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.

FFP Instrument contract award

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.
