Abstract After the successful launches of first two polar-orbiting satellites in a new Fengyun-3 (FY-3) series, FY-3A/B, into morning- and afternoon-configured orbit May 2008 November 2010, respectively, China will launch its next three before 2020. The Microwave Temperature Sounder (MWTS) on FY-3A/B has four channels that have same channel frequency as 3, 5, 7, 9 Advanced Sounding Unit-A (AMSU-A). Thus, quality brightness temperature measurements from FY-3A MWTS can be assessed using AMSU-A...
[1] The measurements from FY-3 MicroWave Humidity Sounder (MWHS) are compared with the data NOAA-18 Microwave (MHS) under various atmospheric and surface conditions. A quality control (QC) procedure is applied to allow comparison be conducted separately for outliers nonoutliers. The QC algorithm includes a gross error check, instrument noise spikes through equivalent differential temperature, an O-B biweighting where O represents satellite observations B model-simulated brightness...
Abstract We study effects of the interplanetary magnetic field (IMF) orientation on terrestrial tail bow shock location and shape by using global MHD magnetosphere model empirical models. It is shown that cross section well approximated an ellipse with direction major axis roughly perpendicular to IMF clock angle direction. With increasing angle, eccentricity increases for northward but decreases southward IMF.
Abstract In this study we use the bow shock crossings contained in Space Physics Data Facility database, collected by four spacecraft (IMP 8, Geotail, Magion‐4, and Cluster1) to analyze effect of interplanetary magnetic field (IMF) B y component on position shape. Although IMF z is usually considered much more geoeffective than , find that dayside responsive eastward north‐south one. We believe explanation lies changes induces magnetopause location shape, which largely compensate...
Abstract Atmospheric Infrared Sounder (AIRS) provides twice-daily global observations from which total column ozone data can be retrieved. However, 20% ~ 30% of AIRS are flagged to bad quality. Most the were identified have precipitable water (PW) errors, defined by ratio between PW errors and retrieval exceeding 35%. It was found that most within hurricanes because extremely low PW, is also retrieved observations. In this study, a new ratio, error divided National Centers for Environmental...
In this paper, we consider a one-dimensional thermoelastic-Bresse system with delay term, where the heat conduction is given by Cattaneo’s law effective in shear angle displacement. We prove that well-posed using semigroup method, and show, multiplier dissipation induced strong enough to exponentially stabilize presence of “small" when stable number zero.
