pr_fm_phenocam: Format PhenoCam data

In bluegreen-labs/phenor: An R phenology Modelling Framework

Format PhenoCam data

Description

Preprocessing of all PhenoCam data into a format which can be ingested by the optimization routines etc. the original nested list is flattened for speed.

Usage

pr_fm_phenocam(
  path = tempdir(),
  direction = "rising",
  gcc_value = "gcc_90",
  threshold = 50,
  offset = 264,
  spread = 30,
  internal = TRUE
)

Arguments

path	a path to 1 or 3-day PhenoCam transition date estimates (no validation checks will be done, so mixed files will lead to mixed or duplicated results!)
direction	The phenophase considered, "rising" for spring and "falling" for autumn. When using fall the offset should be 365. (default = rising)
gcc_value	The gcc time series from which the phenophase estimates were derived either (default = gcc_90)
threshold	Threshold ( the phenophases (10, 25, 50) (default = 50)
offset	offset of the time series in DOY (default = 264, sept 21)
spread	maximum distance between CI of phenophase (default = 30) increase this value to include more uncertain phenophase estimates
internal	return data as structured list to R workspace or write to RDS file (default = TRUE)

Details

In addition to the normal transition dates the offset in julian days to the previous phenophase is included as transition_dates_prior.

Examples

# run with default settings
# looks for transition date files derived
# through phenocamr in your home directory
# change the path to match your setup
## Not run: 
phenocam_data = pr_fm_phenocam()

## End(Not run)
