The Korea-United States Ocean Color Study (KORUS-OC) was a collaborative effort between NASA and the Korea Institute of Ocean Science and Technology (KIOST) to examine phytoplankton and its impact on atmospheric and oceanic processes. KORUS-OC included one deployment during the boreal spring of 2016 in waters surrounding South Korea. Two research vessels were used to gather data on phytoplankton, atmospheric conditions, and other ocean parameters. NASA’s B-200 aircraft was also equipped with the Geostationary Trace Gas and Aerosol Sensor Optimization (GeoTASO) and Multi-slit Optimized Spectrometer (MOS) to capture remote sensing data over the ships. KORUS-OC was funded by NASA's Ocean Biology and Biogeochemistry program and served as the sister campaign to KORUS-AQ.
The Geostationary Trace gas and Aerosol Sensor Optimization (GeoTASO) is an airborne pushbroom spectrometer built by Ball Aerospace with support from NASA’s Earth Science Technology Office. GeoTASO measures nadir backscattered solar radiation in the ultraviolet (290-400 nm) and visible (415-695 nm) wavelengths. These measurements can be used to determine aerosols and trace gases in the atmosphere, such as ozone, formaldehyde, and nitrogen dioxide. GeoTASO has a spatial resolution of approximately 250 m by 250 m and an integration time of 0.25 seconds.
The Spectral Aerosol Extinction (SpEx) is a ground-based in situ spectrometer that measures ambient aerosol extinction. It is a modified aerosol extinction differential optical absorption spectrometer (AE-DOAS) with faster data acquisition and increased sensitivity. It measures aerosol extinction in the 300 to 700 nm wavelength range at a spectral resolution of about 0.7 nm. SpEx provides intensity spectra every 125 seconds and aerosol extinction every 250 seconds.
Ceilometers are ground-based remote sensing sensors that measure cloud ceilings and vertical visibility. They utilize a laser or another light source to detect backscatter from clouds, precipitation, and aerosols. Ceilometers provide detailed and precise measurements under all weather conditions and are cost-effective to operate. They are commonly used in boundary layer and cloud research.
The Cloud Aerosol and Precipitation Spectrometer (CAPS) is an in situ airborne spectrometer manufactured by Droplet Measurement Technologies. It combines the Cloud Imaging Probe (CIP), the Cloud and Aerosol Spectrometer (CAS), and the Hotwire Liquid Water Content (LWC) Sensor into a single instrument. CAPS measures the size distribution of aerosol, cloud, and liquid droplets for particles between 50-1600 μm in size, with a time resolution of 1 Hz. It can also capture images of cloud particles and provide measurements of temperature, pressure, and LWC.
Generic-Chemistry Related Sensors (Gen-Chemistry) refers to non-specific instruments on a platform used for atmospheric chemistry measurements. These are typically in situ analyzers that measure various chemical compounds such as trace gases, halocarbons, volatile organic compounds, nitrates, aerosols, and other chemical species. Measurements can include mixing ratio, composition, particle size, optical properties, and particle size distribution.
Nephelometers are in situ optical sensors that can be airborne or ground-based. They measure the total scattering and backscattering of aerosol particles in the atmosphere. Nephelometers operate at three wavelengths: 450 nm, 550 nm, and 700 nm, with a typical time resolution of 1 Hz.
Spectrophotometers are passive photometers that measure the light intensity of the sample solution as a function of the wavelength of the electromagnetic radiation. Spectrophotometers are typically used for ground-based or shipborne observations. They can operate either in the ultraviolet to visible (185-700 nm) spectral range or the infrared (700-15000 nm) range. They are typically used in vegetation studies, air pollution monitoring, and water and soil quality analysis.
Thermo Scientific Gas Analyzers are in situ gas analyzers manufactured by ThermoFisher Scientific. They provide precise measurements of various trace gases such as ozone, carbon dioxide, carbon monoxide, and sulfur dioxide. Thermo Scientific Gas Analyzers can be deployed on aircraft, research vessels, and ground-based platforms.
The Pandora Spectrometer System is a ground-based UV-VIS spectrometer designed to measure column amounts of trace gases in the atmosphere. It employs total optical absorption spectroscopy for retrievals of ozone, nitrogen dioxide, formaldehyde, and other trace gases. Pandora operates within the 280-525 nm spectral range at a resolution of 0.6 nm. It can perform both direct sun and all-sky radiance measurements, with an overall measurement time of 80 seconds. Pandora is part of a network of identical instruments called the Pandonia Global Network.
Generic-Atmospheric State (Gen-AtmsState) refers to non-specific instruments on a platform used for measurements of atmospheric state parameters. These are typically in situ sensors that measure temperature, pressure, humidity, and wind speed/direction. Types of atmospheric state instruments include thermometers, hygrometers, barometers, and anemometers.

NOx/NOxy is an in situ chemiluminescence instrument that measures nitrogen oxides and ozone in the atmosphere. It offers a spatial resolution better than 100 meters at typical DC-8 research flight speeds. NOx/NOxy can be used on ground-based, airborne, and shipborne platforms, enabling it to support various atmospheric chemistry and air quality studies.
