General Description |
|
What data/products do you use? |
Near real-time ocean surface current data are available via NOAA (NDBC)
Surface currents derived from satellite
|
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 the current conditions, nowcasting, assess the quality forecast models and plan ahead. Find windows of operability etc.
|
What are your actual limitations and do you have a work around? |
Data availability is the major issue. Few measurements of sufficient quality exist.
|
Needs and expectations on EO data |
EO is used for this today, but resolution, update frequency and quality is not sufficient. Increasingly used as assimilation into models. More severe situations (for instance eddies/loop current) 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 minutes averaged over 1 hour (because of noise).
|
Temporal resolution |
Surface-based observation: sub-hourly to less frequently
|
Spatial resolution |
Observation on location or around 4 km (maybe less in coastal areas).
|
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 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 localized as possible. |
Example format |
netCDF and/or CSV |
Timeliness |
Real-time or near real-time. Forecasts are normally issued 2 to 4 times per day, but industry requires continuous monitoring of conditions. |
