NASA | On Board NPP: Ozone Mapper Profiler Suite

The video discusses the importance of measuring the stratospheric ozone layer, which protects Earth from harmful ultraviolet radiation. It highlights the role of chlorofluorocarbons (CFCs) in ozone depletion and the impact of the Montreal Protocol in reducing these substances. The OHMSS instrument on NASA's NPP satellite is introduced as a key tool for collecting long-term ozone data. The video explains how this data helps in understanding ozone distribution and changes over time. It also covers the process of data transmission from the satellite to ground stations and its use in computing UV indices and monitoring ozone layer recovery.

What is the primary function of the ozone layer in the stratosphere?

• To absorb carbon dioxide

• To block ultraviolet radiation

• To increase global temperatures

• To produce oxygen

Which human-made substances are primarily responsible for ozone depletion?

• Carbon monoxide

• Nitrous oxide

• Chlorofluorocarbons (CFCs)

• Methane

What is the role of the OHMSS instrument on NASA's NPP satellite?

• To measure sea levels

• To monitor ozone levels

• To track weather patterns

• To study solar flares

How does the OMPS instrument improve upon older mapping instruments?

• By measuring only surface ozone levels

• By providing a vertical distribution profile of ozone

• By mapping only the ozone at the equator

• By focusing on oceanic ozone levels

What is one of the long-term goals of analyzing data from the NPP satellite?

• To measure global warming rates

• To track deforestation

• To determine if the ozone layer is recovering

• To predict volcanic eruptions
