time-series analysisagricultureHarmonic analysis of a nine-year time series of NOAA AVHRR Normalized Difference Vegetation Index (NDVI) data was used to develop an innovative technique for land use/land cover identification based on temporal changes in NDVI values. Different land cover types exhibit ...
This algorithm allows the user to perform a specific analysis of a given scalar time series. As a result, we obtain a functional model made of (1) a trend component, (2) a linear combination of Fourier terms, and (3) the so-called mixed secular terms by reducing the computation time ...

Varved sequences represent imperfect metorologic time series that lend themselves to harmonic analysis. Both Fourier (amplitude) and power (variance) spectrum analyses have been used in the study of several varve types; the first for maximum resolving power and the second for stability and the stud...
In recent decades, researchers have developed methods and models to reconstruct time series of irregularly spaced observations from satellite remote sensing, among which the widely used Harmonic Analysis of Time Series (HANTS) method. Many studies based on time series reconstructed with HANTS documented...
This repository is a python implementation of the Harmonic ANalysis of Time Series (HANTS) applied to geospatial data. The python module can be used to perform the HANTS algorithm to a collection of time-variable raster data at each pixel. ...
Harmonic analysis is a wellspring of ideas and applicability in mathematics, engineering, and the sciences that has flourished, evolved, and deepened with continued research and exploration. The ANHA series reflects the intricate and fundamental relationship between harmonic analysis and general disciplines...

Analysis of the temporal and spatial changes of ecological environment quality using the optimization remote sensing ecological index in the middle Yellow ... We reconstructed data from 19862023 Landsat series images using the harmonic analysis of time series (HANTS) algorithm on the Google Earth Engin...
With the increasing proliferation of non-linear loads, more harmonics are expected to be injected into the distribution system. This paper presents time series simulations of harmonic analysis in the distribution system. Modeling and analysis approach is used to perform the time series of harmonic ana...
