uataq.errors.DroppedPollutantWarning

exception uataq.errors.DroppedPollutantWarning

Warned when a read of several pollutants leaves one out for want of data.

get_obs and get_recent_obs issue it when none of the instruments that measure a pollutant you asked for gave data (no files for the range, or not installed then), so the table has no column for it. The read did not fail: the other pollutants are returned. Silence it with warnings.filterwarnings("ignore", category=uataq.errors.DroppedPollutantWarning).
