Air Pollution Patterns Mapping of SO 2 , NO 2 , and CO Derived from TROPOMI over Central-East Europe The analysis of changes in the level of air pollution concentration allows for the control of air quality and its compliance with the normative requirement... B Wieczorek - 《Remote Sensing...
Key challenges to modelling the coupled terrestrial carbon–nitrogen cycles arise from the need to account for micro-scale processes to represent and quantify important N fluxes, uncertainties in the representation of key carbon–nitrogen cycle couplings at the ecosystem scale, and vagaries in the ...
In the Los Angeles Air Basin, mixed conifer forests and chaparral watersheds with high smog exposure are N saturated and exhibit the highest streamwater NO3/- concentrations for wildlands in North America. High-elevation alpine watersheds in the Colorado Front Range and a deciduous forest in ...
A cryogenic air separation system which is subject to periods of significant changes in product demand is controlled during such periods to minimize the impact of transient operation on product purity. A double- column distillation system is utilized in which a nitrogen-rich liquid is withdrawn from...
The relationship between seasonal variations of total-nitrogen and total-phosphorus in rainfall and air mass advection paths in Matsue, Japan We collected rainwater samples from every rainfall in Matsue, Japan in order to study variations of nitrogen and phosphorus concentrations over time. The s......
A Nationwide Nitrogen Deposition Monitoring Network (NNDMN) containing 43 monitoring sites was established in China to measure gaseous NH3, NO2, and HNO3 and particulate NH4 and NO3 in air and/or precipitation from 2010 to 2014. Wet/bulk deposition fluxes of Nr species were collected by precipit...
- 《Water Air & Soil Pollution》 被引量: 343发表: 2004年 Phosphorus budgets and riverine phosphorus export in northwestern Ohio watersheds. Phosphorus (P) budgets for large watersheds are often used to predict trends in riverine P export. To test such predictions, we calculated annual P ...
A series of 26 high-resolution $(0.01 cm^{-1})$ room-temperature spectra of pure $CH_{4}^{+} CH_{4}$ in dry air and $CH_{4}$ in dry nitrogen was recorded in the $2700-3200 cm^{-1}$ spectral region with a signal-to-rms noise of 2000, using the Fourier transform spectrome...
Ji et al. used Ar/HMDSO in a cylindrical DBD in air (curtain-type, see Fig. 7b) to deposit hydrophobic coatings on PET fiber [114]. Morent et al. used an enclosed parallel-plate DBD operating in AC 50 kHz to obtain plasma polymerized coatings on PET films using Ar/HMDSO/air ...
fish fitted with acid-washed tubing with suction provided by an acid-washed Teflon bellows pump (Dellmeco). Seawater was pumped directly into a purpose-built clean-air laboratory container with positive air pressure maintained via inward airflow passed through a high-efficiency particulate air filter...
