Apply Quality Control to raw AIRSIS E-Sampler dataframe

Source: R/airsis_ESAMQualityControl.R

Perform various QC measures on AIRSIS E-Sampler data.

The following columns of data are tested against valid ranges:

  • Flow

  • AT

  • RHi

  • ConcHr

A POSIXct datetime column (UTC) is also added based on TimeStamp.

airsis_ESAMQualityControl(
  tbl,
  valid_Longitude = c(-180, 180),
  valid_Latitude = c(-90, 90),
  remove_Lon_zero = TRUE,
  remove_Lat_zero = TRUE,
  valid_Flow = c(1.999, 2.001),
  valid_AT = c(-Inf, 150),
  valid_RHi = c(-Inf, 55),
  valid_Conc = c(-Inf, 5000),
  flagAndKeep = FALSE
)
