The data are summaries from the vaisala (air pressure, relative humidity and air temperature) and the R3-Sonic anemometer (wind speed, direction and flux data). These instruments are not part of our core data. They are only supported when there are research projects which support their deployment and maintenance.
The sensors are located at the air-sea interaction tower on a mast. They are approximately 18.4 meters above sea-level.
More detailed statistics are available in the vais_s and 3D1_s data.
Most of the data parameters include values for the mean and median value as well as the standard deviation of the variable. The table below shows the field name suffix used to differentiate among the different values:
Here is the list of field names:
|Year||The year the data were collected||n/a|
|Yday||Decimal year day||UTC, January 1 at 00:00 is 1.0|
|MO||The month the data were collected||UTC|
|DA||The day the data were collected||UTC|
|HH||The hour the data were collected||UTC|
|MM||The minute the data were collected||UTC|
|SS||The second the data were collected||UTC|
|wdir_3D1||Wind Direction (Met convention 180=winds from South; 225 from SW)|
|tair_vais||air temperature||Degrees C|
|w_3D1_std||vertical wind flux|
|uv_3D1_var||horizontal wind flux|
|uw_3D1_var||crosshore vertical wind flux|
|vw_3D1_var||along-shore vertical wind flux|
|wTv_3D1vais_var||latent heat flux|
|lrec_3D1||number of records used in computing statistics (3D1)|
|lrec_vais||number of records used in computing statistics (vais)|
|lrec_campmt||number of records used in computing statistics (campmt)|
