RECOMMENDATIONS(TENTATIVE)

- THERE IS A PRESSING NEED FOR A AIRBORNE SPECTROMETER CLASS INSTRUMENT

FOR FUNDAMENTAL RESEARCH IN THE NEW DOMAIN (FOR REMOTE SENSING) OF HIGH

SPECTRAL AND SPATIAL RESOLUTION, ONE OR MORE AIRCRAFT SENSOR DEVELOP-

MENTS SHOULD BE INITIATED AS PART OF AN OVERALL AIRCRAFT MEASUREMENT

RESEARCH PROGRAM,

- DEVELOP AND FABRICATE PORTABLE FIELD INSTRUMENTS_ CONDUCT SUPPORTIVE

TESTS, AND PROVIDE DATA FOR RESEARCH

- CONTINUE SCIENCE STUDIES TO CONVERGE THE SENSOR DESIGN AND PROVIDE AN

IMPROVED SCIENCE BASIS AND RATIONALE FOR MLA TYPE SYSTEMS,

- DEVELOP. SPECIFIC MISSION SCENARIOS WITH FURTHER INPUTS FROM THE DISCIPLINE

PANEL AS PART OF THE FOLLOW-ON TO THE MSWIG EFFORT,

- FOSTER AN INVOLVEMENT OF A BROADER CROSS SECTION OF THE REMOTE SENSING

COMMUNITY INCLUDING UNIVERSITIES TO DEVELOP A CONSTITUENCY AND ADVOCACY

GROUP FOR THIS TECHNOLOGY,

. - CONTINUE ON-GOING ENGINEERING AND CRITICAL DEVELOPMENTS IN AREAS SUCH AS

WIDE FIELD OPTICS_ FOCAL PLANES_ AND SPECTRAL FILTER TECHNIQUES,

- DEVELOP A BETTER UNDERSTANDING OF THE TRADES AND INTERACTIONS BETWEEN THE

GROUND AND SPACE SEGMENT FOR STRAWMAN SCENARIOS,
