Abstract

Carbon sink and urban CO2 dome mapping in tropical environment, by means of hiperspectral remote sensing The aim of this paper is present the CO2 flux mapping using model proposed by Rahman et al. (2000) to Cerrado tropical environment. It was used two AVIRIS scenes and one Hyperion scene. Besides it was developed a new spectral index, ICO2, for mapping the carbon dioxide contents in atmosphere, using the 2.0 mm spectral feature, and correlated with the CO2 flux model. The results describe, in all cases, a negative function and present a high correlation coefficient. Another aspect presented in this paper is a new methodology to map urban CO2 dome phenomenon using hiperspectral data and the ICO2. Keywords: spectral index; CO2 flux; AVIRIS, Hyperion; urban CO2 dome
