Geostationary satellite retrievals of aerosol optical thickness during ACE-Asia

[1] Using 30 days of hourly geostationary satellite (GMS5 imager) data and discrete ordinate radiative transfer (DISORT) calculations, aerosol optical thickness (AOT) at 0.67 mm was retrieved over the west Pacific Ocean (20 N–45 N, 110 E–150 E) during the Aerosol Characterization Experiment (ACE-Asia) intensive observation period in April 2001. Different from previous one-channel retrieval algo...

Wind Estimation from Geostationary-satellite Pictures

The motion of properly selected clouds derived from photographs taken by the geostationary Advanced Technology Satellites provides estimates of the wind a t cloud level. A large number of lowand high-cloud motions near rawin stations are compared to the balloon-derived winds to determine the levels at which these wind estimates might be used for map analyses and to assess their accuracy a t tho...

Near quantum-limited, single-shot coherent arbitrary optical waveform measurements.

Four-quadrature spectral interferometry using balanced coherent detection enables single-shot full-field characterization of complex-shaped optical waveforms with near quantum-limited sensitivity. A 90 degrees optical hybrid places a waveform in four-quadrature-phases with a stronger, well-characterized reference pulse. Measurement of the four spectra with an integrating two-dimensional detecto...
