Background
The Earth System and its interactions with human activities is one of the four 
main themes of the Met Office Science Plan. The Earth System and Mitigation 
Science (ESMS) team has a world-leading track record in the field of 
stratospheric dynamics, atmospheric chemistry, inverse modelling, atmospheric 
aerosols, and the terrestrial carbon cycle. It delivers policy relevant 
research to our government and commercial customers as well as performing 
underpinning research on emissions and gas-phase chemistry and their 
interactions with climate, aerosols and ecosystems.

The Greenhouse Gas Inversion group within ESMS is responsible for maintaining 
our world-leading reputation in the field of verification of regional emissions 
and inverse modelling in general. Understanding current and future changes in 
atmospheric composition due to changes in emissions and climate are important 
to policy customers. The focus is on policy-relevant timescales through 
understanding the atmospheric trends and UK emissions of greenhouse gases (GHG) 
over the last 25 years.

The group uses NAME, the Met Office atmospheric dispersion model, and uses and 
develops the Inversion Technique for Emission Modelling (InTEM) model. The 
group contributes modelling and analysis to international activities such as 
the EU project INGOS and AGAGE (Advanced Global Atmospheric Gases Experiment) 
and actively collaborates with the UK academic community (currently; Bristol, 
Cambridge, Edinburgh, Manchester and Imperial).

The scientist/senior scientist will join ESMS comprising of more than 20 
research scientists. The jobholder will be expected to contribute to the 
development of InTEM and to perform novel research in the field of inverse 
modelling. They will also have opportunities to actively participate in a wide 
range of national and international research activities, such as the NERC 
project GAUGE and AGAGE.

Inverse modelling for estimating emissions uses information from observations 
of atmospheric trace gases (e.g. methane and nitrous oxide), combined with 
estimates of how emissions dilute on route to the measurement site (e.g. 
through the use of NAME). By comparing the modelled time-series of 
concentration with the observations, the modelled emissions can be adjusted to 
maximise the statistical fit between the modelled and observed time-series. Key 
areas of development in inverse modelling are; statistical uncertainty, 
background atmospheric concentrations, the use of prior knowledge or 
information.

Inverse modelling is a rapidly developing area of science with many innovative 
approaches being explored e.g. Monte Carlo Markov Chain methods, statistical 
emulators, principle component analysis, use of satellite data to complement 
surface observations, uses of isotopes to separate emissions from different 
source categories. The successful candidate will work closely with the 
University community (principally Bristol and Cambridge) to develop and 
implement some of these ideas within InTEM. There is also a strong link to 
ADAQ, the Met Office dispersion group, and their use of InTEM for emergency 
response.

The commercial contract with DECC (Dept. of Energy and Climate Change), the 
backbone to the funding, is now in its 15th year (just extended) and encourages 
strong collaboration with the international community, e.g. AGAGE. The AGAGE 
community have twice yearly meetings at various locations around the world and 
the Met Office is an integral part of this programme providing key information 
for the interpretation of the observations. INGOS is a European programme 
requiring strong collaboration with the key inverse modelling groups across 
Europe. GAUGE, a new NERC programme focussed on inverse modelling, offers the 
opportunity for close collaboration with the UK university community.

the work.
Job Purpose
To deliver excellent scientific research in the field of atmospheric inversion 
modelling, to actively collaborate with a wide range of national and 
international organisations and to deliver relevant and timely information to 
our customers.
Job Responsibilities
Contribute to developing and innovatively using InTEM to further improve our 
understanding and quantification of the emissions of key GHGs.
Contribute to the successful delivery of research contracts that have important 
UK and international significance.
To estimate the long-term trends of key GHG and ozone-depleting gases and 
encourage their use through maintaining an external web site.
To present scientific research in peer-reviewed journals and at national and 
international scientific meetings and conferences.
To look for and explore innovative uses of InTEM and NAME within the Hadley 
Centre and more widely both within and outside of the Met Office.
Essential Qualifications, Skills & Abilities
1. Both levels: A strong background (2.1 degree or better) in mathematics, 
physics or related discipline.
2. Both levels: Demonstrated competence in postgraduate research in a 
mathematically based subject area.
For senior scientist: Significant postdoctoral research record.
3. Both levels: Proven ability to develop and use complex numerical models, 
including effective computer programming in FORTRAN, IDL, UNIX and/or Python.
4. Both levels: Evidence of ability to communicate own work to the academic and 
wider communities both orally and in writing. Appropriate publication record 
for stage of career.
Senior Scientist: Demonstrated ability to communicate to specialists and 
non-specialists and to be able to positively interact with them.
5. Both levels: Evidence of ability to work innovatively and independently on 
scientific projects.
Senior Scientist: Evidence of ability to lead scientific project-work and 
enthusiasm to seek and develop new areas of research.
6. Both levels: Evidence of ability to work effectively as part of a small team 
and be able to demonstrate strong positive inter-personal skills.
Desirable Qualifications, Skills & Abilities
1. Experience of inverse modelling.
2. Experience of atmospheric dispersion modelling.
3. Experience of analysing data using complex mathematical models.

Additional Supplementary Information
There will also be opportunities to develop mentoring skills through University 
PhD students and other UK researchers. The location of the position will be at 
the Met Office Exeter HQ.

Opportunities for international and national travel and collaboration with a 
wide range of academic and government organisations.

Please apply against the criteria for which your experience is most 
appropriate. We may additionally sift your application at a level above or 
below the level at which you applied. If successful at passing the sift stage, 
we will inform you at what level we think your experience aligns within the 
invitation to interview letter.

If the successful candidate is currently in a role in the Met Office scientific 
framework, they will ordinarily remain in the role to which they are currently 
mapped.
