GCMD Project Keyword Description Update Request

by ASDC - gmojica » Thu Feb 05, 2026 2:45 pm America/New_York

Hello, through preparation for WebU, the ASDC is requesting the following Project Keyword Descriptions be updated in GCMD. The requested new descriptions are as follows:

Project: STAQS
New Description: NASA’s Tropospheric Emissions: Monitory of POllution (TEMPO) mission launched in early 2023 to provide geostationary observation of air quality over North America. With the addition of high-resolution satellite measurements, the Synergistic TEMPO Air Quality Science (STAQS) mission integrated TEMPO satellite observations with traditional air quality monitoring to improve understanding of air quality science and increase societal benefit. STAQS was conducted in summer 2023, targeting urban areas, including Los Angeles, New York City, and Chicago with ground and airborne measurements.

Project: STRAT
New Description: The Stratospheric Tracers of Atmospheric Transport (STRAT) campaign was a field campaign conducted by NASA from May 1995 to February 1996. The primary goal of STRAT was to collect measurements of the change of long-lived tracers and functions of altitude, latitude, and season. These measurements were taken to aid with determining rates for global-scale transport and future distributions of high-speed civil transport (HSCT) exhaust that was emitted into the lower atmosphere. STRAT had four main objectives: defining the rate of transport of trace gases from the stratosphere and troposphere (i.e., HSCT exhaust emissions), improving the understanding of dynamical coupling rates for transport of trace gases between tropical regions and higher latitudes and lower altitudes (between tropical regions, higher latitudes, and lower altitudes are where most ozone resides), improving understanding of chemistry in the upper troposphere and lower stratosphere, and finally, providing data sets for testing two-dimensional and three-dimensional models used in assessments of impacts from stratospheric aviation. To accomplish these objectives, the STRAT Science Team conducted various surface-based remote sensing and in-situ measurements. NASA flew the ER-2 aircraft along with balloons such as ozonesondes and radiosondes just below the tropopause in the Northern Hemisphere to collect data. Along with the ER-2 and balloons, NASA also utilized satellite imagery, theoretical models, and ground sites. The ER-2 collected data on HOx, NOy, CO2, ozone, water vapor, and temperature. The ER-2 also collected in-situ stratospheric measurements of N2O, CH4, CO, HCL, and NO using the Aircraft Laser Infrared Absorption Spectrometer (ALIAS). Ozonesondes and radiosondes were also deployed to collect data on CO2, NO/NOy, air temperature, pressure, and 3D wind. These balloons also took in-situ measurements of N2O, CFC-11, CH4, CO, HCL, and NO2 using the ALIAS. Ground stations were responsible for taking measurements of O3, ozone mixing ratio, pressure, and temperature. Satellites took infrared images of the atmosphere with the goal of aiding in completing STRAT objectives. Pressure and temperature models were created to help plan the mission.

Project: SUCCESS:
New Description: The Atmospheric Aerosol Chemical Composition Measurements for the Subsonic Aircraft: Contrail and Cloud Effects Special Study (SUCCESS) was an airborne expedition conducted aboard the NASA Ames DC-8 research aircraft during April/May 1996. The purpose of this project was to better determine the radiative properties of cirrus clouds and contrails so that satellite observations can more reliably assess their impact on Earth’s radiation budget. The goals of the program included determining how cirrus clouds form, whether exhaust from subsonic aircraft affects their formation, and if the changes might be climatologically significant. Measurements were taken to better determine the chemical characteristics of gaseous and particulate exhaust products from subsonic aircraft and their temporal evolution in the upper troposphere. The Global Atmospheric Chemistry Group at the University of New Hampshire conducted measurements of the detailed chemical composition of the atmospheric aerosol.

Project: TARFOX
New Description: The overall goal of the Tropospheric Aerosol Radiative Forcing Observational Experiment (TARFOX) was to reduce uncertainties in the effects of aerosols on climate by determining the direct radiative impact as well as the chemical, physical, and optical properties, of the aerosols carried over the western Atlantic Ocean from the United States. The objectives of TARFOX were to perform a variety of closure studies by using overdetermined data sets to test the mutual consistency of measurements and calculations of a wide range of aerosol properties and effects, and to use the results of the closure studies to assess and reduce uncertainties in estimates of aerosol radiative forcing, as well as to guide future field programs on this subject.

Project: THORPEX
New Description: THe Observing-system Research and predictability experiment (THORpex) was a ten-year international research program where the primary objective was to accelerate improvements in short range weather predictions and warnings over the Northern Hemisphere. THORpex is the primary over-water validation experiment for the Geosynchronous Imaging Fourier Transform Spectrometer (GIFTS) satellite.

Project: TOLNet
New Description: Ozone lidars measure continuous, high resolution ozone profiles critical for process studies and for satellite validation in the lower troposphere. However, the effectiveness of lidar validation by using single-station data is limited. Recently, NASA initiated an interagency ozone lidar observation network under the name TOLNet (Tropospheric Ozone Lidar Network) to promote cooperative multiple-station ozone lidar observations to provide highly time resolved (few minutes) tropospheric ozone vertical profiles useful for air quality studies, model evaluation, and satellite validation.

Project: TRACER-AQ
New Description: The TRacking Aerosol Convection ExpeRiment – Air Quality (TRACER-AQ) campaign was a field study co-sponsored by NASA and the Texas Commission on Environmental Quality), with partner from the Department of Energy (DOE), TRacking Aerosol Convection ExpeRiment (TRACER), and several academic institutions. This synergistic effort aimed to gain an updated understanding in photochemistry and meterological impact on ozone formation in the Houston region, particularly around the Houston Ship Channel, Galveston Bay, and the Gulf of Mexico; and provide observations for evaluating air quality models and satellite observations.

Thank you so much for your help! This should be the last batch of keyword updates I need for now. If you have any questions please let me know.
