Two techniques for deriving low-altitude temperature profiles were evaluated in an experiment conducted from November 1996 to January 1997 at the Boulder Atmospheric Observatory (BAO). The first used a scanning, single wavelength, 5-mm (60 GHz) microwave radiometer to measure vertical temperature profiles. Two radi-ometers were operated simultaneously; one(More)
~300 MHz subbands, incorporated into the PSR/CX instrument, have provided one means of interference mitigation that is useful under moderately contaminated conditions. ETL has developed a new C-band spectrometer that observes emissions within relatively narrower bandwidths and is tunable from 5.8 to 7.5 GHz. The spectrometer is able to reduce the effects of(More)
Using an integrable Gardner equation as an example, a perturbation theory is developed for systems in which limiting-amplitude solitons exist in the form of a pair of distanced kinks. Approximate equations describing multisoliton interactions are derived and further used for modeling the evolution of an arbitrary set of solitons. The results are compared(More)
Random acoustic fields generated by uncorrelated sources in moving media contain information about the propagation environment, including sound speed and flow velocity. This information can be recovered by noise interferometry. Here interferometric techniques are applied to road traffic noise. Acoustic travel times and their nonreciprocity are retrieved(More)
Observations of tsunamis in the open ocean are critical for developing early warning systems and improving our understanding of tsunami generation and propagation. An early and reliable assessment of an imminent tsunami threat requires detection of the tsunami wave in the open ocean away from the shore [1-3]. The wave amplitude of tsunamis in the open(More)
—A consistent radiometric model of the ocean is an important part of the interpretation of passive microwave ra-diometric data. Empirical relations between measured brightness temperature and environmental parameters such as wind, surface temperature, salinity, etc., are often used for processing satellite and airborne data. There are some difficulties when(More)
