  neutral atmospheric
The IPHA method as applied to the 162 kHz measurements made at Panská Ves, allows ionospheric and neutral atmospheric parameters to be studied simultaneously and appears to provide reliable and good quality data.
      
Several non-dynamic, scale-invariant, and scale-dependent dynamic subgrid-scale (SGS) models are utilized in large-eddy simulations of shear-driven neutral atmospheric boundary layer (ABL) flows.
      
In its present stage of development the model is based on the numerical integration of neutral atmospheric flow equations, using an energy-dissipation closure scheme and over a domain that may include vegetation layers.
      
High-accuracy large-eddy simulations of neutral atmospheric surface-layer flow over a gapped plant canopy strip have been performed.

The theory and the procedure of inversion of Earth's neutral atmospheric parameters and bending angles with GPS Occultation data with Abel integral method are introduced. Based on the theory, two methods of ionospheric correction, linear phase correction and linear bending angle correction, are described. Two approaches to determine the upper bound of Abel inversion are discussed. The method for optimizing the measured bending angles on the upper bound are also analyzed. Pre-processing steps of Level2...

The theory and the procedure of inversion of Earth's neutral atmospheric parameters and bending angles with GPS Occultation data with Abel integral method are introduced. Based on the theory, two methods of ionospheric correction, linear phase correction and linear bending angle correction, are described. Two approaches to determine the upper bound of Abel inversion are discussed. The method for optimizing the measured bending angles on the upper bound are also analyzed. Pre-processing steps of Level2 data of UCAR, including transferring the coordinates of GPS and LEO satellites from the coordinate system of ECI to ECEF and low-pass filtering of the phase delay data, are discussed. Last, the computation with data of certain occultation event is done and the results are analyzed. Some conclusions have been drawn.

In Space Geodesy technology.One of the main error sources is atmospheric transmitting delay. The influence of neutral refraction delays ranges from a few meters to a few decameters in the radio wave band. It cannot be eliminated absolutely even through corrections of model at present, especially the part of damp atmospheric refraction in case of its strong randomness. Under spherical symmetric atmospheric profiles, the generating function of neutral atmospheric refraction corrections, which related to...

In Space Geodesy technology.One of the main error sources is atmospheric transmitting delay. The influence of neutral refraction delays ranges from a few meters to a few decameters in the radio wave band. It cannot be eliminated absolutely even through corrections of model at present, especially the part of damp atmospheric refraction in case of its strong randomness. Under spherical symmetric atmospheric profiles, the generating function of neutral atmospheric refraction corrections, which related to the complementary error function has been introduced in this paper,. The mathematical expressions of the generating function has also been discussed in detail. Simultaneously, diversified mapping functions are compared in this paper.

大气传播延迟是空间大地测量技术的主要误差源之一。在射电波段中性大气延迟的影响可从几米到几十米变化 ,即使通过目前某些模型的修正 ,也不能完全消除大气的影响 ,特别是湿大气部分由于变化随机性强 ,很难用模型估计。本文研究了在球对称大气模式下 ,与余误差函数形式相联系的中性大气折射延迟的母函数 ,讨论了与其有关的一些展开式 ,并对各种映射函数进行了比较。

The same inversion method, which does not take the effect of water vapor into account, was applied to processing level2 data of certain occultation event of GPS/MET experiment and CHAMP mission. The profiles of refractivity and neutral atmospheric parameters has been compared with level3 data provided by UCAR and GFZ, respectively. The temperature and pressure profiles are also compared with those from UCAR and GFZ, respectively. Although both pressure profiles are in accordance with the corresponding...

The same inversion method, which does not take the effect of water vapor into account, was applied to processing level2 data of certain occultation event of GPS/MET experiment and CHAMP mission. The profiles of refractivity and neutral atmospheric parameters has been compared with level3 data provided by UCAR and GFZ, respectively. The temperature and pressure profiles are also compared with those from UCAR and GFZ, respectively. Although both pressure profiles are in accordance with the corresponding Level3 data, the temperature profile from GPS/MET is better than that from GFZ. After analyzing the systematic error which exists in the temperature profiles retrieved in both cases, this paper points out that the remnant ionospheric errors and the constrains of the temperature on the upper bound are two factors for it. When retrieving atmospheric parameters profiles from refractivity profiles, to get temperature profile from CHAMP data which is more accordant with the result of GFZ, we need to constrain the temperature on the upper bound with different methods.

采用Abel积分反演算法 ,在干大气模式下 ,分别针对GPS/MET与CHAMP特定掩星事件的Level2数据进行处理 ,得到了相应的折射指数与大气参数廓线。分别将反演结果与UCAR和GFZ公布的结果进行比较 ,证明了反演算法的正确性与通用性。分析了两个温度反演结果都存在系统误差和CHAMP温度反演结果误差较大的原因 ,并提出了改进建议
