"" other functions: tropospheric emissions: monitoring of pollution (tempo) support 3.1. The purpose of this task is to obtain support for the tempo independent reviews and associated activities. 3.2. The objective of this task is to support a standing review board (SRB) that is responsible for independently assessing the health of the project. Independent reviews of projects are conducted at defined lifecycle milestones and are used to objectively assess the project s progress against the project plan, its readiness to proceed to the next lifecycle phase, compliance with NPR 7120.5 and NPR 7123.1 requirements, and the integrated baseline. 3.3. The (tropospheric emissions: monitoring of pollution) tempo mission includes the tempo instrument project and the tempo mission project. The tempo instrument project consists of the tempo instrument; ground systems; instrument operations; and science data processing. The tempo mission project consist of mission systems engineering and procuring a ride on a commercial geostationary earth orbit (GEO) host that will include the spacecraft, instrument integration, launch vehicle, data downlink, and the ground system to transfer the data to the tempo instrument operations center. The tempo instrument is an earth venture instrument announcement of opportunity (AO) selected instrument within the earth system science pathfinder (essp) program, with ultimate project authority under principal investigator kelly chance of the smithsonian astrophysical observatory (SAO). The essp program office (essp PO) is located at the NASA langley research center (larc) and is responsible for overall program management. The essp program reports to the earth science division (ESD) within the NASA science mission directorate (SMD) at NASA headquarters. The tempo mission project is a directed project at larc charged with procuring the host mission ride. The tempo instrument is classified as category 3 (NPR 7120.5E), class c (NPR 8705.4) with the SMD associate administrator (AA) designated as the decision authority. The PI has delegated the authority for project management, system engineering, and safety and mission assurance, to larc. Tempo will measure atmospheric pollution covering most of north america, from mexico city to the canadian TAR/oil sands, and from the atlantic to the pacific hourly and at high spatial resolution. Tempo s measurements from geostationary orbit (GEO) of tropospheric ozone, ozone precursors, aerosols, and clouds will create a revolutionary dataset that provides understanding and improves prediction of air quality (AQ) and climate forcing.
