Title:Rincon, Puerto Rico, wave and water level data, 2020 Abstract:
Time series data of wave height and water surface elevation were acquired for 135 days at six locations off of the west coast of Rincon, Puerto Rico, in support of a study on the coastal circulation patterns and the transformation of surface waves over the coral reefs. The relative placement of sensors on the reef were as follows:
PRI20N01 – offshore
PRI20N02 and PRI20N03 – fore reef
PRI20N35, PRI20N04 and PRI20N45 – reef flat

The measurements of waves and water levels from these instrument deployments provide information on the variability of waves on the coral reefs of western Puerto Rico. These data will be used to study the transformation of waves over the reef and how this process contributes to water levels, runup and the potential for flooding of the coast.
Raw data from each instrument were exported to ASCII text files using the manufacturers software, RBR Ruskin v2.8.0, on an Apple Macintosh Personal Computer running OS10.11.6. Exported data were QA/QC’d and exported to netCDF in Matlab R2017a. During post-processing, data collected when instruments were out of the water, and data degraded by biological fouling, were removed from the time series. Bad data points were identified by 1) the deployment and recovery times, and 2) pressure readings equal to or less than 3 cm of water. The raw pressure readings include the pressure from both the overlying water and the atmosphere, and therefore have to be corrected to remove the atmospheric pressure. Data on atmospheric pressure were downloaded from a local weather station maintained by the National Oceanic and Atmospheric Administration (Station MGZP4-9759394 in Mayaguez, Puerto Rico, https://www.ndbc.noaa.gov/station_page.php?station=mgzp4). The data on barometric pressure were interpolated to the burst interval of the pressure measurements, and a single value was removed from each burst.

Files are named with a convention that uses a 13-digit alpha-numeric code. The first three characters for this dataset are all 'PRI' for the experiment name; the fourth and fifth positions represent the calendar year in which the first data point in the file was taken (20, 2020); the sixth, seventh and eighth characters are an alphanumeric code for the site name (N02, N03 etc.); the ninth and tenth characters represent the instrument position on the platform, where 01 is the top-most. Next is a two or three-character code for data type (rbr, RBR Wave). The suffix of ‘-b’ indicates that these are the raw burst data.

How accurate are the heights or depths?
No formal assessment of vertical accuracy was performed. The stated accuracy of the pressure sensor on the wave gauge is +/- 0.01 decibars, which is approximately equivalent to 0.01 meters.
Where are the gaps in the data? What is missing?
