Airborne and Satellite Investigation of Asian Air Quality (ASIA-AQ)
The Airborne and Satellite Investigation of Asian Air Quality (ASIA-AQ) was an international cooperative investigation to study the factors contributing to local air quality across Asia. Measurements from ASIA-AQ were collected to validate aerosol satellite observations from South Korea’s Geostationary Environment Monitoring Spectrometer (GEMS), the upcoming Multi-Angle Imager for Aerosols (MAIA) mission, and other low-orbiting satellites. ASIA-AQ had one deployment from January to April 2024 across eastern Asia mainly targeting South Korea, Philippines, and Thailand.
Applied Sciences
Connecting NASA researchers with interagency activities and partnerships to facilitate practical and innovative uses of Earth observations for societal benefit in six thematic areas: Air Quality and Health, Chesapeake Bay, Climate and Environmental Health, Disasters, Food Security, and Mission Applications.
Atmospheric Pressure Sounder
The long-term goal of this activity is to demonstrate the feasibility of a laser sounder instrument capable of measuring the surface-pressure field for the entire air column from satellite-to-ground with global coverage. The earth's surface pressure is a vital component of a variety of important scientific measurements, which are being undertaken at Goddard. Accurate knowledge of the surface pressure can enable calibration of 2-D measurements of CO2 content in the atmosphere and greatly improve the fidelity of surface water redistribution measurements from time-varying gravity fields. It is also important in weather prediction and atmospheric modeling.
Aura
Aura (Latin for breeze) was launched on July 15, 2004, and obtains measurements of ozone, aerosols and key gases throughout the atmosphere using technologically innovative space instrumentation. Scientists use these data to gain revolutionary insights into the chemistry of our atmosphere.
Blueflux
BlueFlux is supported by the NASA Carbon Monitoring System to measure fluxes of carbon dioxide and methane emissions over blue carbon ecosystems. The measurements are made using chambers, flux towers and aircraft flux instruments, including the CARbon Flux Experiment (CARAFE) payload. The data products will be used by local stakeholders to support mangrove and sawgrass restoration for carbon sequestration.
Clouds and the Earth’s Radiant Energy System (CERES)
The Clouds and the Earth’s Radiant Energy System (CERES) project provides satellite-based observations of ERB and clouds. It uses measurements from CERES instruments flying on several satellites along with data from many other instruments to produce a comprehensive set of ERB data products for climate, weather and applied science research.
Dynamics and Chemistry of the Summer Stratosphere (DCOTSS)

Moderate Resolution Imaging Spectroradiometer (MODIS)
MODIS (or Moderate Resolution Imaging Spectroradiometer) is a key instrument aboard the Terra (originally known as EOS AM-1) and Aqua (originally known as EOS PM-1) satellites. Terra's orbit around the Earth is timed so that it passes from north to south across the equator in the morning, while Aqua passes south to north over the equator in the afternoon. Terra MODIS and Aqua MODIS are viewing the entire Earth's surface every 1 to 2 days, acquiring data in 36 spectral bands, or groups of wavelengths (see MODIS Technical Specifications). These data will improve our understanding of global dynamics and processes occurring on the land, in the oceans, and in the lower atmosphere. MODIS is playing a vital role in the development of validated, global, interactive Earth system models able to predict global change accurately enough to assist policy makers in making sound decisions concerning the protection of our environment.
NASA-Unified Weather Research and Forecasting (NU-WRF)
The NASA-Unified Weather Research and Forecasting (NU-WRF) model is an observation-driven regional earth system modeling and assimilation system at satellite-resolvable scale. NU-WRF is one of three major earth system modeling systems funded by NASA’s Modeling Analysis and Prediction (MAP) program.
Network for the Detection of Atmospheric Composition Change (NDACC)
The international Network for the Detection of Atmospheric Composition Change (NDACC) is composed of more than 70 globally distributed, ground-based, remote-sensing with more than 160 currently active instruments.
NOAA-21 (formerly Joint Polar Satellite System-2) (NOAA-21 (JPSS-2))
The Joint Polar Satellite System (JPSS) is the restructured civilian portion of the National Polar-orbiting Operational Environmental Satellite System (NPOESS) that will make afternoon observations as it orbits Earth. The system includes the satellites and sensors supporting civil weather and climate measurements and a shared ground infrastructure with the Department of Defense weather satellite system. JPSS-2 successfully lifted off from Vandenberg Space Force Base on Nov. 10, 2022, at 1:49 a.m. PST and was renamed NOAA-21.
Pandora Project
The Pandora Project addresses the needs of various different NASA Earth Ventures. Earth Venture Instruments (EVI) and Earth Venture Suborbitals (EVS) have made use of the Pandora instrument for the purposes of validation and verification. Missions and investigations uniquely aimed at exploring different components of the Earth system, ventures like DISCOVER-AQ have made use of the unique air quality measurement capabilities of Pandora.

Southern Hemisphere ADditional OZonesondes (SHADOZ)
SHADOZ is a NASA project to augment and archive balloon-borne ozonesonde launches and to archive data from tropical and remote operational sites. The project was initiated in 1998 by NASA's Goddard Space Flight Center, the NOAA/Global Monitoring Division, and international co-investigators. There are currently fourteen stations launching ozonesondes in the SHADOZ network. The collective data set provides the first climatology of tropical ozone in the equatorial region, enhances validation studies aimed at improving satellite remote sensing techniques for tropical ozone estimations, and serves as an educational tool to students, especially in participating countries.
Stratospheric Aerosol and Gas Experiment III - International Space Station (SAGE III - ISS)
The SAGE III instrument is used to study ozone, a gas found in the upper atmosphere that acts as Earth’s sunscreen. SAGE III - ISS will provide global, long-term measurements of key components of the Earth's atmosphere. The most important of these are the vertical distribution of aerosols and ozone from the upper troposphere through the stratosphere. In addition, SAGE III also provides unique measurements of temperature in the stratosphere and mesosphere and profiles of trace gases such as water vapor and nitrogen dioxide that play significant roles in atmospheric radiative and chemical processes.
Student Airborne Research Program (SARP)
The Student Airborne Research Program (SARP) is an eight-week summer internship program for rising senior undergraduate students to acquire hands-on research experience in all aspects of a scientific campaign using one or more NASA Airborne Science Program flying science laboratories (aircraft used for SARP have included the DC-8, P-3B, C-23, UC-12B, and ER-2).
