Hygroscopicity of the submicrometer aerosol at the high - alpine site Jungfraujoch , 3580 m a . s . l . , Switzerland
Data from measurements of hygroscopic growth of submicrometer aerosol with a hygroscopicity tandem differential mobility analyzer (HTDMA) during four campaigns at the high alpine research station Jungfraujoch, Switzerland, are presented. The campaigns took place during the years 2000, 2002, 2004 and 2005, each lasting approximately one month. Hygroscopic growth factors (GF, i.e. the relative ch...

متن کاملMeasured and modelled cloud condensation nuclei number concentration at the high alpine site Jungfraujoch
Atmospheric aerosol particles are able to act as cloud condensation nuclei (CCN) and are therefore important for the climate and the hydrological cycle, but their properties are not fully understood. Total CCN number concentrations at 10 different supersaturations in the range of SS = 0.12–1.18% were measured in May 2008 at the remote high alpine research station, Jungfraujoch, Switzerland (358...
متن کاملIce residual properties in mixed‐phase clouds at the high‐alpine Jungfraujoch site
Ice residual (IR) and total aerosol properties were measured in mixed-phase clouds (MPCs) at the high-alpine Jungfraujoch research station. Black carbon (BC) content and coating thickness of BC-containing particles were determined using single-particle soot photometers. The ice activated fraction (IAF), derived from a comparison of IR and total aerosol particle size distributions, showed an enr...
متن کاملthe trace of translators ideology in literary translations: a case study of persian translation of the scaret letter
رساله ی حاضر تلاشی است برای بررسی مبحث ایدئولوژی در ترجمه ادبی و تاثیرات آن بر کار مترجم، اعم از گزینش واژگان و ساختارهای دستوری؛ با تمرکز بر تحلیل انتقادی گفتمان در متن مبدأ و متن مقصد، که در این رساله متن مبدأ رمان داغ ننگ اثر ناتانیل هاوثورن و ترجمه فارسی سیمین دانشور به عنوان متن مقصد مورد بررسی قرار گرفته است. تجزیه و تحلیل رمان های مورد نظر به طور عمده بر اساس مدل پیشنهادی فرحزاد(2007) بر...
