"This book examines the effect of human activities on atmospheric ozone, namely the increase of tropospheric ozone and the general diminution of stratospheric ozone and the production of the Antarctic ozone hole. Also discussed is the role of remote sensing techniques in the understanding of the effects of human activities on atmospheric ozone as well as in the development of social and political awareness of the damage to the ozone layer by man-made chemicals, principally CFCs."

"This companion provides a collection of frequently needed numerical data as a convenient desk-top or pocket reference for atmospheric scientists as well as a concise source of information for others interested in this matter. The material contained in this book was extracted from the recent and the past scientific literature, it covers essentially all aspects of atmospheric chemistry. The data are presented primarily in the form of annotated tables while any explanatory text is kept to a minimum."

"The book provides an up-to-date, in-depth survey across the entire field of atmospheric science, including atmospheric dynamics, radiation, cloud physics, chemistry, climate, numerical simulation, remote sensing, instruments and measurements, as well as atmospheric acoustics.The authors have provided a readily comprehensible and self-contained presentation of the complex field of atmospheric science. The topics are of direct relevance for aerospace science and technology. Future research challenges are identified."

"Dinitrogen monoksida (N2O) yang diemisi dari berbagai proses industri dan aktivitas pertanian merupakan salah satu gas yang memberikan kontribusi tinggi dalam pemanasan global dan tergolong ke dalam kategori gas yang berbahaya. Reduksi gas N2O dilakukan menggunakan teknologi biofilter yang efektif dan efisien dalam mengontrol emisi udara. Zeolit Alam Lampung teraktivasi digunakan sebagai media filter karena memiliki porositas yang tinggi. Nitrobacter winogradskyi digunakan untuk mengoksidasi N2O menjadi gas yang tidak berbahaya. Tujuan penelitian ini ialah untuk mengkaji pengaruh dari penambahan kultur bakteri terhadap reduksi gas dan untuk mendapatkan kondisi operasi yang optimum dalam biofiltrasi dengan cara memvariasikan pH awal media, yaitu pH 4, 5, 6, 7, dan 8. Biofilter dioperasikan selama 24 jam dengan konsentrasi gas yang digunakan ialah 15000 ppm N2O dalam udara dan laju alir sebesar 88 cc/menit. Efisiensi reduksi tertinggi yang diperoleh sebesar 94,73%, yang dicapai pada variasi pH awal 7. Inokulasi bakteri ke dalam media filter menghasilkan 32,03% rata-rata efisiensi reduksi lebih tinggi daripada sistem tanpa inokulasi. TPC menunjukkan terjadi penurunan jumlah bakteri setelah biofiltrasi. SEM menunjukkan terjadi penebalan biofilm selama operasi. Isotermis Langmuir menghasilkan qm maksimum sebesar 2,873×10-3 g N2O/g zeolit pada pH awal 7 dan KL maksimum sebesar 1,709×10-3 m3/g pada variasi tanpa inokulasi mikroba. Isotermis Freundlich menghasilkan n dan Kf maksimum sebesar 5,625 dan 8,86×10-5 m3/g secara berurutan pada variasi tanpa inokulasi mikroba.

Nitrous oxide (N2O) which is emitted from various industrial process and agricultural activities is one of several gases that gives highest contribution in global warming and also categorized as a dangerous gas. Removal of N2O could be achieved by biofilter technology that is effective and efficient in controlling air emission. Activated Lampung Natural Zeolite was utilized as filter media because of its high porosity. Nitrobacter winogradskyi used to oxidize N2O into harmless gas. This research aims to study the effect of bacteria culture addition in biofiltration and determine the optimum operation condition by adjusting initial pH of media to pH 4, 5, 6, 7, and 8. Biofilter was operated for 24 hours with gas concentration was 15,000 ppm N2O in air and gas flow rate was maintained at 88 cc/minute. The maximum removal efficiency obtained was 94.73%, achieved at initial pH 7. Furthermore, inoculation bacteria into filter media yield 32.03% higher average of removal efficiency than system without inoculation. TPC showed decreasing amount of bacteria after biofiltration. SEM showed biofilms grow thicker during operation. Langmuir isotherm obtained maximum qm at initial pH 7 was 2.873×10-3 g N2O/g zeolit and maximum KL at system without bacteria inoculation was 1.709×10-3 m3/g. Freundlich isotherm obtained maximum n and Kf were 5.625 and 8.86×10-5 m3/g respectively at system without bacteria inoculation."
