 Okay, so thank you for inviting me here and also giving the connection of another research focus within Cliver which is called the consistency between planetary energy balance and ocean heat storage. And I will give you an introduction on the general idea and also to have the opportunity later on doing and also on the end of this week, not to discuss what can be put together. So under an equilibrium climate, the amount of incoming and outcoming energy is balanced and the earth energy budget is on a balanced conditions. And if there is any climate forcing, this energy balance will be not a balanced anymore so there will be a positive or negative earth energy imbalance. And under the current climate change conditions we measure a positive earth energy imbalance of the amount of 05 to 1 watt per meter square. And this accumulated energy in the climate system is stored by the earth's surface and the majority of this energy is stored within the global oceans. So there are different symptoms of this accumulation of energy in the climate system and this differentiating between source and symptoms will also our argumentations why we see for example the measure of global surface temperature is not the one which might be the most robust one for discussing climate variability and climate change issues. So the symptoms of these accumulated energies include for example the rise of global surface temperature also the rise in ocean heat content, the rise in sea level and so on. There are different aspects here from where you're all aware of. And so how we can measure this earth energy imbalance for actually there are different methods in describing this or estimating this. And there's first the radiation at the top of the atmosphere by a system of satellites. There's the surface fluxes which is the sum of the different fluxes within the of the surface energy budget. And there's a part of the energy which is stored in the climate system predominantly by the ocean heat content estimate and also by the hint cast for example the ocean and atmospheric career analysis and the climate protections. So I will just give some insight on results for sorry for the radiation at the top and the endist ocean inventory. And there's a comparison here of time series from series. This is a system of satellites which gives you the radiation from the top of the atmosphere directly the net flux and the comparison with ocean heat content estimates from different groups. And you can clearly see the result here and why we have created one of those groups is that there are still large discrepancies in these estimates although they should give up the same result. And in particular also if you look for the different heat content estimates that you have still different results. So the top of the atmosphere should more or less match the result for ocean heat content and there are still issues where we call this term of missing energy in the climate system. And another point is that we are first currently estimations in the range of which is also marked as the last IPCC between 05 and 1 watt per meter square and which is still not yet precise enough in terms of resolving all the issues for climate forcing for example also the volcanic. So this is the result for the storage part for the ocean heat content estimate. This is the time series for different depth layers from an ocean reanalysis system. And I just wanted to highlight here the problematics shortly that you have a kind of differentiating between the measurements for the historical measurements period which has a large development in terms of sampling within the ocean and from really limited to terms of system technologies and there was a huge increase with the new, let's say, modern global ocean observing system which has increased in particular with the Argo observing system and hence a large increase in the sampling of the global ocean. But still, so this is the result. If you see here the result between the sampling before these are the estimates directly from ocean heat content from different groups. You can see that there are large differences between those estimates. I do not have time to go into detail here why are there. But of course one of the largest region is the sampling issue and you can see the improvement here if you go to the area, error of Argo where we have a more complete observing system. But if you have a focus on the area of the focus on the Argo error you can clearly see that there are still also large issues which are not in the position that we need for observing climate variability and climate change. So I just summarized here and I do not have time to go into the other issues but we have summarized here in one paper which we have developed under this research focus and we define here that we need a precision of 0.1 per meter square to scale time scales and 0.5 on sub annual to inter annual time scales. We can say that the system of satellite observation at the top of the atmosphere is the most precise for describing the changes in time. The most precise one and with the most biggest future we could have is the estimate of ocean heat content for the absolute measure of energy imbalance but still there are issues to be solved. There are large still uncertainties but there will be a visual the new way would be to go to the regional budget constraint for the surface budget and that we have the tool of climate models and re-analysis systems to get more insight in the processes and have the connection then here with the climate variability. So still again there are large uncertainties then there is a long accounting where the heat is going and of course that we have to improve our knowledge on the observational capability and to bring the communities together in order to