With the established model the empirical research has a good performance in testing the predictive effects on four different time series indices.
The inclusion of an estimated time-series index of areal soil moisture status into the calibration procedure, however, significantly reduced the number of feasible parameter combinations, and resulted in predictions that confirmed Bowen ratio measurements of actual evapotranspiration.
Sea surface temperature 4 (SST4, also known as, El Niño 4 index) time series, an index for ENSO, a global climatic phenomena associated with extreme weather in Central America was obtained from the United States National Oceanic and Atmospheric Administration Climate Prediction Center (http://www.cpc.ncep.noaa.gov/data/indices/ersst3b.nino.mth.81-10.ascii).
The second types of methods are time series method, index analysis, and factor analysis.
The time series of index values at a location, derived from calibrated imagery, represents a consistent surrogate to track density changes.
Time series vegetation disturbance index results indicate that in Guna-Tana watershed, since 2001, vegetation disturbance index values were at range of natural variability.
A procedure similar to that for ( {C}_T^2 ) is used to estimate the refractive index structure function parameter ( {C}_n^2 ), hereafter denoted as ( {C}_{n,mathrm{U}mathrm{A}mathrm{V}}^2 ) using the time series of refractive index n: {C}_{n,mathrm{U}mathrm{A}mathrm{V}}^2={c}_n/left 0.0730846{U}^{2/3}right) (9).
A time series of the index is shown in Figure 3, below.
Some basic types of stochastic processes include Markov processes, Poisson processes (such as radioactive decay), and time series, with the index variable referring to time.
Both the option and time series data on index options were employed for the calibration.
Tables 4, 5, 6, 7, 8, 9 and 10 tabulate the time series of each index for each country.
