The primary instrument is a Fourier transform spectrometer (FTS) covering the infrared from 750-4400 cm$^{-1}$ simultaneously with a maximum optical path difference of 25 cm (0.02 cm$^{-1}$ resolution). We describe free tropospheric measurements of biomass burning products such as HCN, CO, C$_2$H$_6$, CH$_3$Cl, HCOOH and 1.02 $\mu$m extinction and their interpretation based on other satellite measurements and back trajectory calculations
