THE UNIVERSITY OF MISSOURI-COLUMBIA AND SURROUNDING AREA WILL BE IN TOTALITY FOR APPROXIMATELY 2 MINUTES AND 40 SECONDS DURING THE 2017 SOLAR ECLIPSE AND POSSESSES CONSIDERABLE HUMAN AND INSTRUMENTAL RESOURCES FOR THE OBSERVATION AND ANALYSIS OF GEOPHYSICAL DATA FROM THIS EVENT. THE PRINCIPAL SCIENTIFIC GOAL OF THIS PROPOSED RESEARCH IS TO EXAMINE THE MULTI-SCALE LAND-ATMOSPHERE RESPONSES TO THE VARIATIONS IN SOLAR FORCING DURING THE ECLIPSE USING EARTH SCIENCE ASSETS. SPECIFIC OBJECTIVES ARE TO: (1) EXAMINE FIELD-SCALE CHANGES IN LAND-ATMOSPHERE CARBON DIOXIDE ENERGY AND RADIATION EXCHANGES TURBULENCE STRUCTURE AND CANOPY CONDUCTANCE CAUSED BY VARIATIONS IN SOLAR FORCING AND DETERMINE WHETHER THERE ARE DIFFERENCES IN RESPONSES FOR FOREST PRAIRIE AND CROPLAND ECOSYSTEMS; AND (2) EXAMINE THE LARGER SCALE THERMALLY INDUCED CHANGES IN THE WIND FIELDS AND THERMODYNAMIC STATE OF THE ATMOSPHERE.PURCHASE REQUISITION: 4200618711
