Each observation captures one station's report for one day, including maximum and minimum air temperature in degrees Fahrenheit, precipitation in inches, and where reported, snowfall and snow depth in inches. Source data uses two special markers: 'M' for missing values (handled by simply omitting the corresponding triple) and 'T' for trace values below the precision threshold (handled by storing 0.0 and adding a boolean flag like precipitation_is_trace=true). The Weather_Station class itself lives in the GRIP nutrient-management/environment module so that geography is shared across the GRIP ontology suite." ;
