WatObs: Access Water Observation Data

This Python package gives you convenient access to water observation data with a bring-your-own-api-key concept.

Data overview

Example notebooks

Satellite altimetry data

Altimetry data (water level, significant wave height and wind speed) obtained from satellites are very useful for validation of models as the data are available globally since 1985 and up to 12 hour before now.

DHI has an altimetry portal with an api where you can download the data.

Example

Obtain all altimetry data within 100km from (lon, lat)=(2.9, 55.9) from October 2019.

>>> from watobs import DHIAltimetryRepository
>>> repo = DHIAltimetryRepository(api_key)
>>> data = repo.get_altimetry_data(area="lon=2.9&lat=55.9&radius=100", 
                                   start_time="2019-10-1", 
                                   end_time="2019-11-1")
>>> data.df["longitude","latitude","significant_wave_height"].head()

                         longitude   latitude  significant_wave_height
datetime
