Extracts carbon monoxide (CO) concentration from Sentinel-5P TROPOMI

Retrieves the CO column number density (mol/m2) for a user-defined region and date range from the Sentinel‑5P TROPOMI OFFLINE L3 CO dataset.

Usage

l4h_co_column(
  from,
  to,
  region,
  stat = "mean",
  scale = 1113,
  sf = TRUE,
  quiet = FALSE,
  force = FALSE,
  ...
)

Arguments

from: Character. Start date in "YYYY-MM-DD" format (e.g., "2020-01-01").
to: Character. End date in "YYYY-MM-DD" format (e.g., "2020-12-31").
region: A spatial object (sf, sfc, or SpatVector) defining the region of interest.
stat: Character. Summary statistic to apply ("mean", "median", "max", etc.).
scale: Numeric. Nominal scale in meters. Default is 1113.
sf: Logical. Return result as sf? Default: TRUE.
quiet: Logical. Suppress progress messages? Default: FALSE.
force: Logical. Force extract without spatial check? Default: FALSE.
...: Arguments passed to rgee::ee_extract.

Value

A sf or tibble containing CO column density (mol/m2) by date and geometry.

Details

The function uses the Earth Engine dataset COPERNICUS/S5P/OFFL/L3_CO and selects only the "CO_column_number_density" band. It supports summarization using a reducer statistic per image.
