Which satellite is capable of detecting nighttime lights?

Which satellite is capable of detecting nighttime lights?

• A. GOES
• B. DMSP w/ OLS sensor
• C. POES
• D. NPP- VIIRS

Answer: (B)

The DMSP (Defense Meteorological Satellite Program) with the OLS (Operational Linescan System) sensor is particularly designed for monitoring and detecting nighttime lights. This capability is a result of its sensitivity to low-light levels, which enables it to capture data on artificial lighting and urbanization across the Earth. The OLS sensor can differentiate between light emitted from cities and natural terrestrial sources, providing valuable insights into human activity at night. In contrast, the other satellites listed have different primary functions. For instance, the GOES (Geostationary Operational Environmental Satellites) primarily focuses on weather observation and atmospheric data in real-time, rather than nighttime illumination detection. POES (Polar Operational Environmental Satellites) also concentrates on environmental data and is limited in sensitive low-light detection capabilities. The NPP (National Polar-orbiting Partnership) equipped with the VIIRS (Visible Infrared Imaging Radiometer Suite) sensor has improved nighttime light detection abilities but does not specifically focus on it like DMSP's OLS. Thus, while some of the other satellites have imagery capabilities, DMSP w/ OLS sensor is specialized for accurately detecting and analyzing nighttime lights.
