grid: time=528 lat=165 lon=244
input: scale=6; calibration=1991-2020; distribution=gamma; zeros replaced with 0.01 mm; land mask from the first time step (16134 of 40260 cells); spatial axes rolled by lat=0 lon=-1 so the sampled preflight cell holds data
environment: python 3.13.13; macOS-26.6.2-arm64-arm-64bit-Mach-O; numpy 2.4.2; scipy 1.17.0; xarray 2026.1.0; dask 2026.1.2; cpu Apple M5; 10 CPUs
process: read 1.012 s; 3 timed runs per configuration after a warm-up

spi eager serial in-memory (quiet log): samples=[34.347, 34.458, 34.560] min=34.347 s; read=1.012 s; write=0.032 s; total=35.391 s

Dask worker counts: 1,2,4,8; scheduler=processes; chunksize=1; time=-1 (ADR-0003); compute-only seconds, total adds read + write
