# NOAA Buoycam Dataset |
|
This dataset provides NOAA buoycam images paired with meteorological observation data from the time the image was captured. |
|
|
|
## Dataset Details |
|
Created using SeeSea (https://github.com/BrianOfrim/SeeSea) |
|
|
|
## Json Observation Data: |
|
|
|
|
|
| Key | Type | Unit | description | |
|
|--------------------------|--------|---------------------|------------------------------------------------------------| |
|
| station_id | string | N/A | Id of the buoy |
|
| timestamp | string | YYYY_MM_dd_HHmm | Date/time of image & observation |
|
| description | string | N/A | Data | Description of buoy location |
|
| lat_deg | float | degrees [-90, 90] | Latitude |
|
| lon_deg | float | degrees [-180, 180] | Longitude |
|
| wind_speed_mps | float | meters / second | Average wind speed |
|
| wind_direction_deg | float | degreesT | Wind direction |
|
| gust_speed_mps | float | meters / second | Peak wind speed |
|
| wave_height_m: | float | meters | Wave height |
|
| dominant_wave_period_s | float | seconds | Dominant wave period |
|
| average_wave_period_s | float | seconds | Average wave period |
|
| mean_wave_direction_deg | float | degreesT | The direction from which the waves at the dominant period are coming |
|
| atmospheric_pressure_hpa | float | hectopascal | Sea level pressure |
|
| air_temperature_c | float | celcuis | Air temperature |
|
| water_temperature_c | float | celcius | Sea surface temperature |
|
| dewpoint_temperature_c | float | celcius | Dewpoint temperature |
|
| visibility_nmi | float | nautical miles | Station visibility |
|
| pressure_tendency_hpa | float | hectopascal | Pressure change in the previous 3 hours |
|
| tide_m | float | meters | Water level |

| image_direction_deg | float | degreesT | The direction of the image\* |
|
|
|
degreesT = degrees clockwise from true north |

|
|
\* image_direction_deg is read from the full buoycam image using OCR. The data is almost certainly invalid as all first images are reported to start at 90 which is very unlikely. |
