is crucial for effective scientific measurements.
