General Description |
|
What data/products do you use? |
Real-time and near real-time surface-based observations of 10m wind speeds 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 10m wind observations. The observation heights and averaging periods of wind observations are variables that must be reconciled across all record sets prior to analyses. Which means: Data are often not on location. Sensors are too high, 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 (se hurricanes, squalls etc.) 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 arounds and adaptations). In general separate indepth 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 localised 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 continuous monitoring of conditions is required. |
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 winds. |
