General Description |
|
What data/products do you use? |
Real-time and near real-time surface-based observations of wind wave heights, swell wave heights, and significant wave heights from ships and buoys are available from many sources including NOAA (NWSTG), NOAA (MADIS), NOAA (NDBC), UCAR, and numerous other data distribution centers.
|
When do you use this kind of dataset? |
These data are used to monitor all day-to-day operations when drilling, surveying etc. To assess current conditions, nowcasting, assess the quality forecast models and plan ahead. Find windows of operability where thresholds apply etc.
|
What are your actual limitations and do you have a work around? |
There are spatial and temporal limitations of real-time and near real-time surface-based and remotely-sensed wave observations. Which means: Data are often not on location. Sensors of different formats, give different parameters, could be shielded, measurements averaged, in "wrong formats'" etc.
|
Needs and expectations on EO data |
EO is used for this today, but resolution, update frequency and quality is not always sufficient. Mostly used as assimilation into models. More severe situations (for instance swells) can be detected using these data real time, however the use for point forecasting is limited.

Information requirements |
|
Update frequency |
Real-time and near real-time. Hourly or 10 min.
|
Temporal resolution |
Real-time and near real-time. Hourly or 10 min.
|
Spatial resolution |
Observation on location or around 4 km
|
Data quality |
The selected sources in this document are selected because they are known to have sufficient quality (after some work around/adaptation). In general separate in-depth verification studies has to be made for each source planned to be used for analysis, and the analysis has to be repeated for each geographical area (since sources might be of sufficient quality in one area but not another).
|
Data Coverage and extent |
Regional and as localized as possible. |
Example format |
Surface-bases observation: text, CSV and/or netCDF
|
Timeliness |
Real-time or near real-time. Forecasts are normally issued 2 to 4 times per day, but industry requires continuous monitoring of. |
Existing standards |
Multiple paragraphs in DNV-RP-C205, OTO 2001/010, ISO-19001-1, NORSOK-N-003e2, and NORSOK-N-006u1 contain extensive references to the standard measures of the means of waves. |
