This is a set of 1km images produced by Temporal Fourier analysis of ECWMF ERA5-Land total Precipitation. The imagery summarises some key environmental indicators, incorporating seasonal dynamics, for the PALE-Blu study area.
ERGO has long used a data reduction technique called Temporal Fourier Analysis on the satellite imagery [ref] datasets which provides a range of biologically interpretable variables related to levels and seasonality of temperature and vegetation indices currently for the period 2001-2019. and rainfall for 2001-2019, The TFA methods are described in detail in Scharlemann et al, 2008 and are now widely used in species distribution modelling.
The last two characters of each file name denote the output from Fourier processing:
a0 - mean
mn - minimum
mx - maximum
a1 - amplitude of annual cycle
a2 - amplitude of bi-annual cycle
a3 - amplitude of tri-annual cycle
p1 - phase of annual cycle
p2 - phase of bi-annual cycle
p3 - phase of tri-annual cycle
d1 - variance in annual cycle
d2 - variance in bi-annual cycle
d3 - variance in tri-annual cycle
da - combined variance in annual, bi-annual, and tri-annual cycles
vr - variance in raw data
