The Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) satellite will be launched in April of 2005, and will make continuous measurements of the Earth's atmosphere for the following three years. Retrieving the spatial and optical properties of clouds and aerosols from the CALIPSO lidar backscatter data will be confronted by a number of difficulties that are not faced i...

In the past few years, we have demonstrated how the surface return measured by the active instruments onboard CloudSat and CALIPSO could be used to retrieve the optical depth and backscatter phase function (lidar ratio) of aerosols and ice clouds. This methodology lead to the development of a data fusion product publicly available at the ICARE archive center using the Synergized Optical Depth o...

We present Calipso, an interactive method for editing images and videos in a physically-coherent manner. Our main idea is to realize physics-based manipulations by running a full physics simulation on proxy geometries given by non-rigidly aligned CAD models. Running these simulations allows us to apply new, unseen forces to move or deform selected objects, change physical parameters such as mas...

Abstract. Space profiling lidars offer a unique insight into cloud properties in Earth's atmosphere and are considered the most reliable source of total (column-integrated) amount (CA), true (geometrical) top height (CTH). However, lidar-based climatologies suffer from infrequent sampling: every n days, only along ground track. This study therefore evaluated four lidar missions, namely CALIPSO ...

In this study, we apply a clustering algorithm to ISCCP Cloud Optical Thickness – Cloud Top Pressure histograms in order to derive Weather States (WS) for the global domain. The cloud property distribution within each WS is examined and the geographical variability of each WS is mapped. Once the global weather states are derived, a combination of CloudSat/CALIPSO vertical cloud structure retrie...

[1] The SEA‐CALIPSO experiment in December 2007 incorporated a sea‐based airgun source, and seismic recorders both on Montserrat and on the adjacent sea floor. A high quality subset of the data was used for a first arrival P‐wave velocity tomographic study. A total of more than 115,000 traveltime data from 4413 airgun shots, and 58 recording stations, were used in this high‐ resolution tomograp...

An important component of the AVHRR PATMOS-x climate date record (CDR)—or any satellite cloud climatology—is the performance of its cloud detection scheme and the subsequent quality of its cloud fraction CDR. PATMOS-x employs the NOAA Enterprise Cloud Mask for this, which is based on a naïve Bayesian approach. The goal of this paper is to generate analysis of the PATMOS-x cloud fraction CDR to ...

26 The steady northeast trade winds impinge on the Hawaiian Islands, producing 27 prominent island wakes of multi-spatial scales from tens to thousands of kilometers. 28 Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) reveal 29 rich three-dimensional structures of low-level clouds that are induced by the islands, 30 distinct from the background environment. The clou...
