Harmonic Baseline Experiments

This dataset accompanies a study of harmonic baseline model parameterization for forest condition monitoring. 

These rasters represent a series of experiments testing the impact of changing the following parameters on condition score estimates for the Landsat scenes intersecting Massachusetts, Rhode Island, and Connecticut:

Spectral transforms:

• Tasseled Cap Greenness (TCG)
• Normalized Difference Vegetation Index (NDVI)
• Simple Ratio (SR)
• Enhanced Vegetation Index (EVI)

Baseline period:

• 2000-2010
• 2005-2015

Harmonic frequencies:

• 1/365.25, 2/365.25 (h12)
• 1/365.25, 3/365.25 (h13)

Time series image inputs:

• All available observations (full)
• Single-sensor (16d)

All results are for the year 2017 and we have also included the 2017 assessment produced as part of our "reanalysis" study for comparison.
