Lidar Remote Sensing of Sound Velocity in the Ocean
نویسنده
چکیده
Our goal is the rapid and accurate measurement of upper-ocean vertical sound velocity (and hence temperature) profiles in the ocean. The objective is to obtain range resolved (»1 m) measurements of temperature and sound velocity over a range of »100 m at an accuracy of 0.1°C and 0.2 m/s, respectively. To this end we are developing an innovative Brillouin LIDAR concept. Present results provide considerable confidence in the success of this objective.

Recent studies showed that remote sensing (RS) is an effective, efficient and reliable technique used in almost all the areas of earth sciences. Remote sensing as being a technique started with aerial photographs and then developed employing the multi-spectral satellite images. Nowadays, it benefits from hyper-spectral, RADAR and LIDAR data as well. This potential has widen its applicability in...
متن کاملAerosol Retrievals from CALIPSO Lidar Ocean Surface Returns
This paper describes approaches to retrieve important aerosol results from the strong lidar return signals that are received by the space-borne CALIPSO lidar system after reflecting off-ocean surfaces. Relations, from which the theoretically expected values of area under ocean surface returns can be computed, are presented. A detailed description of the lidar system response to the ocean surfac...

We present a comprehensive database of near-shore wind observations that were carried out during the experimental campaign of the RUNE project. RUNE aims at reducing the uncertainty of the near-shore wind resource estimates from model outputs by using lidar, ocean, and satellite observations. Here we concentrate in describing the lidar measurements. The campaign was conducted from November 2015...

1. To demonstrate theoretically emergence of the deterministic Green’s functions (GFs) from noise sources distributed in a volume and on boundaries in inhomogeneous, fluid-solid environments with dissipation. 2. To investigate a relation between the deterministic GFs and a two-point correlation function of noise in a low-frequency regime where stationary-point arguments become inapplicable. 3. ...
