What does this program measure?
The ESRL GMD Meteorology program measures ambient and dewpoint temperatures, relative humidity, precipitation (in inches), and wind speed and direction.
How does this program work?
The dewpoint hygrothermometer measures ambient and dewpoint temperatures, from which relative humidity is calculated. Precipitation is continuously measured (in inches) with a tipping bucket.
In order to monitor the trends in meteorological parameters, and to assist in the interpretation of other parameters such as aerosols.
Are there any trends in the data?
Day rose and night rose (below) show the wind direction at the observatory. Note that the night rose shows only the southerly component which is the desired downslope conditions.
How does this program fit into the big picture?
What is it's role in global climate change?
It allows us to see how changes in other atmospheric variables affect the meteorology of the station.
