We have just released a new climatology of temperature and salinity for the Indian Ocean. This climatology improves on the World Ocean Atlas 2009 (WOA) in the Indian Exclusive Economic Zone and the rest of the Bay of Bengal. Annual, seasonal, and monthly climatologies of temperature and salinity are available in two sets of files. The first set is for only the Indian Ocean, while the second set merges the new climatologies with WOA to produce merged global climatologies. In addition, we have

A feed-forward neural network is used to create a monthly climatology of the sea surface fugacity of CO2 (fCO2) on a 1° × 1° spatial resolution. Using 127 880 data points from 1990 to 2011 in the track-gridded database of the Surface Ocean CO2 Atlas version 2.0 (Bakker et al.), the model yields a global mean fCO2 increase rate of 1.50 μatm yr−1. The rate was used to normalize multiple years fCO2 observations to the reference year of 2000. A total of 73 265 data points from the normalized data were used to model the global fCO2 climatology. The model simulates monthly fCO2 distributions that agree well with observations and yields an anthropogenic CO2 update of −1.9 to −2.3 PgC yr−1. The range reflects the uncertainty related to using different wind products for the flux calculation. This estimate is in good agreement with the recently derived best estimate by Wanninkhof et al. The model product benefits from a finer spatial resolution compared to the product of Lamont-Doherty Earth ...

In general, I am a fan of the Berkeley Earth approach for reconstructing past temperature variations - particularly because they present their data in an open user-friendly manner which should have long ago been adopted by some of the other groups. Mathematically the approach they use is fairly solid which allows for a higher spatial and temporal resolution of the end product. However, there are a few concerns that I have - maybe not as strong as to say concerns - but perhaps questions is a better word.. [1] Approach - I believe they create a baseline climatology as a function of lat, long, elev for all land areas using what looks like a form of spline - Anuspline - a program for interpolating temperatures uses a similar approach. The residual from the climatology surface is then kriged and re-added to the climatology. They then subtract the baseline climatology for every station and krige the anomalies back through time. Once anomalies are spatially and temporally kriged they re-add the surface ...

The Climatology, Hydrology and Paleo-Environmental Lab (CHAPEL) was started in January, 2017. Research in CHAPEL is focused on North American climatology and hydrology of the past 2000 years, the present and the near future. Our goal is a better comprehension of decadal-to-centennial climate variability, just beyond the scale of instrumental records, yet vital for our understanding of regional climate and hydrology, anthropogenic global warming impacts, and water management for infrequent extremes, such as sustained droughts and floods.. We use a wide variety of methods and approaches. For paleoclimate and paleo-hydrology reconstructions, we use tree-rings, pollen preserved in lake sediments, and other biological and physical proxies from lake sediments (i.e., diatom and varved sediment analysis). Research tools that we use for modern and near-future projected climatology and hydrology include: instrumental climatological and hydrological databases and archived GCM and RCM runs. Our research is ...
A. HadCRUT3 is an anomalies dataset, and all the uncertainties apply to the anomalies. If you are interested in year-to-year changes its best to use the anomalies if you can. So before you start using the actuals, think hard to check you cant use the anomalies instead. We can make actuals - we merge the SST climatology from the HadSST2 dataset and the land climatology from CRU high resolution dataset (New et al 2002 - see http://www.cru.uea.ac.uk/cru/data/hrg.htm), to make a climatology for HadCRUT3 and add this to the anomalies dataset. But this has two problems: it adds an additional source of uncertainties which we dont allow for, so our uncertainty analysis is no longer valid; also land surface actuals vary over short distances because of large changes in altitude: so the actual range of temperatures in a 5 degree grid box can be large, and the mean value is not always useful. The absolute global-average annual temperature and the absolute hemisphere-average annual temperatures for ...
Project Lead: Amanda Tan, Department of Oceanography, University of Washington eScience Liaisons: Rob Fatland, Anthony Arendt. A dynamic information framework (DIF) is a decision support structure centered on earth system science models and data resources used to address policy challenges in water resources caused by population growth, socio-economic development and climate change, particularly in developing nations. This decision support tool is particularly useful in developing nations because such a framework encourages open data sources, transparency and also, by putting such a framework in the cloud, it eliminates the need for standalone infrastructure.. The AralDIF project aims to inform policy challenges in water resources in the Aral Sea Basin; bridging the information gap between decision makers and scientists. The goal of this project is to better inform policy challenges in the area by providing a scalable and flexible framework for data storage and tools for data visualization and ...

El Niño-Southern Oscillation (ENSO) is a global coupled ocean-atmosphere phenomenon. The Pacific Ocean signatures, El Niño and La Niña are important temperature fluctuations in surface waters of the tropical Eastern Pacific Ocean. The name El Niño, from the Spanish for "the little boy", refers to the Christ child, because the phenomenon is usually noticed around Christmas time in the Pacific Ocean off the west coast of South America.[5] La Niña means "the little girl".[6] Their effect on climate in the subtropics and the tropics are profound. The atmospheric signature, the Southern Oscillation (SO) reflects the monthly or seasonal fluctuations in the air pressure difference between Tahiti and Darwin. The most recent occurrence of El Niño started in September 2006[7] and lasted until early 2007.[8]. ENSO is a set of interacting parts of a single global system of coupled ocean-atmosphere climate fluctuations that come about as a consequence of oceanic and atmospheric circulation. ENSO is the ...

