Visible and Infrared Imaging Spectrometer (AVIRIS) and the MODIS/ASTER Airborne Simulator (MASTER). These two sensors were flown over Southern California on a NASA ER-2 aircraft as part of the Hyperspectral Infrared Imager (HyspIRI) mission preparatory flight campaign on 24 September 2013. The AVIRIS is an optical sensor that delivers calibrated images of the upwelling spectral radiance in 224 contiguous spectral bands with wavelengths from 400 to 2500 nm, covering the visible and near-infrared

radiation, diffuse radiation, and photosynthetically active radiation), air temperature, and relative humidity. Picarro Cavity Ring-Down Spectrometer (CRDS, model G2302) analyzers are employed at four of the sites for CO 2 and CO mixing ratios ( Crosson 2008 ) and the Mature Pine site (OMT) is equipped with a closed-path infrared gas analyzer (IRGA, model LI840). To align all observation data with WMO standard references, measured mixing ratios are linearly corrected using CO and CO 2 calibration
