Predict surface reflectance using CCDC algorithm (Zhu & Woodcock 2014)

Description

For a given Julian date, and set of CCDC coefficients, this function returns the calculated surface reflectance value using the full CCDC model described in Zhu et al 2015. Called by other functions.

Usage

ccdc_func(
  jdoy,
  coef_intp,
  coef_slp,
  coef_cos,
  coef_sin,
  coef_cos2,
  coef_sin2,
  coef_cos3,
  coef_sin3
)

Arguments

jdoy	Julian date for which to predict surface reflectance
coef_intp	Coefficient for overall values for the ith Landsat Band
coef_slp	Coefficient for inter-annual change for the ith Landsat Band
coef_cos	Coefficient for intra-annual change for the ith Landsat Band (1st harmonic)
coef_sin	Coefficient for intra-annual change for the ith Landsat Band (1st harmonic)
coef_cos2	Coefficient for intra-annual change for the ith Landsat Band (2nd harmonic)
coef_sin2	Coefficient for intra-annual change for the ith Landsat Band (2nd harmonic)
coef_cos3	Coefficient for intra-annual change for the ith Landsat Band (3rd harmonic)
coef_sin3	Coefficient for intra-annual change for the ith Landsat Band (3rd harmonic)

Value

A floating point value for the calculated surface reflectance
