Report : IWGGMS-7-­Yukio­Yoshida,­­­Researcher,­Satellite­Remote­Sensing­Reserach­Section,­­Center­for­Global­Environmental­Research­at­NIESThe Seventh International Workshop on Greenhouse Gas
Measurement from Space (IWGGMS-7) was held from May 16 to May
18, 2011. The workshop was first organized in April 2004 in Tokyo,
Japan, and has been held almost annually ever since. When it started it
was also around the time when the research papers on carbon dioxide(CO2) and methane (CH4) observation results from satellite sensors,
such as AIRS*1 and SCIAMACHY*2, started to appear in journals, and thedevelopment of satellites for greenhouse gas measurement purpose,such as GOSAT and OCO*3, also started to be fully in progress.
Since then, GOSAT was launched in 2009, and it was followedby the expansion of TCCON*4, the network of ground-based highresolution Fourier Transform Spectrometer observations witha purpose to validate outcomes of these satellite observations.
The greenhouse gas measurement using airplanes (CONTRAIL *5,

CARIBIC*6, HIPPO*7) also made its progress. As such, while the carbon
cycle related observation activities are growing, the number ofparticipants to IWGGMS is also growing bigger each time. This year,
150 researchers attended the workshop and made about 100 oral andposter presentations. It could be also because the venue for this year's
IWGGMS-7 was the University of Edinburgh in United Kingdom, theschool with a long history of carbon cycle studies, as this university iswhere Joseph Black who discovered CO2 in 1750s was studying.
The presentations made on the first day were on the observation
results from ongoing satellite missions as well as on calibrationand validation studies of those results. There were a large numberof presentations on the results of GOSAT data retrieval and theircalibration/validation, along with the results of observations by IASI*8,
ACE*9, TES*10, as well as long-term observations of CO2 and CH4 by AIRS
and SCIAMACHY. There were presentations on comparisons among
the retrieval algorithms of researchers worldwide who work on GOSAT
spectral data to retrieve greenhouse gas concentrations as well. A study
on the vegetation activities by isolating the fluorescence producedby chlorophyll detected in the oxygen a band (0.76mm band) waspresented as new GOSAT data application study. It is a very interesting
point of view that GOSAT approaches the carbon cycle study from anaspect other than direct greenhouse gas measurement.
The presentations made on the second day were mainly on retrieval
algorithms and carbon balance studies using satellite data. It is
expected that the satellites acquire data over the areas with no existingobservational data, and thus contribute to making more accurate
estimations on where and how much greenhouse gases are emitted
and absorbed. This carbon balance study is also one of the goals for
the GOSAT Project. Topics presented this day cover the study on the
global greenhouse gas flux inversion using SCIAMACHY, GOSAT, andTES data, and a more local studies such as, an assessment of the amountof CO2 emission in metropolitan areas and power plants, by analyzing
the gap of the CO2 concentration between those largest sources ofanthropogenic CO2 emission and the neighboring areas.
The last day was dedicated for oral presentations on future satellite
missions (the related posters were presented on the second day). The
presentations included a report from the project in the process ofsatellite launch in a few years, and another report in development of asensor with the latest technology. There was a presentation on a projectthat aims to focus on the carbon flux in the tropics where there is a greatamount of uncertainty. A plan to monitor daily variation of CO2 at a
certain point using a static satellite was another topic presented this day.
The role of satellite in the carbon cycle studies is growing more andmore important. It is expected that more researchers make progress with
their research using the GOSAT data. The next workshop is scheduled in
May 2012 in the United States.

INTERVIEW

A Series : "IBUKI"'s PI Interviews­No.6

PROFESSOR

PAUL PALMER

School of GeoSciences, University of Edinburgh, UK

During the 7th International Workshop on Greenhouse Gases
Measurement from Space reported on page 3, the NIESGOSAT PROJECT NEWSLETTER interviewed the host of thisworkshop, Professor Paul Palmer of School of GeoSciences at

the University of Edinburgh. Professor Palmer is the principal
investigator (PI) for the research titled "GOSAT XCH4 andXCO2 observations: Validation and model interpretation"
selected in the GOSAT research announcement (GOSAT RA).
(Interviewer : NIES GOSAT Project Tatsuya Yokota)

