EOS PI-Led Instrument Algorithm Maintenance Team for Measurements of Pollution in the Troposphere (MOPITT) Statement of Work (SOW)

1. Introduction

1.1 Purpose

This Statement of Work (SOW) covers the required activities for the continuation of the development and refinement and maintenance of the algorithms described in the existing Algorithm Theoretical Basis Documents (ATBDs). This includes the work necessary to assure the continued successful use of current algorithms and data products, periodic updates resulting from accrued experience and refinement, improvements to computing facilities, instrumental changes, and evolving all sources external inputs. It also includes all related operational aspects, and the first order validation work associated with comparing sensor data to that from aircraft and other operational satellite and ground based systems, and any other available and reliable sources.

1.2 Background

A Memorandum of Understanding (MOU) was executed on November 1994, which describes the cooperation of the flight of the Measurements of Pollution in the Troposphere (MOPITT) instrument on the NASA Polar orbiting platform Terra. The MOU also describes a related support for an international Earth Observing System (EOS) between NASA and the Canadian Space Agency (CSA). The EOS program elements and participating scientists outlined in the MOU were solicited by an Announcement of Opportunity (AO) (OSSA-1-88, Jan. 19, 1988) and a subsequent NASA Research Announcement (NRA-95-MTPE-03) was released in 2003 to select science team leaders for the development and maintenance of algorithms for the NASA Terra Spacecraft instrument MOPITT. The successful proposal from the NRA outlined a teaming arrangement between NASA, the CSA and the National Center for Atmospheric Research/University Corporation for Atmospheric Research (NCAR/UCAR), for the development and maintenance of algorithms supporting the MOPITT instrument. The CSA was responsible for the instrument development, operation and calibration, and the U.S. team, led by NCAR/UCAR with NASA, for the algorithm development and maintenance. On October 2020, the NASA Senior Review provided programmatic direction to continue the Terra mission through FY 2025.

1.3 Period of Performance

The period of performance for the work defined in this SOW begins on the date of award and continues for two years with a 3 optional one year periods.
