ET Managing Director, Duncan Mounsor, takes to the train in a bid to decrease his carbon footprint

As part of our ongoing commitment to encouraging a more healthy and environmentally friendly way to travel to work, ET’s MD’s route to work on Friday 30th Nov was quite different from the usual drive from Cheltenham to Stroud.     

Leaving his house at 0705, Duncan ran to Cheltenham train station (1.5 miles) where he grabbed a coffee from the Green Coffee Machine and hopped on the next train to Stroud. From there he ran from Stroud station to ET’s office (1.75 miles). After a quick shower and change of clothes he was at his desk ready for work at 0845. Duncan says “ I really enjoyed traveling to work today knowing that, not only was I contributing to one less car on the road for the day but I was getting my daily running fix in too!” Going forward, Duncan is aiming to do this once a week, when his schedule allows.

ET supplied analysers equip Birmingham 'Supersite'

The NERC funded investment will see eight universities led by the NERC Centre for Atmospheric Science (NCAS) create the network of advanced A Q monitoring instruments to detect harmful air pollutants and their sources in greater detail than ever before. The research will provide essential information that will affect policy decisions which will lead to cleaner, safer, air.

As well as analysers to detect toxic air pollutants, the network includes new instruments to detect a variety of greenhouse gases and ozone-depleting chemicals, in order to help the UK comply with legally-binding targets set out in the Climate Change Act.

For the Birmingham site, ET have supplied MCERTS approved SO2, direct NO2, NOy Teledyne API analysers and two Los Gatos Research enhanced performance analysers for the measurement of CH4, CO2, CO & H2O and NH3, featured in the photo shown.

The network is due to be operational by the end of 2018.

 

ET installs a new monitoring station at a geologically sensitive site in Scotland

Recently some members of ETs project team and an engineer headed up to Dumfries and Galloway to remove an old AQ station and install a brand new one. Sounds fairly straight forward, right?

In fact, there were a number of challenges involved that made the whole thing quite a tricky operation! Not just the coordinating the logistics of it all but also liaising with multiple parties both before and during the onsite work.

The monitoring site in Eskdalemuir, is not only a used by the AURN as background comparison site for measurements of NOx and Ozone on the network but is also a site used by the British Geological Survey to measure seismic activity as well as critical Met logical studies by the Met office. This meant the whole operation was one that needed great care and planning.

It was vitally important that the very sensitive Met equipment powered from the existing station was not off line for more than a day, something that was achieved within the timescale with the equipment only being offline for 6 hours. The weather was also a determining factor on when the operation could go ahead, so time was of the essence.

Not only did they need a 16 ton Tele-Handler to get the enclosure in place but the team had to be really careful to create the least amount of disturbance to the area and keep vehicle movement to an absolute minimum.

We’re pleased to report the project ran smoothly with everything going exactly to plan with all parties involved very happy with the results.

 

Micro Pulse LiDAR and its applications

ET is the official UK and Ireland distributor of Micro Pulse LiDAR. This short video is an excellent introduction to this amazing remote-sensing technology and the wide range of applications it can be used for.

The SmogBox investigates: Brighton’s air quality

You’d expect the air at the seaside to be nice and clean, wouldn’t you?

ET’s Mike Webley, took a stroll along the seafront and some of the back streets in Brighton with our new SmogBox, a mobile, battery powered, NO2 monitoring system, to investigate.

As one would expect, NO2 levels were measured at their lowest along the seafront but never fell below 10ppb. Mikes 6km walk did however peak NO2 levels of almost 100ppb, which were measured on North St, close to the Royal Pavilion.

 

Air quality is typically measured at fixed locations in monitoring stations and the data that’s generated is used to investigate compliance with national limit values. Self-contained, mobile systems such as ET’s zero emissions Smogmobile and now our new SmogBox, enable AQ officers and consultants to investigate potential hot spots where no real-time, permanent monitoring has been carried out.

The SmogBox’s size and portability lend themselves to its use as an investigatory tool for many urban air quality applications. These could include: short-term monitoring at schools, train stations, bus stops and alongside busy roadsides and pedestrian routes.

The SmogBox incorporates the T500U CAPS, fast-responding, high precision, MCERTS approved, direct NO2 analyser as well as GPS tracking and real-time web enabled data collection and visualization.

The SmogBox is housed within a rugged pelican case and is easily transported with its heavy duty wheels for walk around studies, however it can also be towed behind a bicycle in an appropriate buggy or even used in a car, train or even on a bus to investigate NO2 exposure from within inside these modes of transport.

For monitoring on the move, it uses a long life battery pack and for semi-permanent applications it can be powered from mains electricity.

Celebrating Clean Air Day by monitoring NO2 on the way to work..

Happy ‘Clean Air Day’ everyone! ET encouraged all office based employees to be as environmental friendly as possible on their journey to work today.
Sales Director, Mike Webley walked to walk, with the NEW ET NO2 SmogBox and measured the air quality on his way in to the office, completing a 2 mile stretch in total. The first mile is through residential streets, where pollution levels are low, but the subsequent mile is along the busy A419 road, which has considerably higher pollution levels. Mike says, “Normally when I work to walk, for the 2nd mile I normally walk along the Thames and Severn canal, which is away from the road and the pollution, but today with our SmogBox, I wanted to demonstrate the use of pollution monitoring equipment and how these real time DEFRA MCERTS approved equipment can provide good scientific data.

 

ET supplies cutting-edge drone based air pollution monitoring technology in the UK.

DOAS Explained

DOAS stands for Differential Optical Absorption Spectroscopy. The DOAS technique was conceived almost a century ago, and it was applied on research level to air quality monitoring already in the 1970s. In the mid-1980s, the technology was then commercialised and turned into practical and wide-spread use.

The Smogmobile: A Collaboration between the GSMA and the Royal Borough of Greenwich

Back in July this year the Smogmobile was busy helping GSMA and The Royal Borough of Greenwich measure the roadside air quality every minute as it was driven around Greenwich for eight days during two consecutive weeks.

The Smogmobile was used as an experiment to see how a large number of small mobile sensors could potentially map weather and traffic data to understand the causes and fluctuations in air pollution, as oppsoed to the small number of larger fixed AQ stations currently used.
