TEMPO Space-Based Pollution Monitoring Instrument Passes NASA Review

TEMPO Pollution Monitoring Instrument Passes Critical Review

Scheduled for completion in 2017, TEMPO is a pollution monitoring instrument that will ride aboard a commercial satellite that’s to be launched no later than 2021.

A new space-based instrument that will monitor major air pollutants across North America on an hourly basis has successfully completed a critical review by NASA.

Cambridge, Massachusetts – The Tropospheric Emissions: Monitoring of Pollution (TEMPO) instrument passed a major milestone April 10, 2015 by successfully completing a critical NASA confirmation review. It has been confirmed by NASA’s Science Mission Directorate to continue into the Phase C part of the project, in which the team completes the design that meets the science and measurement requirements, fabricates the instrument, and develops the ground system. TEMPO will measure North American air pollution hourly from geostationary orbit.

TEMPO will be completed in 2017 at a cost of no more than $93.2 million, excluding the launch vehicle and integration to the selected satellite platform. It will share a ride on a commercial satellite as a hosted payload.

Once deployed, TEMPO will acquire spectra of the Earth’s atmosphere in ultraviolet and visible wavelengths. These will provide measurements of key pollution concentrations in the Earth’s lower atmosphere, the troposphere. Measurements include ozone, nitrogen dioxide, formaldehyde, sulfur dioxide, and aerosols.

TEMPO was competitively selected as the first NASA Earth Venture Instrument. Earth Venture missions, part of the Earth System Science Pathfinder program, are small, targeted science investigations that complement NASA’s larger research missions. TEMPO is led by Principal Investigator Kelly Chance and Deputy Principal Investigator Xiong Liu, both at the Smithsonian Astrophysical Observatory in Cambridge, MA. The Instrument Project Manager, Wendy Pennington, and the Project Scientist, David Flittner, are at NASA Langley Research Center in Hampton, VA.

“The team is looking forward to continuing to the next phase of the project to build the TEMPO instrument that will serve as the North American geostationary component for air-quality monitoring,” said Pennington.

According to Chance, “TEMPO exploits thirty years of our development of ultraviolet and visible atmospheric spectroscopy to make air quality measurements at revolutionary spectral and spatial scales.”

The TEMPO instrument is being built by Ball Aerospace & Technologies Corporation under Project Manager Dennis Nicks. In addition to the Smithsonian Astrophysical Observatory and NASA Langley Research Center, TEMPO includes NASA Goddard Space Flight Center, the Environmental Protection Agency, the National Oceanic and Atmospheric Administration, Carr Astronautics, RT Solutions, and a number of U.S. universities. It also has strong Canadian and Mexican involvement in the Science Team.

Headquartered in Cambridge, Massachusetts, the Harvard-Smithsonian Center for Astrophysics (CfA) is a joint collaboration between the Smithsonian Astrophysical Observatory and the Harvard College Observatory. CfA scientists, organized into six research divisions, study the origin, evolution and ultimate fate of the universe.
