Description
A dataset containing hourly observations, and hourly predictions of tidal
elevations at the NOAA tide gauge in Providence, Rhode Island.
Station ID: 8454000.
Usage
1
Format
A data frame with 630,255 rows and 11 variables:
- DateTime
Year of mean sea level observation
- theDate
Month of mean sea level Observation
- Hour
Hour of observation, as an integer in the range 1:24
- Day
Day of the month of the observation, as an integer
- Month
Month of observation, as an integer in the range 1:12
- Year
Year of observation, as an integer
- MLLW
Observed tidal elevation, in meters above mean lower low water
- MLLW_ft
Observed tidal elevation, in feet above mean lower low water
- Prediction
Predicted tidal elevation, in meters above mean lower low
water
- Prediction_ft
Predicted tidal elevation, in feet above mean lower
low water
- deviation
Difference between observed and predicted tidal heights.
positive values imply observed sea level was above predicted levels.
Details
Data is available from Providence for the period from 1938 through 2021, with
some gaps in the data. Data included here omits tide predictions for dates
and times without corresponding observational data. Released version of the
package may include a subset of the data to make the package leaner.
Values are expressed relative to the most recent mean lower low water tidal
datum. Water depths on navigational charts are ordinarily expressed relative
to mean lower low water. At the time of data download, the tidal epoch used
for calculating the tidal datums was from 1983 through 2001.
Data as released by NOAA was downloaded directly from a NOAA API using
python scripts. Details on the API are available from the NOAA web page,
https://tidesandcurrents.noaa.gov/api/. Similar data can be downloaded
manually from the official station webpage, listed as the data source, below.
We combined records of observed water levels and predicted water levels into
a single large data frame.
