THE PLANKTON, AEROSOL, CLOUD, OCEAN ECOSYSTEM (PACE) MISSION IS A STRATEGIC CLIMATE CONTINUITY MISSION THAT WAS DEFINED IN THE 2010 DOCUMENT RESPONDING TO THE CHALLENGE OF CLIMATE AND ENVIRONMENTAL CHANGE: NASAS PLAN FOR CLIMATE CENTRIC ARCHITECTURE FOR EARTH OBSERVATIONS AND APPLICATIONS FROM SPACE (REFERRED TO AS THE CLIMATE INITIATIVE). THE CLIMATE INITIATIVE COMPLEMENTS NASAS IMPLEMENTATION OF THE NATIONAL RESEARCH COUNCILS DECADAL SURVEY OF EARTH SCIENCE AT NASA, NOAA, AND USGS, ENTITLED EARTH SCIENCE AND APPLICATIONS FROM SPACE: NATIONAL IMPERATIVES FOR THE NEXT DECADE AND BEYOND. PACE WILL EXTEND THE HIGH QUALITY OCEAN ECOLOGICAL, OCEAN BIOGEOCHEMICAL, CLOUD, AND AEROSOL PARTICLE DATA RECORDS BEGUN BY NASA IN THE 1990S, BUILDING ON THE HERITAGE OF THE SEA-VIEWING WIDE FIELD-OF-VIEW SENSOR (SEAWIFS), THE MODERATE RESOLUTION IMAGING SPECTRORADIOMETER (MODIS), THE MULTI-ANGLE IMAGING SPECTRORADIOMETER (MISR), AND THE VISIBLE INFRARED IMAGING RADIOMETER SUITE (VIIRS). THE MISSION WILL BE CAPABLE OF COLLECTING RADIOMETRIC AND POLARIMETRIC MEASUREMENTS OF THE OCEAN AND ATMOSPHERE, FROM WHICH THESE BIOLOGICAL, BIOGEOCHEMICAL, AND PHYSICAL PROPERTIES WILL BE DETERMINED. PACE DATA PRODUCTS WILL NOT ONLY ADD TO EXISTING CRITICAL CLIMATE AND EARTH SYSTEM RECORDS, BUT ALSO ANSWER NEW AND EMERGING ADVANCED SCIENCE QUESTIONS RELATED TO EARTHS CHANGING CLIMATE. THE CONTRACTOR SHALL PROVIDE THE FACILITIES, PERSONNEL, SERVICES, TOOLS, EQUIPMENT, AND MATERIALS NECESSARY TO DESIGN, ANALYZE, MANUFACTURE, TEST, AND DELIVER THE HARDWARE AND DATA IN ACCORDANCE WITH THE REQUIREMENTS OF THIS SOW AND THE DOCUMENTS REFERENCED HEREIN.
