Abstract :
A rapid-scan remote-sensing spectrometer based on an arbitrary waveform driven electro-optic phase modulator for spectral scans over 37 GHz and a telescope/photon counting system for detection was used to measure long term ambient level concentrations of greenhouse gases from natural targets.
