The NOAA Tidal Analysis Datums Calculator (TAD) reads a time series of water level data and calculates several tidal datums. This lesson provides step-by-step instruction on using TAD. It describes data and metadata requirements, the processes used by TAD to compute datums, and the information contained in the output files. After completing the lesson, the learner will be able to determine tidal datums using TAD.
After completing the lesson, the learner will be able to do the following:
Describe what the NOAA tidal analysis datums calculator (TAD) does and how it does it.
Describe the data format read by TAD.
Describe the data requirements (minimum length of record, data gaps).
Describe the processes TAD uses to compute datums (FRED, MMSC, TBYT).
Describe how TAD determines which process to utilize.
Describe the output files computed by TAD.
List the output files.
Describe the contents of the SDC.out file.
Given a properly formatted dataset, determine tidal datums using TAD.
