Title: Available Light Within the Water Column and on the Seafloor of Arctic Fjords
Type: Package
Description: Satellite data collected between 2003 and 2022, in conjunction with gridded bathymetric data (50-150 m resolution), are used to estimate the irradiance reaching the bottom of a series of representative EU Arctic fjords. An Earth System Science Data (ESSD) manuscript, Schlegel et al. (2024), provides a detailed explanation of the methodology.

Download fjord PAR data as NetCDF files.

Description

This functions queries the FTP server where the NetCDF files are stored. It will retrieve the one file that matches the name provided to it via the fjord argument. Note that these files can be multiple gigabytes in size.

Usage

Usage

fl_LoadFjord(
  fjord,
  layer = "PAR_B",
  dirdata = NULL,
  TS = FALSE,
  verbose = FALSE
)

Arguments

fjord

Expects a character vector for one of the 8 available fjords. See fl_ListFjords for the list of possible choices.

layer

The layer of data the user wants to load. The default "PAR_B" will load monthly bottom PAR data.

Extract monthly K_PAR data from a NetCDF file downloaded by FjordLight.

Description

This functions will extract the monthly K_PAR data stored within a K_PAR NetCDF file downloaded via fl_DownloadFjord. Note that these data are very large. If one would prefer to work with the smaller annual or monthly climatology values, instead use flget_climatology. There are options for how the user would like to subset the data, which data format the data should be extracted to, and if the user would like to plot the data in the process.

Usage

flget_KPARMonthlyTS(
  fjord,
  month = NULL,
  year = NULL,
  mode = "raster",
  PLOT = FALSE
)

Arguments

Expects the object loaded via fl_LoadFjord. NB: when loading the data one must set the argument fl_LoadFjord(..., TS = TRUE). See examples below.

month

The monthly values to extract. Accepts one or many integer values from 3 to 10. If no values are provided, the default value of NULL will be passed to the function, telling it to load all available months of data (i.e. 3:10). This is used in combination with year to determine which monthly data to extract.

year

The years of data to extract. Currently accepts one or many integer values from 2003 to 2022. If no values are provided, the default value of NULL will be passed to the function, telling it to load all available years of data (i.e. currently 2003:2022). This is used in combination with month to determine which monthly data to extract.

mode

Determines the format of the data loaded into the R environment. The default "raster" will load the data as a raster format. The other option "df" will load the data as a data.frame with three columns.

PLOT

Boolean argument (default = FALSE) that tells the function if the user would like the loaded data to be plotted or not.

Value

Depending on which arguments the user chooses, this function will return the chosen monthly K_PAR data as a RasterStack (mode = "raster") or data.frame (mode = "df"). The data.frame will contain the following columns:

longitude

Extract p function data from a NetCDF file downloaded by FjordLight.

Description

This functions will conveniently extract the p function data stored within a NetCDF file downloaded via fl_DownloadFjord. There are options for how the user would like to subset the data, which data format the data should be extracted to, and if the user would like to plot the data in the process.

Usage

flget_Pfunction(
  fjord,
  type = "coastal",
  period = "Global",
  month = NULL,
  year = NULL,
  mode = "function",
  PLOT = FALSE,
  add = FALSE,
  ...
)

Arguments

fjord

Expects the object loaded via fl_LoadFjord.

type

Whether the p function should show values for the coastal zone (< 200 m deep), or the shallow zone (< 50 m deep).

period

Here the user determines which time period of data should be loaded. To load the total average values (default) use "Global". One may chose instead to load the "Yearly" or "Monthly" values. Note that monthly values here represent the climatological average for the month, not one month in a given year. If the user would like one specific month of data (only available for bottom PAR), they should use flget_PARbottomMonthlyTS.

month

The monthly climatology to extract. Accepts an integer value from 3 to 10. This argument is ignored if period = "Yearly".

year

The yearly average to extract. Currently accepts an integer value from 2003 to 2022. This argument is ignored if period = "Monthly".

mode

Determines the basic process that this function performs. The default mode = "function" will allow the user to create a function that they can then use themselves to determine p curves using their own input (see examples). Or to access the underlying p function data directly set mode = "df".

PLOT

Boolean argument (default = FALSE) that tells the function if the user would like the loaded data to be plotted or not.

add

Boolean (i.e. TRUE/FALSE) to tell the function to add the p function plot to an existing plot. See examples below.

...

Additional arguments that may be passed to flplot_Pfunction, which will implement them using base R plotting functionality.

Value

Depending on which arguments the user chooses for mode, a function will be returned (see examples). Or a two column data.frame:

irradianceLevel

A threshold value [mol photons m-2 d-1]

optics_global|year|month

The column name is determined by the arguments passed to optics and either global, year, or month, depending on which period was indicated. These values show the percent of the fjord (filtered for pixels with a depth of 200 m or shallower) that received at least the amount of irradiance indicated in the irradianceLevel column.
