Preliminary Parameters for an Experimental Payload for Tropospheric CO2 Measurement Using a Space-borne Lidar 6U Cubesat Platform

By M. Fabiao Dionizio, D. V. Cotton and J. Bailey

Abstract

Summary: This paper investigates the implementation of a downward looking space-borne lidar system to map the concentration of Tropospheric CO2. Lidar has been used to measure greenhouse gases and a variety of trace species, profile winds, and producing high-resolution topographical maps. Sufficiently accurate CO2 mapping can locate and quantify sources and sinks of CO2, thus helping understand the carbon cycle, to verify the emissions accounting methods that are the basis of the developing carbon market, and to provide input for future climate predictions. The proposed payload consists of an Erbium doped fibre laser in a Master Oscillator Power Amplifier (MOPA) configuration. The laser system consists of a tunable narrow-line Continuous Wave (CW) laser of low power that produces the required narrow line shape switching between on-line and off-line wavelengths. A 10 cm aperture telescope is used as both a transmitter and receiver telescope. Preliminary results show that achieving both high spatial and temporal resolution is currently not feasible using a 6U Cubesat platform, due to power and telescope constraints
