“…Here, the sensitive input data are sorted only by correlation coefficients, and for the selection this method may reject a predictor that is not very highly correlated but brings new information compared to other highly correlated predictors. So, before the selection of inputs, we use the stepwise regression method (Summers, 1985) to remove the highly correlated predictors which do not bring sufficient new information. In addition, we would like to make a cautionary note that correlation between climate input and the GRACE data does not necessarily represent causation, and in this case our (like any other similar) techniques may derive a “right answer due to the wrong reasons” but of course may fail in extrapolating well.…”

The Gravity Recovery and Climate Experiment (GRACE) mission ended its operation in October 2017, and the GRACE Follow-On mission was launched only in May 2018, leading to approximately 1 year of data gap. Given that GRACE-type observations are exclusively providing direct estimates of total water storage change (TWSC), it would be very important to bridge the gap between these two missions. Furthermore, for many climate-related applications, it is also desirable to reconstruct TWSC prior to the GRACE period. In this study, we aim at comparing different data-driven methods and identifying the more robust alternatives for predicting GRACE-like gridded TWSC during the gap and reconstructing them to 1992 using climate inputs. To this end, we first develop a methodological framework to compare different methods such as the multiple linear regression (MLR), artificial neural network (ANN), and autoregressive exogenous (ARX) approaches. Second, metrics are developed to measure the robustness of the predictions. Finally, gridded TWSC within 26 regions are predicted and reconstructed using the identified methods. Test computations suggest that the correlation of predicted TWSC maps with observed ones is more than 0.3 higher than TWSC simulated by hydrological models, at the grid scale of 1°r esolution. Furthermore, the reconstructed TWSC correctly reproduce the El Nino-Southern Oscillation (ENSO) signals. In general, while MLR does not perform best in the training process, it is more robust and could thus be a viable approach both for filling the GRACE gap and for reconstructing long-period TWSC fields globally when combined with statistical decomposition techniques.

Dissertation directed by Dr. James J. Reidy. Fermilab E769, a high statistics charm hadroproduction experiment, collected approximately 370 x 10 6 events during the fixed target run period of 1987-88. Using the Tagged Photon Spectrometer, the experiment was performed with a 250 Ge V beam of mixed hadrons (71"±, K±, p) interacting with a segmented foil target of Be, Al, Cu, and W. The use of different beam particle types and polarities allowed E769 to explore the flavor dependence of charm hadroproduction while the choice of different target materials afforded the experiment a measurement of the atomic mass dependence. Using samples of 388±31 D 0 I n° and 127±14 n*±(11"± n° I D 0) events produced from 71"± beam interactions, the shape parameters of the differential cross section distributions in fractional longitudinal momentum (x F) and in transverse momentum (Pt) were determined. The final state of D 0 in both samples is the hadronic 4-prong (K-7r+7r-7r+) decay mode. Fitting da/dxF distributions to the functional form (1-XF r yields values of n = 4.2 ± 0.5 for n° I D 0 ' and n = 2.5 ± 0. 7 for D*±. For da / dPl distributions, the fit to the functional form exp(-bP?) gives values of b = 1.00 ± 0.09 (GeV /c)-2 for D 0 I D 0 ' and b = 0.62 ± 0.10 (GeV /c)-2 for Dd. The difference inn values for the non-leading versus the leading samples of D* production are measured to be 1.7±1.4, indicative of a weak leading particle effect. Finally, the asymmetry for leading versus non-leading D*'s was determined to be 0.20±0.14. 5.2 Number of n° and n* events per P? bin.

“…This position was then adjusted according to the known shower shapes. A stepwise regression fit [33] was used to merge the insignificant sectors into more significant ones. The transverse energy distribution of each sector was fit to a known electromagnetic shower shape plus a broader version of this shape used to approximate a hadronic shower.…”
