Air quality in the Himalayas: Workshop on Simulating and Forecasting Atmospheric Conditions


The Hindu Kush Himalayan (HKH) region suffers from severe air pollution.

UNEP’s Atmospheric Brown Cloud (ABC) project has identified the HKH foothills region as one of the hotpots of the globe in terms of poor air quality. Indoor and outdoor air pollution contributes to 2 million premature deaths a year in South Asia.

Furthermore, studies have shown how air pollution affects the hydrological cycle in the HKH region, with significant effects on monsoon patterns. Air pollution is also a key factor behind accelerating glacier melt and has an adverse impact on agriculture, tourism and livelihoods.

In this context, a tutorial workshop on the use of the Weather Research and Forecast with Chemistry (WRF-Chem) with 20 participants from the HKH region was successfully conducted at the headquarters of the International Centre for Integrated Mountain Development (ICIMOD) in Kathmandu, Nepal from 1 to 5 June.

The workshop, which was jointly hosted by ICOMOD and IASS, took place in the framework of the project ‘Sustainable Atmosphere for the Kathmandu Valley’ (SusKat). SusKat was initiated to conduct a comprehensive assessment of various aspects of air pollution in the Himalayan region, with a focus on the Kathmandu Valley.

The workshop aimed to boost the capacities of atmospheric scientists in the region. “This training will provide the participants with technical knowledge and help them understand the modelling framework for using the WRF-Chem model over the HKH region,” said Regional Programme Manager Dr Arun Bhakta Shrestha during the opening at ICIMOD.

The workshop enabled atmospheric modellers in the region to contribute insights from a local/regional perspective, thus enhancing the existing body of knowledge on atmospheric issues such as air quality and climate change. It also opened up possibilities for future collaboration among participants on cross-border atmospheric issues.

Weather Research and Forecasting (WRF) is the latest-generation open-source meteorological model designed to serve both atmospheric research and operational weather forecasting needs. It was developed collaboratively by several agencies in the United States, including the National Oceanic Atmospheric Administration (NOAA)/NCEP, NOAA/ESRL, and the National Center for Atmospheric Research (NCAR), and has been used by over 20 000 users in 130 countries.

WRF-Chem is a version of WRF that simulates the emission, turbulent mixing, transport, transformation and fate of atmospheric trace gases and aerosols. It is particularly well-suited to simulating or forecasting atmospheric conditions where there are interactions between atmospheric chemistry and meteorology, for example, when air pollutants affect raindrop formation or when haze affects atmospheric heating and cooling. There are 3 000 registered users of WRF-Chem worldwide.

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

Im Focus: New Products - Highlights of COMPAMED 2016

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
