phenofit 0.3.2 (2021-10-15)

• Parameters of season_mov and curvefits are wrapped into options. Scripts of phenofit v2.0 will not work anymore.

• Add global options

• Growing season division was improved. Rough fitting and growing season division are separated.

• In the package dependency, plyr was replaced with dplyr.

• Add doubleLog.AG2, which allows unbalanced background value in the first half and the second half.

• Add lambda_vcurve and lambda_cv_jl to optimize Whittaker’s parameter lambda

• Add pkgdown, http://phenofit.top/.

• Growing season division was further tested on FLUXNET daily GPP estimations.

• Julia interface is ready to go, https://github.com/eco-hydro/phenofit.jl.

• phenofit script was separated into a another repository, https://github.com/eco-hydro/phenofit-scripts.

phenofit 0.3.0 (2021-06-26)

• The rough fitting result returned by [season_mov()] and [season()] was renamed from whit to fit.
• parameters of season_mov and curvefits are moved into options.

phenofit 0.2.2 (2019-03-19)

• fix visualization (plot and legend) of multiple iteration
• shinyapp works like TIMESAT now, phenofit_process and phenofit_shiny
• fix shift error of wSG, and add smooth_SG and smooth_wSG
• add weights updating function: wKong
• support asymmetric background values in spring and autumn season.

major updates

• weights of rough fitting not passed to curve fitting now
• growing season dividing is not used.

phenofit 0.2.1 (2019-03-11)

• fix point shape error of plot_input
• make_legend supports 4 quality categories (MOD13A1) and 6 quality categories (MOD09A1) now.
• wWHIT only adjusts time series of growing season.

phenofit 0.2.0 (2019-02-18)

• release in CRAN

phenofit 0.1.8 (2019-01-06)

• shiny app phenofit released.
• add QC_flag to the output of check_input.

phenofit 0.1.7 (2018-10-29)

• Add V-curve optimization in season_mov for Whittaker’s parameter lambda.
• Remove check_ylu and upper envelope in wWHIT.
• Update v-curve.

phenofit 0.1.6 (2018-10-26)

• Melt parameters (i.e. nptperyear and south) into INPUT. check_input, season, season_mov and curvefits are impacted.
• Add adj.param parameter to season, which determine whether to automatically adjust roughn curve fitting parameters.

phenofit 0.1.5 (2018-09-19)

• shiny app check_season online now.
• season can export rough curve fitting result, even no peaks or trough found.

phenofit 0.1.3 (2018-07-25)

• fix Init_param
  In previous version, parameters are only rely on “good” (w >= 0.5) values. But when “good” values in a relative low ratio, wield parameters will be generated.
  In this version, when “good” values ratio is lower than 40%, all values will be used to generate initial parameters.
  
• Export weigths of every iteration for growing season dividing function, (i.e. wHANT, sgfitw and whitsmw2). And unified their weights updating strategy.
• doubleLog.zhang is still not as stable as others.
• wTSM_cpp iter parameter is ignored now.
