Councillor James Noakes and ET's Lewis John talk to BBC Radio Merseyside about about pollution levels in Liverpool city centre. Lewis and the Smogmobile monitored the busiest roads within the city on Clean Air Day 2019.
From June to October, the burning of agricultural fields in southern Africa creates smoke that blows west across the southeastern Atlantic Ocean and reaches Brazil, over 4,500 miles away. Using Micro Pulse LiDAR (MPL) and other instruments, researchers at the Atmospheric Radiation Measurement (ARM) user facility on the remote island of Ascension, operated by the U.S. Department of Energy, collected data for 16 months to help understand how these airborne particles impact the climate.

Working for an Environmental Company, ETs Engineers are keen to do their bit to keep vehicle emissions generated by themselves to an absolute minimum. One long standing ET engineer, Kevin Phillips ditches his diesel van on the edge of the town or city of his job location and bikes in to service the AQ station whenever possible.
Other ET Engineers have taken to getting to work by train with their bike in tow so they can avoid driving at all. One less vehicle on the road, less emissions and more exercise!
At ET we encourage all our staff to think of ‘greener ways to travel to and from their places of work. It’s the small things like this that will collectively make the difference.
The Model T200P & T200UP products combine Blue Light Converter and Chemiluminescence technologies for more accurate and lower maintenance NO-NO2-NOx measurement.

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.
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.
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.
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.

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.