Yokota (Y): Ok, I would like to start by asking you about
your personal history of research works, including youreducation and why you chose this research field.
Palmer (P): I studied physics at Bristol University for myundergraduate degree, and physics at Oxford University for
my doctorate.
Y: What was the subject of your doctorate study?
P: It was on radio occultation measurements of the Earth's
atmosphere using the Global Positioning System (GPS)satellite and a receiver in low-Earth orbit. The receivermeasured essentially the time it took for an L-band signal
to be received from the GPS transmitter. As the receiverpasses behind the atmosphere, relative to a transmitter,refraction of the signal along the atmospheric path led to adelay in the received signal, which provided very accurate
information about atmospheric temperature and humidity.
These kinds of data are now used by the numerical weather
prediction community, so that's very satisfying.
Then, I decided that I wanted to explore other things thatsatellites could do in terms of the Earth's atmosphere. So,
I went to Harvard University and spent six years working
with Professor Daniel Jacob*1. That enabled me to work on
the whole range of different subjects. Whilst at Harvard
I spent a lot of time helping to develop and interpretsatellite observations of formaldehyde to understand theemissions of isoprene*2, a biogenic hydrocarbon emitted
by broadleaf trees that also happens to be a precursor to
tropospheric ozone. Towards the end of my stay, I worked
on atmospheric CO2.
Y: You worked on many different subjects. What would you
say your interest is?
P: My interest? My interests are pretty broad. I think myspecialty is to try to connect different disciplines together.
So, for instance, my recent work I did with Anthony Bloom
in my group connected methane (CH4) with very precise
measurements of the changes in the Earth's gravitational
field. These changes can be from buildings, or from theocean or lakes. We know that the biggest single sourceof CH4 is from wetlands, which is typically seasonal. In

some places around the world, the emissions of CH4
from wetlands are determined by the variability of water.
What we managed to do was connect the change in
gravity throughout the year with changes in SCIAMACHY

CH4 columns to infer changes in emissions of CH4 fromwetlands. Connecting the dots is one thing I like to do. I

think cutting edge science in our field is progressively being
driven at the boundaries between traditional disciplines,
and this is where the action will be for the foreseeable
future.
I came to Edinburgh in 2006, and have been here ever*1­Professor Daniel Jacob­is­Vasco­McCoy­Family­Professor­of­Atmospheric­Chemistry­and­Environmental­Engineering­at­Harvard­University.

P: What we have done in Edinburgh and what othercolleagues have shown today point to the fact that GOSAT isconsistent with surface data. It is remarkable. Perhaps, it is nota huge science splash, but it is a really important step towards
gaining confidence in using satellite data to quantify CO2
fluxes. I think GOSAT has done a very good job with that.
Y: How about the GOSAT follow-on?
P: I don't know much about it. How are you going to improveupon GOSAT? Better signal to noise? Better spatial resolution?

Y: You are a member of the OCO*3 science team. How did you
meet Shamil Maksyutov's modeling group of our institute?
P: I met Shamil quite a few years ago now. I think we met
either in the OCO science team meeting or during a previous
IWGGMS. Shamil and I share many common researchinterests. As you know, we shared a British Council grant. It
helped to establish and cement relationship between the
Edinburgh, Leicester and NIES groups working on GOSAT
data. I think this relationship remains really important and

Y: We are now talking about the possibility for the next
GOSAT, including specifications and detailed objectives. So,
we have not yet decided GOSAT follow-on. There are OCO2, CarbonSat*4, and other satellites. Among them, we haveto identify what will be important in the world several years
later.
P: I am going to outline a new instrument concept tomorrow.
Instead of global coverage, this mission will focus on aregion. Broadly speaking, there are two regions with big
uncertainties in the CO2 cycle: the tropics and polar-regions,where we generally have the least number of observations.
The proposed mission will spend all this time looking at thetropics. I think that is the key thing.
Y: It is difficult and important.
P: If it weren't difficult, someone would have already done it,very useful. For instance, it helped one of my students,
Anthony Bloom, to work with Shamil during one summer right? Difficult also means a challenge and for me that alsowith a Japan Society for the Promotion of Science fellowship. makes it very exciting. And addressing challenges is often
