KEY TO THIS PROPOSAL ARE THE ECLIPSE DATA OBSERVED BY THE DSCOVR EPIC AND NISTAR INSTRUMENTS AT THE LAGRANGE 1 POINT AT APPROXIMATELY 10:45 LOCAL TIME 17:45 GMT ON AUGUST 21 2017 NEAR CASPER WYOMING 42.88 N 106.3 W. BASED ON A PREVIOUS ECLIPSE OBSERVATION THE ECLIPSE CIRCLE INCLUDING TOTALITY AND THE UMBRA IS ABOUT 20 IN DIAMETER OR 2000 KM. WE ARE PROPOSING TO LOCATE 3 GROUND BASED PANDORA SPECTROMETER SYSTEMS 300 NM TO 800 NM IN THE LINE OF TOTALITY STARTING NORTH OF BOISE IDAHO 42.9 N 106.3 W ONE NEAR CASPER WYOMING 42.88N 106.3W AND ONE NORTH OF KANSAS CITY MO 39.7 N 94.6 W ACCOMPANIED BY PYRANOMETERS TO MEASURE SPECTRAL RADIANCE AND THE TOTAL IRRADIANCE ASSOCIATED WITH THE ECLIPSE AS SEEN FROM ABOVE BY EPIC AND NISTAR RESPECTIVELY. WE PROPOSE TO MAKE 1 D AND 3 D RADIATIVE TRANSFER CALCULATIONS WITH THE ATMOSPHERIC STRUCTURE OBSERVED BY EPIC AND RETRIEVED BY MODIS TO MATCH THE MEASUREMENTS MADE FROM SPACE AND GROUND THUS VALIDATING THE ABILITY OF THE RADIATIVE TRANSFER MODELS TO CAPTURE THIS SPECIAL EVENT. THE COMBINED SPATIALLY RESOLVED EPIC DATA GROUND-BASED MEASUREMENTS AND THE VALIDATED RADIATIVE TRANSFER MODEL WILL BE USED TO INTERPRET THE ECLIPSE PERTURBATION IN THE TOTAL EARTH NISTAR IRRADIANCE DATA. THE ULTIMATE OBJECT OF THIS PROJECT IS TO EXTEND THE UTILITY OF NISTAR DATA FOR USE IN THE EARTH RADIATIVE BALANCE STUDIES.
