Influence of the Arctic Oscillation on the vertical distribution of clouds as observed by the A-Train constellation of satellites

The main purpose of this study is to investigate the influence of the Arctic Oscillation (AO), the dominant mode of natural variability over the northerly high latitudes, on the spatial (horizontal and vertical) distribution of clouds in the Arctic. To that end, we use a suite of sensors onboard NASA’s A-Train satellites that provide accurate observations of the distribution of clouds along wit...

Development of the Hampton University Lidar System and the Realm Lidar Network

Lidar offers a plethora of information on atmospheric aerosols and chemical constituents. However, lidar systems typically work in vacuums, applied to specific applications, such as validation efforts, and with little collaboration with other institutions. In order to alleviate these limitations, the Hampton University (HU) lidar has made steps to join the CREST Lidar Network (originally the RE...

Development of the Hampton University Lidar System and the Crest Lidar Network

As a remote sensing technique, lidar is a staple of atmospheric measurement techniques. Short-wavelength scattering allows measurements from molecular and particle or aerosol components of the atmosphere. These features are of particular importance to studies of weather, climate, and the underlying radiative transfer processes that drive them. Furthermore, these quantities or the scattering pro...

Forest Fire Smoke Layers Observed in the Free Troposphere over Portugal with a Multiwavelength Raman Lidar: Optical and Microphysical Properties

Vertically resolved optical and microphysical properties of biomass burning aerosols, measured in 2011 with a multiwavelength Raman lidar, are presented. The transportation time, within 1-2 days (or less), pointed towards the presence of relatively fresh smoke particles over the site. Some strong layers aloft were observed with particle backscatter and extinction coefficients (at 355 nm) greate...
