Estimate Total Number of the Earth Atmospheric Particle with Standard Atmosphere Model

The total number of atmospheric particle (AP) is an important datum for planetary science and geoscience. Estimating entire AP number is also a familiar question in general physics. With standard atmosphere model, considering the number difference of AP caused by rough and uneven in the earth surface below, the sum of dry clean atmosphere particle is 1.06962×10⁴⁴. So the whole number of AP including water vapor is 1.0740×10⁴⁴. The rough estimation for the total number of AP on other planets (or satellites) in condensed state is also discussed on the base of it.     

Correlation between the Intensities of Spectral Components of 1/f Noise

We analyze the estimate of the correlation factor between noise intensities at the outputs of two bandpass filters as a parameter that allows us to obtain additional information on the nature of the 1/f noise. The confidence interval is calculated for the experimental evaluation of the correlation factor between readings of noise intensities. Data on noise in GaAs films and also for the numerical model of the 1/f noise as a superposition of telegraphic random processes are presented and discussed.

Ozone Synthesis in an Electric Discharge between Ferroelectric Electrodes at Atmospheric Pressure

This paper deals with studies of the ozone synthesis by means of an ac discharge (50 Hz) between two parallel ferroelectric plates under radial oxygen flow conditions at atmospheric pressure. Bariumtitanate based ceramic with ? ∽ 6000 was used as ferroelectric material. An important feature of this kind of the discharge is the fact that the operating voltage is well one order of magnitude smaller than that of the silent discharge usually used for the O₃ production. Examples of I — U characteristics are discussed. The absorption of light at 253.7 nm wavelength was used to determine [O₃] within and downstream of the discharge as function of the O₂ flow rate. These results have been examined in terms of a kinetic investigation of the O₃ synthesis based on the so-called plug flow model including the particle balance equations of electrons, O atoms, O₂ and O₃ molecules, respectively. Thus, the measured decrease of [O₃] with increasing flow rate can be explained by the increasing influence of the loss of O₃ by convection on the particle balance of O₃. Furthermore it is shown that inside the plasma reactor [O₃] increases with the radius r. Therefore the data for measured spatial average of [O₃] inside the discharge are lower than that of [O₃] in the flowing afterglow. The last values are identical with that of [O₃] at the exit of the discharge.

Diurnal and Seasonal Variations in the Intensities and Peak Frequencies of the First Three Schumann-resonance Modes

We present the results based on long-term continuous Schumann-resonance measurements at the Lehta station. Diurnal and seasonal variations in the peak frequencies and intensities of the first three modes of the electric-and magnetic-field components are obtained. The experimental results are compared with the two-component model of thunderstorm activity and the model constructed with the use of the Optical Transient Detector data.

空气CH4浓度变化及其与CO的相关性

CH4是一种重要的温室气体,在空气中的含量仅次于CO2.化合物之间的相关性在化合物的浓度测量和估算等方面都有重要的意义.通过分辨率为1 cm-1的长开放光路傅里叶变换红外光谱仪测量采样路径内的北京西四环高速公路附近空气CH4和CO透过率光谱,进行非线性最小二乘光谱拟合,计算出待测组分浓度.北京秋季空气CH4浓度变化趋势几乎一样.白天的浓度变化趋势表明城市中人为活动对CH4的排放影响极大,尤其是机动车尾气的排放,而晚上浓度主要是近地面的积累.2005年9月4日到2005年9月10日的连续浓度变化表明北京秋季每天CH4和CO浓度变化趋势相同,它们的浓度变化具有一定的相关性.     

Extended Analysis of Line Positions and Intensities of Ozone Bands in the 2900-3400 cm Region

The 2900-3400 cm⁻¹ spectral range is revisited for an accurate determination of line positions and line intensities of the 3ν₃, ν₁+2ν₃, 2ν₁+ν₃, and 3ν₁ bands of ozone. The fit on 4520 rotational energy levels of (012), (111), (210), (130), (003), (102), (201), and (300) vibrational states determined from observed transitions of cold and hot bands in the 2400-3400 cm⁻¹ region with J_max=65 and K_{a max}=20 gives a r.m.s.=7×10⁻⁴ cm⁻¹ and provides a satisfactory agreement between calculated and observed line positions (dimensionless standard deviation is χ=1.44). The set of 2580 line intensities of 7 rovibrational bands has been measured and fitted with a r.m.s.=6.9% (χ=1.2), leading to the determination of transition moment parameters for these bands. Using these parameters we have obtained more precise estimation for the integrated band intensities S(3ν₃)=1.41×10⁻¹⁹, S(ν₁+2ν₃)=1.28×10⁻²⁰, S(2ν₁+ν₃)=7.91×10⁻²¹, S(3ν₁)=4.72×10⁻²² cm⁻¹/mol cm⁻² at 296 K, with a cutoff 2×10⁻²⁶ cm⁻¹/mol cm⁻². The interactions of the tetrad (003)/(102)/(201)/(300) with the (130) state and the tetrad (040)/(012)/(111)/(210) are studied.

反演波段对DOAS测量大气中O3的性能影响研究

臭氧(O3)浓度通常被认为是一个地方污染水平的基准,所以其绝对值的准确性至关藿要.在差分光学吸收光谱技术(DOAS)对O3的测量过程中,光谱反演波段的选择可直接决定O3浓度的测量准确度.文章主要研究了在不同光谱波段O3特征吸收结构和差分光学厚度(D')的不同,在不同光谱波段O3浓度反演的干扰来源以及影响程度,确定了实际检测时大气消光对不同波段光强的影响,最后通过对多种污染物标准气体进行了同时临测,计算出标准气体在不同光谱分辨率不同O3浓度时的测量误差,确定了对O3的最适用光谱波段范围.在此波段既能够实现对痕量气体的准确定性定量,又能达到测量所需要的高灵敏度,强选择性和适用的时间分辨率.

We show the possibility of retrieving ozone-density and atmospheric-temperature profiles using the measurements of ozone absorption spectra in two lines with different temperature dependences. Using ozone absorption line measurements with an accuracy that can actually be reached in modern experiments, we demonstrate the possibility of retrieving few points in ozone-temperature and ozone-density profiles with vertical resolution of the order of 6 km, which is usual for microwave sounding.
