Fabry-Perot Based Differential Radiometers for Precise Determination of Atmospheric ColumnWe have developed at Goddard over the last 5 years a new type of remote sensing instrument based upon the Fabry-Perot interferometer that has broad applicability to a variety of problems of great current interest. The instrument detects absorption features of various atmospheric trace species in direct or reflected sunlight. The Fabry-Perot offers high resolution and high optical throughput with small size and simplicity of operation. We have developed instruments for use as ground based, airborne and satellite sensors for species such as carbon dioxide, oxygen and water vapor. Our current concentration is to develop an ultra precise, inexpensive, ground based device suitable for wide deployment as a validation instrument for the OCO satellite scheduled to launch in 2008. We shall show sensitivity measurements for these three species, compare our water vapor measurements to those obtained using other types of sensors and discuss some of the peculiarities that must be addressed in order to provide the very high quality column measurements required to validate the OCO carbon dioxide measurements.
