Meteorological and climate analysis centres across the Southwest Pacific are indicating above average numbers of tropical cyclones (TC) for the 2015–16 season (November 2015 to April 2016). The 30-year average number of all Southwest Pacific tropical storms that formed between 1981-2010 is 12.4 for the November and April TC season. The average number of storms that developed into named TCs ...
Micro pulse style lidars are active remote sensing tools proven to be highly useful in atmospheric research. This style of backscatter lidar has been around for decades; however, incremental improvements in photon counting, sensitivity, polarization, optical filters, coatings, and precision machining of each element support increasingly accurate analysis. Each iteration of the sensor provides a ...

With a very modest investment in computer hardware and the open-source local data manager (LDM) software from University Corporation for Atmospheric Research (UCAR) Unidata Program Center, a researcher can receive a variety of NEXRAD Level III rainfall products and the unprocessed Level II data in real-time from most NEXRAD radars in the USA. Alternatively, one can receive such data from the ...
The assessment of local and regional impacts of climate change often requires downscaling of general circulation model (GCM) projections from coarser GCM-scale to finer local- or catchment-scale spatial resolution. This paper provides an assessment of two downscaling approaches for simulation of daily rainfall over Sydney, Australia. The two downscaling alternatives compared include a ...
In the last few decades, due to the potentially serious impacts upon the atmosphere, earth, and ocean the climate change issue become internationally disputable subject among many scientists including various specialists such as climatologists, atmospheric researchers, oceanographers, hydro–meteorologists, agriculturalists, in particular, local administrators in addition to politicians, as ...
Based on the Haihe river basin National Centers for Environmental Prediction/National Center for Atmospheric Research reanalysis data from 1948 to 2010 and the precipitation data of 53 hydrological stations during 1957–2010, this study analyzed the variation of water vapor content and precipitation, and investigated the correlation between them using several statistical methods. The ...
Close to McMurdo Station in Antarctica, researchers from the University of Colorado, Boulder and the National Center for Atmospheric Research are investigating methods to measure the accumulating snowfall in the harsh Antarctic environment. These measurements are important to better understand the potential for sea level rise in the future due to climate change. Measuring snowfall in the ...
An intriguing dichotomy has developed within the field of atmospheric and climate research. On the one side, it has become common practice to examine pessimistic future scenarios of anthropogenic pollutant emissions and their environmental impacts. Not surprisingly, compared to the alternative “best guess” or “maximum feasible reduction” emissions scenarios, the pessimistic scenario simulations ...
In many temperate-zone ecosystems, seasonal changes in environmental and biological factors influence the dynamics and magnitude of surface–atmosphere exchange. Research was conducted between July and October 2001 to measure growing season surface-layer fluxes of CO2 in a Deyeuxia angustifolia dominated wetland on the Sanjiang Plain in northeastern China. Seasonal fluctuation and daily change in ...
Climate change impacts are among the future significant effects on the socioeconomic, cultural and political affairs of any society, whether as towns, cities, regions, countries and the world at large. It is therefore necessary to predict future impacts by modelling logical and rational scenarios. Such scenarios are available internationally in the Special Report on Emission Scenarios (IPCC) and ...
The fashion industry has stepped into the digital era. There are a great number of firms moving to be the digital companies with the major business process all being supported by the internet (Hajji et al., 2012; Bruce and Daly, 2011). A recent study from Mintel (2012) finds that online fashion purchase has increased by 152% in the UK over the last five years. The aim of this study is to ...
Abstract The Boulder Atmospheric Observatory (BAO) is a unique research facility for studying the planetary boundary layer and for testing and calibrating atmospheric sensors. The facility includes a 300 m tower instrumented with fast- and slow-response sensors, a variety of remote sensing systems, and a real-time processing and display capability that greatly reduces analysis time for ...
A bibliometric method was developed to investigate the aerosol research based on the papers from 1991 to 2009 in Science Citation Index Expanded, the Thomson Reuters. The analysed aspects covered scientific output and citation tracking on the basis of journal patterns; country; institute and author research performances. Improved indicators Peak–Year Citation per Publication and Relative ...
The influence of sea-land breezes (SLBs) on the spatial distribution and temporal variation of particulate matter (PM) in the atmosphere was investigated over coastal Taiwan. PM was simultaneously sampled at inland and offshore locations during three intensive sampling periods. The intensive PM sampling protocol was continuously conducted over a 48-hr period. During this time, PM2.5 and ...
APi-TOF Reinvented – IONICON APi-TOF Receives 2018 “TASIA” After CHARON scored an innovation award from the “The Analytical Scientist” in 2017, we couldn’t believe our eyes when the game-changing IONICON APi-TOF was awarded a “TASIA” in 2018. Each year The Analytical Scientist Innovation Awards (TASIAs) showcase those technologies driving the ...

Weeks before the athletes took to the ice and snow at the 2018 Winter Olympics in South Korea, Dr. Duncan Axisa was in the mountains around PyeongChang, studying ice-forming particles. Later in the year, Axisa traveled to India to study monsoon clouds, and to France to participate in a trans-national ice-nucleation experiment. Axisa and his team travel around the globe to help scientists better ...
Team of the University of Innsbruck and an IONICON PTR-TOFMS aboard NASA research aircraft An international team coordinated by NASA has recently investigated air pollution over the Korean peninsula. Two of IONICON’s PTR-TOFMS instruments were used to monitor volatile organic compounds (VOCs) in real-time aboard NASA’s DC-8 Flying Laboratory. The data gathered by scientists from the ...
Remotely sensed data and a one-dimensional hydrophysical model were used to study the seasonal dynamics of surface plant pigments concentration in the Ligurian-Provençal basin. The variations of phytoplankton biomass were estimated from the observations of the Coastal Zone Color Scanner (1978–1986) and Sea-viewing Wide Field-of-view Sensor (SeaWiFS) (September 1997 to October ...
