Get observations for a given variable from an Aeme object

Usage

get_obs(aeme, var_sim, depth_range = NULL, time_filter = FALSE)

Arguments

aeme

Aeme object.

var_sim

character; variable in the AEME format (e.g. "HYD_temp"). Can be a vector. If missing, all variables are returned.

depth_range

numeric vector of length 2; depth range (in meters) to filter observations. If NULL, all depths are returned.

time_filter

logical; if TRUE, filter observations to the time range of the Aeme object. If FALSE, all observations are returned regardless of time.

Value

A data frame with the following columns:

  • Date: Observation date – a UTC POSIXct; daily rows are anchored at 12:00:00

  • var_aeme: Name of the variable in the AEME format

  • depth: Nominal sampling depth (m, positive-down from the surface)

  • value: Value of the variable

  • depth_to: (optional) Bottom of an integrated sample, if recorded

  • sd: (optional) Measurement standard deviation, in the variable's units
