We hold one of the three time-series provided by DREAM out from the inference, and utilize the other two, and occasionally also other data sets, for finding the searched parameters.
As the decomposition of the time-series provided strong indications that the trends in the number of events were not linear, generalized additive models (GAM), in the{mgcv} package [ 12], were used with the variable time as a smoother.
CHAMP vector and Ørsted scalar data dominate early in the time series, providing good global coverage.
Static, saturated areas (e.g., urban centers) are automatically filtered with a resultant time series providing a dynamic characterization of detected changes.
Streamflow time series provide baseline data for many hydrological investigations.
Mann Kendall test for the trend in the time series provided a tau coefficient of 0.6 for SST and −0.2 for precipitation, both significant at 95% confidence level.
We compared our monthly coefficient estimates of degree two with SLR and Gravity Recovery and Climate Experiment (GRACE) time series provided by the Center for Space Research CSRR) at Austin, Texas.
Landsat images time series provide an accurate spatial and temporal resolution for SL identification in floodplains, particularly in temperate zones with a good provision of cloud free images.
The correlation analysis made between displacement and piezometric time series provides a correlation coefficient greater than 85% for all the wells.
These synthetic time series provide much greater spatial detail than the 500 m gridded MODIS data, especially over more heterogeneous surfaces, which improves the efforts to characterize and monitor the spatial variation across species and communities.
Considering the latest developments in this field, great attention has been paid to data-based approaches, especially to autoregressive models; these econometric models, born in the field of finance, are usually used to analyze the vibration time series provided by the sensors applied on the monitored structures.
