Climate Database

The climatic database divides the data into four type: daily climate, 6-hourly climate, hourly precipitation, and 1- & 3-hourly climate.

Daily Sample Data

Parameters:

Maximum air temperature (degrees F)
Minimum air temperature (degrees F)
Mean air temperature (degrees F)
Precipitation (inches)
Snowfall (inches)
Snowdepth (inches)
Wind (miles/day)
Evaporation (inches)
Maximum evaporation pan temperature (degrees F)
Minimum evaporation pan temperature (degrees F)
Mean evaporation pan temperature (degrees F)

6-Hourly Data

Parameters:

Air temperature:

6-hour (degrees F)

Daily maximum (degrees F)

Daily minimum (degrees F)

Monthly maximum (degrees F)

Monthly minimum (degrees F)
Relative humidity:

6-Hour (percent)

At maximum temperature for day (percent)

At minimum temperature for day (percent)

Mean per month (percent)
Atmospheric pressure (adjusted to sea level)

Maximum pressure for day (inches Hg)

Minimum pressure for day (inches Hg)

Maximum pressure for month (inches Hg)

Minimum pressure for month (inches Hg)

Hourly Precipitation Data

Parameters:

Hourly precipitation (inches)
Monthly total precipitation (inches)

1- and 3-Hourly Data

Parameters:

Dry bulb air temperature (degrees F)
Wet bulb air temperature (degrees F)
Dew-point temperature (degrees F)
Relative humidity (degrees F)
Wind speed (miles per hour)
Wind direction (16 compass points)

Note: An hourly average computed per month is also stored for all 1- & 3-hourly items except wind direction

Header information for a given station includes latitude-longitude, township-range, county-state, elevation, drainage basin code and source organization.