Thats the word from Australian scientist William de la Mare, who studied more than 40,000 records of whaling kills in an attempt to fill in the blanks about the ice. His theory was that while ships never left the water, they hunted close to the ice, where whales found the most food. Therefore, ship positions indicated the position of the ice edge. And since the whaling records began in 1931, they would reveal the decade to decade shifts in ice.. Writing in Nature (Sept. 4, 1997, pp. 57-60, see also pp. 20-21), de la Mare, whos with the Australian Antarctica Division of the Department of Environment, Sport and Territories, found that the edge of the summer ice moved almost 3 degrees south between the mid-1950s and early 1970s.. Thats a big shift -- almost 200 miles -- enough to reduce the area of the sea ice by 25 percent.. Does de la Mares finding signals an increase in planetary temperature? Perhaps, but even though scientists have recently reported disturbing shrinkage of glacial ice in ...

Abstract. Three global Chemistry Transport Models - MOZART, MOCAGE, and TM5 - as well as MOZART coupled to the IFS meteorological model including assimilation of ozone (O3) and carbon monoxide (CO) satellite column retrievals, have been compared to surface measurements and MOZAIC vertical profiles in the troposphere over Western/Central Europe for summer 2003. The models reproduce the meteorological features and enhancement of pollution during the period 2-14 August, but not fully the ozone and CO mixing ratios measured during that episode. Modified normalised mean biases are around −25% (except ~5% for MOCAGE) in the case of ozone and from −80% to −30% for CO in the boundary layer above Frankfurt. The coupling and assimilation of CO columns from MOPITT overcomes some of the deficiencies in the treatment of transport, chemistry and emissions in MOZART, reducing the negative biases to around 20%. The high reactivity and small dry deposition velocities in MOCAGE seem to be responsible for ...
Meteorological model output fields are interpolated to terrain following coordinate system. Resolution is the same as the native coordinate system. Your local terrain will not match model terrain, which is much smoother. In very complex terrain the model is probably not very accurate unless local wind flow is being driven by the large-scale synoptic conditions - strong winds.. Roland Draxler. ...

New high throughput experimental techniques have turned the life sciences into a data-intensive field. Scientists are faced with new types of problems, such as managing voluminous sources of information, integrating heterogeneous data, and applying the proper analysis algorithms; all to end up with reliable conclusions. These challenges call for an infrastructure of algorithms and technologies to supply researchers with the tools and methods necessary to maximize the usefulness of the data. eScience has emerged as a promising technology to take on these challenges, and denotes integrated science carried out in highly distributed network environments, or science that makes use of large data sets and requires high performance computing resources.. In this thesis I present standards, exchange formats, algorithms, and software implementations for empowering researchers in the life sciences with the tools of eScience. The work is centered around Bioclipse - an extensible workbench developed in the ...
Rob Procter, Alex Voss, Peter Halfpenny, Marzieh Asgari-Targhi; National Centre for e-Social Science. As part of a study to investigate and tackle barriers to adoption of e-Infrastructure, we have been conducting a review of project documentation, reports and academic papers in the field with the aim of establishing a typology of barriers to uptake and candidate responses to tackle them. Underlying this is the expectation that there are ways of dimensioning the problem space so as to reveal recurring patterns in adoption processes; that these barriers will be "typical" in a number of different ways, e.g., typical in a particular domain, for a given technology, for specific stakeholders, etc. Of course, the real value of this study lies in how it may prospectively afford the adoption of e-Infrastructure rather than simply explain its history. The concern here is how to make our findings re-usable by a broad range of e-Infrastructure users, both current and future. What is needed is a format that ...

The present work investigates dry-friction whip and whirl phenomena for a rigid rotor contacting at two bearing locations. The idea originated with a paper by Clark (2009, "Investigation of the NRG #40 Anemometer Slowdown," American Wind Energy Association, Windpower 2009, Chicago, IL, pp. 1-16) on an anemometer undergoing dry-friction whip and whirl. The anemometer rotor was supported by two Teflon® bushings within an elastically supported housing. The dry-friction forces arose at the bushings. Prior models for dry friction whirl and whip have considered rub at one nonsupport location. The present analytical model consists of a rigid rotor connected to a rigid stator at two rubbing-contact locations. Analytical solutions are developed for the following normal reaction forces at the contact locations: (1) In phase, and (2) 180° out of phase. Analytical solutions are only possible for the same radius-to-clearance ratio (RCl) at the two rub locations and define regions where dry-friction whirl ...
In this paper, we consider a sequential monitoring procedure for detecting changes in copula function. We propose a cusum type of monitoring test based on the empirical copula function and apply it to the detection of the distributional changes in copula function. We investigate the asymptotic properties of the stopping time and show that under regularity conditions, its limiting null distribution is the same as the sup of Kiefer process. Moreover, we utilize the bootstrap method in order to obtain the limiting distribution. A simulation study and a real data analysis are conducted to evaluate our test.
We study the impact of certain transformations within the class of Archimedean copulas. We give some admissibility conditions for these transformations, and define some equivalence classes for both transformations and generators of Archimedean copulas. We extend the r-fold composition of the diagonal section of a copula, from r ∈ N to r ∈ R. This extension, coupled with results on equivalence classes, gives us new expressions of transformations and generators. Estimators deriving directly from these expressions are proposed and their convergence is investigated. We provide confidence bands for the estimated generators. Numerical illustrations show the empirical performance of these estimators. ...
