[1] On five occasions spanning the Asian Pacific Regional Aerosol Characterization Experiment (ACE-Asia) field campaign in spring 2001, the Multiangle Imaging Spectroradiometer spaceborne instrument took data coincident with high-quality observations by instruments on two or more surface and airborne platforms. The cases capture a range of clean, polluted,(More)
OBJECTIVES The purpose of our study was to detect early clinical and laboratory signs that help to discriminate macrophage activation syndrome (MAS) from active systemic juvenile idiopathic arthritis (SJIA) without MAS. METHODS Our retrospective study was based on reviewing the medical charts of the children admitted to the rheumatology department with(More)
BACKGROUND Systemic juvenile idiopathic arthritis (SoJIA) is the most striking form of juvenile idiopathic arthritis. The aim of our study was to evaluate the clinical responses and outcomes of children with SoJIA to IL-6 blockade using two different tocilizumab (TCZ) treatment protocols designed for milder and more severe SoJIA patient groups, and evaluate(More)
We use CALIOP nighttime measurements of lidar backscatter, color and depolarization ratios, as well as particulate retrievals during the summer of 2007 to study transatlantic dust properties downwind of Saharan sources, and to examine the influence of nearby clouds on dust. Our analysis suggests that (1) under clear skies, while lidar backscatter and color(More)
1. INTRODUCTION The Multi-angle Imaging SpectroRadiometer (MISR) instrument was launched into polar Earth orbit aboard NASA's Terra satellite on December 18, 1999. MISR contains 9 pushbroom cameras pointed at nadir and along-track view angles of 70.5º, 60º, 46.1º, 26.1º forward and backward of nadir, each with spectral bands at 446, 558, 672, and 866 nm.(More)
We carry out an investigation of the influence of particle alignment on the scattering properties of mineral dust layers. Our modelling indicates that in addition to modifying optical thickness, the alignment can significantly alter the scattering properties, including polarization. Influence of the alignment on remote sensing retrievals is also examined,(More)