improve the things we have already and that we can forward. So the goal then finally of the biggest objective of concept heat is that you create a synergy community which is all concerned with the flow of energy through the climate system and these include communities for the atmospheric radiation ocean heat content, surface fluxes, climate variability and change data assimilation, operational services, the climate projection and the global sea levels. So going to all the climate observational tools for remote sensing and pseudo data, re-analysis system and numerical models including the climate model systems. So the main big issue is to concentrate on the Earth energy imbalance the ocean heat budget and the atmosphere ocean turbulent and relative fluxes the observational uncertainties and the variability for a range of time and space scales and to analyze the consistency between the satellite base planetary heat balance and ocean heat storage estimate by using the different products and the different data and climate and tools. We have already defined within the community different key questions which would guide our activities. These include what is the magnitude and the uncertainties of our estimates of the Earth energy imbalance and how does it vary over time. Can consistency between planetary heat balance and ocean heat storage achieved and what are the major limitations? How are top of the atmosphere, natural radiation and ocean heating rate distributed in space and time? This is one of the big issues which might also be in cross cutting with this research focus here. How can we improve validation requirements for and from climate models to improve estimates of the Earth energy imbalance and how can we better constrain the surface energy fluxes and the spatial temporal variations at regional scales. So we had already some activities. There was one joint ESA Clive workshop in 2013. We had predominity going out to the concept of cages. I'm sorry, this was one of my first workshops to be organized. I forgot to make a picture, so don't miss a picture today. And the outcome of this workshop is a project which is still ongoing. It's the Ocean Heat Flux. There's another, sorry, Heat Flux project. Then we had another smaller project which was the creation of an international working group at the International Space Size Institute. And the outcome was a prospective paper which is now a sector in climate change on the consistency of intricate observing systems, monitoring the energy flows in the Earth system. We're nominating that the Earth energy imbalance is the most practical way in estimating climate variability and climate change. Then we had very good discussions during the Pan-Clive our meeting, especially there was a breakout session in July 2014 and we had several side discussions and smaller groups which were really effective. I would have liked to have several pictures of those. The development of key scientific questions was one of the outcomes and basis for the development of the concept white paper which you can find online on our web page. Then we had just one month ago another workshop. This was the first concept heat workshop and took place at the mid-office in Exeter and I've tried to summarize quickly more or less the outcomes of this workshop. So again we are coming to the Earth energy imbalance as the fundamental metric or the central of the search focus. There are findings going to that you have to estimate Earth energy imbalance more locally to also to put the communities together because with those budget applications in terms of inferring this from different methods through physical budget constraints to the top of the atmosphere flux and atmospheric energy transport, ocean transport, divergence and changes in ocean heat content and directly computing the RC fluxes this would bring new insights and push the communities together. The other point is, oh sorry, to go the estimation of ocean heat content plays a key role of climate science because it's the most practical way in terms of estimating the absolute value for the Earth energy imbalance but as you've seen there are still some issues to be solved to improve the ocean current ocean observing system and also to improve the estimates of the capacity from the observing system and to go to the studies of energy flows in the climate models, modes, sorry so which is also one pressing point with this activity here is to go to the vertical disposition of heat in the ocean and the horizontal redistribution of heat in the ocean in climate modes, also the hiatus but also Pacific Decadal Oscillation and so on. And one of our big results is that we are about to develop a recommendation letter several recommendation letters to different research and operation institutions and we are working on a web page currently our web page is integrated with SincLiber but it should become a cross-cutting point for the different communities for the summer schools and for studying to conference sessions. So I'm already in the end now I'm just like coming back the same figure as shown by Yuna Shan this morning and again to show here that this is implemented in the clever organization and also that it has its very cross-cutting issues and to go to the connection between those two is I think different talks for example have shown this morning that there is a need of having more precise metrics for climate variability and change studies so we propose here the earth energy imbalance and we propose here a multidisciplinary community behind this to give those studies and information and expertise exchange and I think there are several common lines within this research focus and it's good to have this connection here and the discussion during the work up thank you very much.
