It consists of: (i.) modulation of energetic particle fluxes, continuously or sporadically entering Earth's atmosphere; (ii.) ozone formation in the lower stratosphere, initiated by precipitating energetic particles, with different mechanisms for galactic and solar protons; (iii.) modulation of tropopause temperature and humidity by the ozone; (iv) greenhouse warming or cooling, depending of the sign of humidity anomaly. Provided are also evidences confirming validity of this mechanism. The spatial distribution of correlation coefficients of surface temperature with: (i) geomagnetic field intensity,(ii) total ozone and (iii) specific humidity at 150 hPa shows a persistent coherence between all of them over West Antarctica. Moreover, analysis of time series reveals that in this sector the ozone values are permanently lower, while specific humidity near the tropopause remains persistently higher than that in the East Antarctica, during all examined years. This means that during the passed half a century the near surface air temperature in the West Antarctica is warmed (by the increased near tropopause humidity), while in the East Antarctica it is cooled, due to the reduced water vapour making the atmosphere more transparent for the long-wave radiation emitted from the Earth. Thus one of the hotly discussed problems for cooling trends of the Eastern Antarctica, in the context of contemporary global warming, could be easily solved by taking into account the geomagnetic field influence on climate.","PeriodicalId":448231,"journal":{"name":"International Review of Physics","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130840336","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

SnS2 , Cu2S thin films and their mixture were deposited on glass substrates at temperature of 334°C, 283°C and 300°C respectively. XRD studies showed that all the prepared films were polycrystalline in nature with a hexagonal structure and the preferential orientation for Cu2S thin film was along (002) plane , while the preferential orientation for SnS2 thin films was along (101) plane . The absorbance and transmittance spectra have been recorded in the wavelength (310-1100) nm in order to study the optical properties . It was found that the electronic transitions on fundamental absorption edge were direct allowed and the values of the optical energy gap for SnS2 andCu2S was equal to 2.2eV and 2.35eV respectively. Also it was found that the values of the optical energy gap for the mixture decreased with the increase in SnS2 in the mixture from (2.32-2.22) eV. The optical constants which include refractive index and extinction coefficient as a function of photon energy were also studied.","PeriodicalId":448231,"journal":{"name":"International Review of Physics","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116108126","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ground-based station was selected for its high and diverse local agricultural activities contributed to the aerosol content which allows for various parameters such as concentration, size distribution and aerosol optical properties to be investigated by Mie theory. The retrieval algorithm of 24-hour AODs was performed in order to monitor regional impact of biomass burning emission on tropospheric aerosols. Results revealed that open biomass burning was a significant contributor to large carbonaceous aerosols in the vicinity of research site with AOD around 0.6-0.7. Furthermore, the prominence of open burning emission yielded short range aerosol transportation when fine and coarse aerosol particles were accumulated with the minimum and maximum average AODs of 0.2187 and 0.4291, respectively. In addition, the observation provided important insights into the physical and scavenging of aerosols under the influence of regional anthropogenic source and would be great knowledge of aerosol data development. By the lidar technique used in present work, the nocturnal AOD retrieval was advantageously available.","PeriodicalId":448231,"journal":{"name":"International Review of Physics","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123648155","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
