nearly 7000 weather stations worldwide
stations measure solar and weather data (i.e. temp,
humidity, wind speed, evapotranspiration, soil temp). some sensors aren't
available on all stations.
we use statistical quality control procedures to mark
faulty data. errors may exist as in any large dataset. we avoid
private and coop stations for accuracy.
data is gathered weekly from thousands of us stations and rationalized into a single
database. we collect international and hourly data separately, mostly upon
compare our data to others
