This table identifies the types of sensors used on TAO moorings and lists their accuracies. Most instrumental accuracies listed are based on pre-deployment and post-recovery calibrations and are the root mean square drift of a group of sensors. Mechanical current meters and current profilers accuracies are based on intercomparisons between co-located instruments. References where available are indicated by [#] in the comments column and listed at the end of the tables. Accuracies of sensors which are new to TAO moorings (longwave radiation, barometric pressure) or which have not yet been evaluated by TAO (water pressure) are those specified by the manufacturer and are indicated by [M].
In cases where sensors
are paired with PMEL supplied electronics (e.g., analog to digital boards)
calibrations include both the sensor and PMEL electronics. Accuracies
listed here (with the exception of currents) do not include environmental
factors such as wind (on rainfall) or buoy motion(on radiation). Measurement
ranges listed are generally those over which the sensors are calibrated.
The ranges over which a sensor will operate (determined by the sensor
and/or PMEL electronics) are listed in parenthesis if they significantly
exceed the calibration range.
A comparison of ATLAS,
TRITON, and IMET mooring meteorological sensors from a land-based intercomparison
study at the Woods Hole Oceanographic Institution in May-June 2000 shows
that in general the three systems measure to equivalent standards of accuracy.
