How to request and use our products

This page gathers all the documentation describing how to request and use the data of the CyclObs website.

Product request

Data can be downloaded through two means :

• Specific cyclone/file download : using the "Access data for this cyclone" link, reachable by browsing to a cyclone on the CyclObs website. Specific cyclone acquisition files are then downloadable with the "Download" link.
• Massive and customizable download : In a first step, the CyclObs application programming interface (API) enables to retrieve meta-data characterizing satellite acquisitions and storms from our database. In a second step, the data are downloaded with respect to these meta-data.
  See CyclObs API documentation to see how to use it.

Complete usage examples

Python jupyter notebooks are used for the following examples. The notebooks are available for download.
To install jupyter : Jupyter documentation
