Apply Quality Control Checks to Meteorological Data

apply_qc.Rd

Applies range-based quality control to a `metamet` object by setting out-of-range values to `NA` and recording QC codes in the `qc` column. Accepts both wide and long format; always returns long format.

Usage

apply_qc(mm0)

Arguments

mm0

A `metamet` object (wide or long format).

Value

A long-format `metamet` object with updated `value`, `qc`, and `validator` columns.

Details

The function performs the following steps:

  1. Reshapes to long format if necessary.

  2. Sets values outside the min/max range specified in `dt_meta` to `NA`.

  3. Sets `qc = 1` for missing or invalid values, `qc = 0` for valid values.

  4. Sets `validator = "auto"` for flagged rows.

Examples

# mm_qc <- apply_qc(mm)
