Abstract
The MOPITT Airborne Test Radiometer (MATR) uses gas filter correlation radiometry to measure tropospheric carbon monoxide (CO) with three optical channels or methane (CH4) with one channel. MATR uses the same gas correlation techniques as does the MOPITT satellite instrument, namely length modulation and pressure modulation. MATR data serves to test retrieval techniques for converting infrared radiometric data into atmospheric CO, or CH4, amounts. MATR will also be applied to MOPITT data validation. This paper gives an overview of the MATR instrument design; it discusses the results of laboratory testing and calibration; and it presents results from recent flights.
