The waters of the Bering and Chukchi seas, as well as the De Long Strait, are investigated based on the data obtained in August 2013 during the scientific expedition of the Far Eastern Floating University on the research vessel Professor Khlyustin. Chlorophyll a concentrations calculated from MODIS-Aqua and VIIRS satellite data by ocean color and obtained by means of shipboard flow-through fluorometric measurements are comparatively analyzed. Vessel data are corrected for standard spectrophotometric measurements and the vertical depth distribution of phytoplankton. It has been found that, in the waters of the Eastern Arctic, satellite radiometers showed overestimated chlorophyll a concentrations in the upper seawater layer visible from the satellite. This is associated with the additional contribution of colored dissolved organic matter in the sea surface color. In the De Long Strait, satellite measurements incorrectly estimate the depth integrated chlorophyll a concentration, since the bulk of phytoplankton cells at a chlorophyll a concentration of 10–20 g/L is at depths of 25–30 m with luminosity of 5%. 相似文献

The results of an analysis of the annual variation of the planetary boundary layer (PBL) height in the continent-ocean transition zone determined from lidar and meteorological data are presented. Means of the height and its variances are calculated in a month-long window. The PBL heights reconstructed from these measurements are found to differ substantially in the spring and summer seasons. These results are explained by the influence of dust storms and cyclones, which are the most intense in these seasons, on the structure of aerosol in the atmosphere. 相似文献

The paper describes a lidar and presents the results of lidar sensing of the vertical ozone distribution (VOD); the lidar measurements are analyzed together with data from a network of meteorological stations situated along the 132° E meridian. VODs over Primorye and Japan in the winter period are compared. An analysis showed that an interrelation exists between the subtropical jet stream and the structures of VOD and tropopause inversion layer. Specifically, the region of the VOD local maximum above the tropopause is in the upper part of the tropopause inversion layer and the width of the maximum depends on the distance from the core of the subtropical jet stream. It is found that the local ozone minimum in the lower stratosphere corresponds to the local minimum of the squared Brunt-Vaisala frequency within this same altitude range in the winter season, when two tropopauses frequently overlap. It is conjectured that the local ozone maximum and tropopause inversion layer may be associated with mixing processes in the layer where stratospheric and tropospheric circulation cells come into contact near the core of the subtropical jet stream. 相似文献

The distribution functions of atmospheric aerosol obtained on the basis of lidar sounding and photometric measurements over
marine water areas in continental and transition zones are analyzed. Changes in the microphysical parameters of the distribution
function in the continent-ocean transition zone with height are considered on the basis of data taken from three-frequency
lidar sounding. Specific features of changes in the particle size distribution with height during intense dust storms and
records of volcanogenic aerosol in the tropopause region in the summer of 2008 are described. 相似文献
