summarise_inputs: Summarize Inputs over Common Timeseries

In cvoter/isoH2Obudget: Lake Water Budget Using Stable Isotopes

Description

This function takes raw weather, lake surface temperature, isotope, lake level, groundwater level, stage-volume inputs and summarises water balance inputs over a common timeseries.

Usage

summarise_inputs(
  lake,
  weather,
  lst,
  isotopes,
  lake_levels,
  gw_levels,
  dictionary,
  threshold = 0.01,
  start_date = NULL,
  end_date = NULL,
  annual = FALSE
)

Arguments

lake	name of lake (e.g., Pleasant, Long, or Plainfield)
weather	a data frame with sub-monthly weather including including date (POSIXct), atmp (air temperature, deg C), P (precipitation, mm), RH (relative humidity, percent), Rs (solar radiation, MJ), and wind (wind speed, m/s)
lst	a data frame with sub-monthly lake surface temperature measurements as formatted in the lst_HOBO dataset, subset for a single lake.
isotopes	a data frame with isotopes measurements as formatted in the isotopes dataset, subset for a single lake.
lake_levels	a data frame with daily water level measurements as formatted in the lake_levels dataset, subset to lake level records for the lake of interest.
gw_levels	a data frame with daily water level measurements as formatted in the lake_levels dataset, subset to groundwater level records at the lake of interest.
dictionary	a data frame with site id numbers and static isotope site classifications as formatted in the dictionary dataset, subset to records for the lake of interest.
threshold	minimum median difference between lake levels and groundwater levels during the month of measurement in order to classify groundwater measurement.
start_date	optional start date to use for analysis (first day of the month) in POSIXct. If not provided, defaults to NULL and timeseries is based on months with isotope samples.
end_date	optional end date to use for analysis (last day of the month) in POSIXct. If not provided, defaults to NULL and timeseries is based on months with isotope samples.
annual	defaults to FALSE to calculate water balance on a monthly basis. If TRUE, calculates the annual balance instead.
