General Description |
|
What data/products do you use? |
Near real-time ocean current data at depth (few) are available via NOAA (NDBC)
|
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, 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 not used for this today.

Information requirements |
|
Update frequency |
Real-time and near real-time. Hourly, or 10 minutes averaged over 1 hour (because of noise).
|
Temporal resolution |
Real-time and near real-time. Hourly or 10 min.
|
Spatial resolution |
Observations 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 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 |
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. |
