THE APPLICATION OF HILBERT-HUANG TRANSFORM TO NON-STATIONARY ENVIRONMENTAL DATA SETS
Milan Hofreiter · 2010
The paper devotes analysis of environmental data sets by using Hilbert-Huang transform (HHT). The environmental data were measured by meteorological stations which are deployed in the southern part of Czech Republic. The analysis is performed in both the time and frequency domains. The aim of the work is to investigate selected measured non-stationary time series by using the HHT method and also provide more physically meaningful interpretation of underlying non-linear dynamic systems. The results can help better describe dynamic characteristic of ecosystems.
