GHRSST specified/formatted products: Which SST products in GHRSST specification are the most suitable for me?
This training was held as in-person training on 20 October 2023, at the GHRSST24 symposium, in Ahmedabad. The training material is now available for those who would like to learn at their own pace. All the modules have been recorded and the materials are accessiblein the Moodle.

About
GHRSST coordinates an extensive catalogue of Sea Surface Temperature (SST) produced by many data producers, each with its advantages and caveats. For a potential user, with a given application in mind, this landscape can be confusing and intimidating, often resulting in reaching for the most convenient product, irrespective of its suitability.
This course aims to connect users to the catalogue more appropriately, outlining the ramifications for selecting level-4 gridded products of a given type (e.g. IR, microwave, blended) and therefore allowing them to make better-informed choices for their applications. It will consider practical examples of a broad range of applications from the meso- to global scale, from event-based to climate variability. The course will provide a basic introduction to L2, L3 and L4 fields as many potential users have very little knowledge about these, and need guidance to decide what they need for their studies and many are unaware of the consequences of their choices.

Specific objectives of the training
Increase knowledge on GHRSST coordinated products for SST users.
Target audience and level of experience
Newcomers (e.g., undergraduates, stakeholders such as small-scale fishers, environmental managers, and early career scientists) who are interested in learning how to use satellite-derived SST data. Participants should have minimum familiarity with Python.
Practical Information
Please read the following information before attending the training. You should ensure that you bring the right equipment and prepare a few things before get the most out of the training. The training will be hands-on and in-person.
Equipment
There will be hands-on exercises throughout the training, therefore, you must work on your computer during the training.
What to do before the training
Please ensure that you have the following installed on your computer:
- Jupyter Framework: Project Jupyter | Home
Please register and set-up an account for the following:
- Create an WEkEO account: Copernicus and Sentinel data at your fingertips | WEkEO
- Register to Copernicus Marine Service (Register to Copernicus Marine Service | CMEMS). You should have your username and password.
