eco-hydro/phenofit: phenofit v0.3.3 (2021-12-11)

phenofit passed test in multi-GS regions

• Fix typo error in curvefits' document.

• Fix the error of plot.fFITs, due to fFIT renamed to model.

• Rename function opt_season to season_input

• In the case of none growing season division information, find_season.peaks will be error. Fixed now.

• Fix the bug of init_param in the approximately monotonous time-sereis (e.g. fast harvest leads to a very short senescence period, and hence approximately monotonic in the whole growing season). In previous version, the parameter boundary of sos might exceed that of eos.

• Improved the phenology extraction method PhenoTrs, PhenoDeriv and PhenoGu in the approximately monotonous time-sereis. In the previous version NA value will be return. In the current version, if the time series is monotonously increasing, EOS will be the mean value of t[n] and peak date of season (POP). But PhenoKlos has no method to avoid NA values, because it used the strict mathematical solution to find the extreme values in the curve of curvature's change rate.

MAJOR updates to improve multi-GS phenology extraction

• Fix the bug of findpeaks, which lead to sharp changed growing season failed to detect.

• Fix the bug of PhenoKlos, where minpeakheight not work in previous version.

• Fix the bug of check_season_dt, where peak might be able to greater than end.

• Remove the parameter check_season_dt in removeClosedExtreme, which might eliminate good extreme values.

• add get_pheno.rfit to extract vegetation phenology from rough fitting directly.
