Why earthkit-transforms?

earthkit-transforms provides a library of quality assured methods for transforming and analyzing climate and meteorology data. There is a focus on a clear and simplified API to complex transformations, whilst ensuring that accuracy and performance are not compromised. The methods are designed to be intuitive and self-explanatory to encourage their use and to make them accessible to a wide range of users, from beginners to experts.

Key features include:

⚙️ Concise, high-level API - Compute complex transformations with simple, intuitive methods.

🧠 Intelligent data handling - Data format and structure is handled automatically, so you can focus on the analysis.

⚡ Performance and scalability - Compatible with both CPU and GPU, and with data objects that are lazily loaded or in-memory, ensuring efficient processing of large datasets.

🎨 Plug-and-play with earthkit-plots - The results of transformations are designed to be easily visualised with the companion library, earthkit-plots, with methods that return plot-ready objects.

earthkit-transforms is used in a number of ECMWF projects, including the on-the-fly production of Daily statistics for the ERA5 reanalysis, in the backend processing of Climate Change Service Global temperature trend monitor, and is used to produce the anomaly data visualised in the famous climate stripes, as demonstrated below.
