Chemistry & Climate Processes: Projects

Members of the Chemistry & Climate Processes group have been involved in flight planning for a variety of aircraft-based observational missions. Examination of the meteorological conditions in and around the field mission investigative area provides information to the flight and mission directors that is critical in determining which flight paths and altitudes are best suited for measuring the chemical species of interest.


NASA DC-8
NASA DC-8 research aircraft

ATom, NASA Armstrong. The Atmospheric Tomography Mission (ATom) will study the impact of human-produced air pollution on certain greenhouse gases in the global atmosphere. Airborne instruments will look at how atmospheric chemistry is transformed by various air pollutants and at the impact on methane and ozone which affect climate. Flights aboard NASA's DC-8 will originate from the Armstrong Flight Research Center in Palmdale, California, fly north to the western Arctic, south to the South Pacific, east to the Atlantic, north to Greenland, and return to California across central North America.

fiber optic temperature profiler launch
EOSS 204 fiber-optic temperature profiler launch 7 March 2015

Balloon Borne Fiber Optic Temperature Profiler Sensor project. This project seeks to demonstrate the capabilities of a fiber-optic temperature profiler instrument for use aboard a drifting high altitude balloon platform, with the ultimate goal of enabling high vertical resolution temperature measurements within the Tropical Tropopause Layer. These measurements will make a significant contribution to our understanding of stratospheric dynamics and composition, which are both important for understanding climate variability and climate change. Testing this new instrument has been funded by a CIRES Innovative Research Program grant, and is joint with CU-LASP and Edge of Space Sciences (EOSS); a Denver, Colorado based non-profit organization that promotes science and education by exploring frontiers in amateur radio and high altitude balloons. The goal is to eventually fly this instrument on the Strateole-2 Campaign on Science of the Equatorial Upper Troposphere/Lower Stratosphere during 2017/2018. More info...

Grounded ice bergs near Antarctica field site

2ODIAC, Antarctica. The 2-season Ozone Depletion and Interaction with Aerosols Campaign (2ODIAC) is the first simultaneous high-resolution measurements of the physics and chemistry of aerosols (fine particles in the atmosphere) and trace gasses (such as ozone) in Antarctica. 2ODIAC will provide the most detailed observations of naturally occurring aerosols and trace gases ever made in Antarctica. By using state of the art instrumentation for the first time in Antarctica, we will be able to answer questions about the composition, sizes and chemistry of these fine particles, the natural and man made sources of these particles, their interactions with gases, snow, and ice, and how they evolve between the dark, sunless winters and the perpetual daylight of summer. These data will be fundamental to understanding the role of aerosol particles in the pristine environment of Antarctica. Scientists involved are from the University of Colorado (LASP and CIRES), Drexel University, and the University of Wyoming. More info...


NOAA Manta UAS launch
NOAA Manta Unmanned Aircraft System (UAS) launch

NOAA SEED project. The NOAA Special Early-Stage Experimental or Developmental (SEED) project conducted the very first test flights for new instruments designed to measure properties and climate effects of airborne fine particles (aerosols) using the Manta Unmanned Aircraft System (UAS). CSD developed two new instruments for the Manta, the Printed Optical Particle Spectrometer (POPS) and an upward-looking radiometer (ULR), filling key measurement gaps in the payload. They contribute to a potentially powerful new tool for NOAA to address climate and air quality issues related to aerosols in remote and hard-to-access regions. More info...


SEAC4RS logo

SEAC4RS, Houston, Texas. Studies of Emissions and Atmospheric Composition, Clouds and Climate Coupling by Regional Surveys (SEAC4RS) is based out of Ellington Field in August - September 2013. Focused on pollution emissions and the evolution of gases and aerosols in deep convective outflow, and the influences and feedbacks of aerosol particles from anthropogenic pollution and biomass burning on meteorology and climate, the project requires two aircraft to accomplish the goals. The NASA DC-8 will provide observations from near the surface to 12 km, and the NASA ER-2 will provide high altitude observations reaching into the lower stratosphere as well as important remote sensing observations connecting satellites with observations from lower flying aircraft and surface sites.

ATTREX logo

ATTREX, NASA Armstrong (formerly Dryden) and Guam. Airborne Tropical Tropopause Experiment (ATTREX) will perform a series of measurement campaigns (September - November 2011, November 2012 - February 2013, January - March 2014) using the high-altitude long-range NASA Global Hawk (GH) unmanned aerial system (UAS) to evaluate changes in stratospheric humidity and ozone concentration.

HIPPO logo

HIPPO IV & V, Pacific Basin. The HIAPER Pole-to-Pole Observations (HIPPO) of Carbon Cycle and Greenhouse Gases Study will measure cross sections of atmospheric concentrations approximately pole-to-pole, from the surface to the tropopause, five times during different seasons over a three year period. The main goal of HIPPO is to determine the global distribution of carbon dioxide and other trace atmospheric gases by sampling at various altitudes and latitudes in the Pacific Basin. More info...


MACPEX logo

MACPEX, Houston, Texas. The Mid-latitude Airborne Cirrus Properties Experiment (MACPEX) is an airborne field campaign to investigate cirrus cloud properties and the processes that affect their impact on radiation. The campaign involves the NASA WB-57 based at Ellington Field, TX in the March / April 2011 timeframe. Science flights will focus on central North America vicinity with an emphasis over the DoE ARM SGP site in Oklahoma. More info...


GloPac logo

GloPac, NASA Dryden. Proposed flights of the Global Hawk for the Global Hawk Pacific Mission (GloPac) were conducted in support of the Aura Validation Experiment (AVE). This mission takes place out of Dryden Flight Research Center in 2010, expected to encompass the entire offshore Pacific region with four to five 30 hour flights. Aura is one of the A-train satellites supported by NASA Earth Observation System. More info...

ARCPAC, Fairbanks, Alaska. As part of the International Polar Year of 2008, NOAA engaged in an airborne field measurement campaign targeted at improving understanding climate-relevant processes. The Aerosol, Radiation, and Cloud Processes affecting Arctic Climate (ARCPAC) effort was focused on direct measurements of properties and processes that can be used to reduce uncertainty in radiation and climate models. The measurements were made in the Alaskan Arctic to closely coordinate with remote-sensing and in situ observations from aircraft and ground sites in the vicinity of Barrow, Alaska. Field support operations in collaboration with NASA's Arctic Research of the Composition of the Troposphere from Aircraft and Satellites (ARCTAS) based out of Fairbanks, Alaska. More info...
