Abstract

Carbon dioxide, water vapour, air temperature and wind measurements at 10 Hz sampling rate were carried out over the coast of Arabian Sea, Goa (15°21'N, 73°51'E) in India. These observations were collected, in association with the surface layer turbulent parameters for the Arabian Sea Monsoon Experiment (ARMEX). In the summer monsoon period, concentration of CO 2 was in the range of 550-790 mg m -3 whereas the water vapour was in the range of 17.5-24.5 g m -3. The Fast Fourier Transform (FFT) analysis has been performed on these observations to investigate the spectral behaviour of CO 2 and water vapour. The relation between CO 2 and water vapour on various atmospheric scales has been proposed. CO 2 and water vapour observations confirmed the existence of periodicities of large (11, 8 days), meso (5 days) and micrometeorological (20 min) scales.
