After an episode of poor air quality last week, Sam is joined by Will Morgan and Eoghan Darbyshire to chat about all things air pollution.

The conditions required for such UK air pollution events, the sources and the health impacts are all discussed. Was all the media hype justified? How often do these events occur? What's the outlook over the next few weeks? Find out by listening to this episode of the Barometer!

Jennifer Muller chats to Will Morgan and Michelle Cain (@civiltalker), from the University of Cambridge, after the Royal Meteorological Society's Atmospheric Chemistry Special Interest Group meeting on "When the sun goes down: Atmospheric chemistry at night".

They discuss why atmospheric scientists are interested in what goes on at night, how that differs with the day and what their personal highlights were from the day/night. 

There is also some bonus discussion on geoengineering, where we find out that diamonds are a geoengineer's best friend.

A Stormy Valentines

On a stormy Valentine’s Day, Sam is joined by Professor David Schultz and Tim Slater from the Centre for Atmospheric Science at the University of Manchester, to discuss the recent bad weather that we have been having.

Dave and Tim reflect on what has been a rather tumultuous week, which unfortunately looks set to continue. So wrap up warm, and hold your loved one’s tight, it’s going to be a wet and windy Valentine’s night!

Is it raining in your heart?

After the Science

In this episode of the Barometer, Sam catches up with Dr John Broderick from the Manchester Tyndall Centre to talk about science and policy.

Following on from the GAUGE series of podcasts, we thought it would be interesting to find out what occurs once the science has been handed over to the policy makers, and John gives us a fascinating insight into what happens once the data has been collected and the analysis is complete. 

A bureaucrat at work.

In the first of a series of podcasts, Gary Llyod reports on the INUPIAQ (Ice NUcleation Process Investigation And Quantification) Project, which is based in the Swiss Alps, at the Jungfraujoch (3571m), Shilthorn (2970m) and Kleine Scheidegg (2061m) sites. Over the next few weeks, these episodes will give an insight into both the instruments and the scientists that are relied upon to provide us with accurate measurements of aerosol particles, cloud droplets and ice crystals that are invisible to the naked eye. 

In this episode Gary talks to Dr Keith Bower from the Centre for Atmospheric Science at the University of Manchester about his role in the INUPIAQ campaign, James Bond, and the importance of upwind and downwind measurements. 

George Lazenby clearly isn't impressed by Gary's carrier bag.

In this latest episode of the Barometer, Sam talks to Dr Matt Rigby from the School of Chemistry at the University of Bristol about the role that models will have to play in the GAUGE project.

As well as talking about a modeller’s wish list, Matt and Sam also talk about the Advanced Global Atmospheric Gases Experiment (AGAGE) network, and what exactly it is that modellers do whilst the instrument scientists are out getting the data.


To avoid confusion, this is not the kind of model that we are talking about.

In this episode of the Barometer, Sam catches up with Dr Hartmut Bösch, from the Earth Observation Science Group at the University of Leicester to discuss how satellites will be used during the GAUGE project.

Hartmut and Sam chat about the two main satellite instruments that will be used during GAUGE: the Infrared Atmospheric Sounding Interferometer (IASI) on board the MetOp-A satellite, and the Greenhouse gases Observing SATellite (GOSAT), and also just generally extoll the beauty of remote sensing from space. 

The MetOp-A satellite; ain't she a beauty.

GAUGE: From the Air

In this episode of the Barometer, Jen catches up with Dr Grant Allen, from the Centre of Atmospheric Science at the University of Manchester, to discuss the air borne aspects of the GAUGE campaign.

As well as talking about how aircraft measurements from the UK's Atmospheric Research Aircraft will be used to help constrain emission estimates across the whole of the UK, Grant also talks about a potential dedicated flight campaign that encompasses the Northern conurbations of Leeds, Liverpool, and Manchester AKA the Robbie Fowler Triangle. 

Dr Grant Allen and his marvellous flying machine!

GAUGE: From the Sea

In this episode of the Barometer, Jen catches up with Drs Eiko Nemitz and Carole Helfter from the NERC Centre for Ecology and Hydrology near Edinburgh, to discuss the rather novel use of a ferry for helping to quantify UK emissions during the GAUGE project.

As well as chatting about the relative merits of such maritime operations, Eiko and Carole also discuss some of the measurements that they are involved in on the land, including from the rather impressive BT tower.

Sadly the QE2 was unavailable for research purposes...

In this episode of the Barometer, Jen catches up with Professor Simon O'Doherty from the University of Bristol, to discuss the ground-based aspect of the GAUGE project.

Amongst other things, Simon and Jen discuss the importance of how measurement sites such as those from the UK Deriving Emissions linked to Climate Change (DECC) Network will help to quantify the UK emissions during the GAUGE project. Simon also talks about the Advanced Global Atmospheric Gases Experiment (AGAGE) network, specifically the Mace Head site in Ireland for which he is the principal scientist. 

The Mace Head site is located in an isolated coastal area of county Galway, with a strong marine influence and few local emission sources.
