Climate Analysis

Use xarray for labelled climate arrays and verde only when scattered spatial observations need interpolation. Existing regular grids do not require a new interpolation stage. Run the relevant stages in one agent; companion skills are helpful references rather than mandatory registrations.

Define the data contract

Identify the variable, physical units, spatial support, timestamp meaning, calendar, time bounds, missing-value encoding and source/version before combining files. Check coordinate uniqueness and order, longitude convention, latitude direction, projection, vertical level and ensemble/member dimensions. Preserve non-Gregorian calendars; do not silently coerce them into ordinary timestamps.
