nr 19

In the paper a flood phenomenon is analyzed. For this purpose data from GRACE satellites (Gravity Recovery and Climate Experiment) was used. Filtered data presented in a form of millimeters of Equivalent Water Thickness (EWT) was interpolated in places where flood in 2010 had happened (south of Poland). On a basis of graph where time series of EWT were presented, some conclusions were made. For the thesis confirmation meteorological WGHM and hydrological NOAA models were added to the GRACE model.

nr 19

In the paper an Equivalent Water Thickness (EWT) determination as a way of observing gravity variations is described. Since raw data acquired directly from Gravity Recovery and Climate Experiment – GRACE satellites is unsuitable for analysis due to stripes occurrence, a filtering algorithm must be used. In this paper, authors are testing two isotropic (Gauss, CNES/GRGS) filters and two anisotropic filters (Wiener-Kolomogorov, ANS). Correlation, amplitude ratio, and modification were determined as well as maps were generated.
