Project Manager: Wendy Pennington
Instrument Provider: Ball Aerospace Technologies Corporation
Science Team and International Science Advisory NCAR, Harvard, St. Louis U., UC Berkley, U Alabama, GSFC, NOAA, EPA, Carr Astro, Dalhousie U.; GEO Instruments GEMS, Sentinel-4 & PHEMOS
Science Objectives:
Project Overview:
Selected Earth Venture Instrument-1 Nov/2012
• NASA Cost Capped & Schedule constrained to Sept. 2017 delivery
• Targeted for hosting on GEO satellite nadir deck mounted for viewing Greater North America (GNA) (Tar-sands, Canada-Yucatan P. Mexico)
• Responds to the NRC Decadal Study element of GEO-CAPE
• Spectroscopic measurements in the UV/Vis wavelengths provide a measurement suite of key elements of tropospheric air pollution chemistry.
• Measurements built on 5 heritage spectrometers flown in LEO, and SAO operational algorithms
TEMPOTropospheric Emissions: Monitoring of Pollution
• Serve as the North American geostationary component of an international constellation for air quality monitoring
• Collect simultaneous high temporal and spatial resolution measurements of pollutants over GNA
• Measure the major components, directly or by proxy, of the diurnal tropospheric O3 chemistry cycle and the cloud fields needed for data processing.
• TEMPO spectroscopic measurements will provide the measurement suite of Ozone (O3), Nitrogen dioxide (NO2),
• Formaldehyde (H2CO)• Determine the diurnal instantaneous radiative forcings
associated with pollutants and other climate agents on the continental scale.

March 10, 2015 Completed
Key Decision Point -C April 10, 2015 Confirmed
Where’s the PI?
Celebrating Phase C confirmation!
• A change, to TEMPO’s contract structure to a Firm Fixed Price Contract, was accomplished to increase the confidence in a successful instrument development under the cost cap from CPFF.
• Instrument development risks were assumed by the Prime Instrument Contractor (Ball).
• Performance Specifications:– The instrument design and interface specifications are mature
– PI/PS evaluated all science requirements to assure minimal risk
– Discipline and processes are in place that provide effective communication and review of contract deliverable products in a timely manner by the government SMEs.
• Programmatic insight and a continued collaborative environment– Continue to receive critical path report and narrative variance reports,
technical parameter metrics, technical risks and open discussions.
