Joint analysis of selected GRACE monthly spherical harmonic solutions and monthly MASCON solutions
نویسندگان
چکیده
Study presented in this paper is focused on comparison and statistical assessment of differences between the selected Level 2 products satellite mission Gravity Recovery Climate Experiment (GRACE). Global monthly gravity field models terms spherical harmonic coefficients produced by three institutes GRACE Science Data System are compared with partially independent MASCON global model. Detailed analysis performed 5 river basins: Amazon, Congo, Danube, Yenisei Lena. For each solution, 8 different filtrations available at International Center for Field Models (ICGEM) tested over time span from April 2002 to July 2016. Fischer test two significance levels 10% 5% has been order qualify particular solutions.

Uncertainty Analysis of Monthly Streamflow Forecasting
Streamflow forecasting is an important factor in water resources planning and management. In this study Feed Forward Artificial Neural Network (FFANN) was used for monthly streamflow forecasting. Three scenarios were considered for modeling. Principal Component Analysis (PCA) is used for reducing the model architecture complexity and input data reduction. Twelve statistical criteria were used t...
متن کاملModeling and prediction of time-series of monthly copper prices
One of the main tasks to analyze and design a mining system is predicting the behavior exhibited by prices in the future. In this paper, the applications of different prediction methods are evaluated in econometrics and financial management fields, such as ARIMA, TGARCH, and stochastic differential equations, for the time-series of monthly copper prices. Moreover, the performance of these metho...
متن کاملImproved accuracy of GRACE gravity solutions through empirical orthogonal function filtering of spherical harmonics
[1] One of the major problems one has to deal with when working with Gravity Recovery and Climate Experiment (GRACE) data is the increasing error spectrum at higher degrees in the provided Stokes coefficients, appearing as unphysical North-South striping patterns in the maps of equivalent water height (EWH). This phenomenon is commonly suppressed by application of a Gaussian smoothing filter, w...

Many of us have been watching the Olympics this week (how about that Phelps?). The first week culminated with an exciting individual women’s gymnastics competition. Despite the home advantage (see Balmer and Nevill, 2003 in the annotated bibliography), Americans Nastia Liukin and Shawn Johnson took Gold and Silver respectively (63.325 and 62.725), with Chinese Yilin Yang winning Bronze (62.650)...
