A preliminary analysis examined group differences in weather conditions, missing observation data, and school enrolment size.
We merged mortality data, ED visit data, weather observations and air pollution data by date.
(Within each state, hundreds of weather observation stations record hourly data on temperature, rainfall, and other conditions).
We merged mortality data, weather observations, forecasts, and air pollution data by date.
Not until the middle of the 19th century would the debate on North American climate change finally be put to rest by early climatologists who had cranked out numbers by hand from sparse and slowly accumulating weather observations and phenological data.
Another limitation was that this study used weather data from only one weather observation station for each community; however, a community in this study covered a relatively small geographic area, and the weather data from one station could generally represent the local weather pattern.
Observation data of the German weather service [[36]] were checked, homogenised and interpolated to the 10-km grid [[49]].
Even though the accuracy is a bit lower than data from big national weather observation stations, we have quantity and our goal now is to change the quality," he says.
The wind observation data were obtained from ground weather stations.
Additionally there are automated weather observation stations (AWOSs) and smaller weather observation sites that contribute data to the NCDC.
