EPT-1.5 Hindcasts

For detailed information about the EPT-1.5 model, including technical specifications and available parameters, see the EPT-1.5 Model Overview.

Important Parameter Naming Disclaimer:

• Parameter names have changed from ECMWF shortnames to human-readable longnames based on customer requests (e.g., "2t" is now "air_temperature_2m" in newer products)

• For EPT-1.5 hindcasts, the original shortnames (2t, 10si, etc.) will remain unchanged and will not be updated to the new naming convention
