New research finds ocean's most abundant organisms have clear daily cycles（图）
The ocean Microbes Water The deep sea Bacteria Ocean currents
2014/7/18
Imagine the open ocean as a microbial megacity, teeming with life too small to be seen. In every drop of water, hundreds of types of bacteria can be found. Now scientists have discovered that communi...

The Allen Telescope Array Pi GHz Sky Survey II. Daily and Monthly Monitoring for Transients and Variability in the Bootes Field
Monthly Monitoring Transients Variability Bootes Field
2011/9/29
We present results from daily radio continuum observations of the Bootes field as part of the Pi GHz Sky Survey (PiGSS). These results are part of a systematic and unbiased campaign to characterize va...
Bayesian trend analysis for daily rainfall series of Barcelona
Bayesian trend analysis daily rainfall series of Barcelona
2010/9/10
A Point-Over-Threshold approach using a reparameterization of the Generalized Pareto Distribution (GPD) has been used to assess changes in the daily rainfall Barcelona series (1854–2006). A Bayesian a...
Role of oxidative stress in seasonal and daily vertical migration of three krill species in the Gulf of California
Role of oxidative stress seasonal
2014/4/17
Vertical distribution and abundance of three numerically dominant krill species (Nyctiphanes simplex,
Nematoscelis difficilis, and Euphausia eximia) were surveyed in the Gulf of California to underst...
Adequate knowledge of the nature of river flow process is crucial for proper planning and management of our water resources and environment. This study attempts to detect the salient characteristics o...
Diagnostic statistics of daily rainfall variability in an evolving climate
daily rainfall evolving climate
2010/1/27
To investigate the character of daily rainfall variability under present and future climate described via global warming a suite of diagnostic statistics was used. The rainfall was modeled as a stocha...
The level crossing analysis of German stock market index (DAX) and daily oil price time series
German stock market index daily oil price time series
2010/4/27
The level crossing analysis of DAX and oil price time series are given. We determine the average frequency of positive-slope crossings, $\nu_{\alpha}^+$, where $T_{\alpha} =1/\nu_{\alpha}^+ $ is the a...

Actual daily evapotranspiration MERIS AATSR data Chinese Loess Plateau
2010/2/1
The Chinese Loess Plateau is located in the north of China and has a significant impact on the climate and ecosystem evolvement over the East Asian continent. Estimates of evapotranspiration (ET) at a...
Testing the performance of three nonlinear methods of time seriesanalysis for prediction and downscaling of European daily temperatures
nonlinear methods time seriesanalysis European daily temperatures
2009/11/11
We investigated the usability of the method of local linear models (LLM), multilayer perceptron neural network (MLP NN) and radial basis function neural network (RBF NN) for the construction of tempor...
Long-term predictability of mean daily temperature data
Long-term predictability mean daily temperature data
2009/11/9
We quantify the long-term predictability of global mean daily temperature data by means of the Rényi entropy of second order K2. We are interested in the yearly amplitude fluctuations of the temperatu...
Complexity and predictability of daily precipitation in a semi-arid region:an application to Ceará,Brazil
Complexity predictability daily precipitation semi-arid region
2009/11/9
Complexity and predictability of daily precipitation in a tropical semi-arid region (Ceará State, Brazil) is assessed by applying entropy concepts. Precipitation regimes in that region depend on sever...
Nonlinear correlations of daily temperature records over land
Nonlinear correlations daily temperature records
2009/11/9
We present a near global statistics on the correlation properties of daily temperature records. Data from terrestrial meteorological stations in the Global Daily Climatology Network are analyzed by me...
