interpolate_to_t#

interpolate_to_t(A, *, stagger, mask_t)[source]#

Interpolate a staggered field (U or V) onto the T grid.

Parameters:

  • A (ndarray) – Staggered array. Last two dims are (y, x). - If stagger=’u’: shape (…, ny_t, nx_t-1) - If stagger=’v’: shape (…, ny_t-1, nx_t)

  • stagger ({'u', 'v'}) – Type of staggering.

  • mask_t (ndarray of 0 and 1) – 0: land point. Will be considered as nan value

Returns:

  • T (ndarray) – Interpolated values on T grid, shape (…, ny_t, nx_t), masked as NaN where mask_t is True.

  • single_src (ndarray (uint8)) – 1 where T was computed from exactly one valid neighbor, 0 otherwise. (Interior points with two valid neighbors → 0; points with both neighbors NaN → 0.)
