Overview

Daily snow water equivalent, snow depth, precipitation and temperature at HUC 17 SNOTEL and SNOLITE stations, with the 30-year median and average for % of normal.

Query contract

Preserve one canonical row per (station_triplet, element_code, ordinal, date) before aggregating.

Analysis rules

  • Filter one element_code; % of normal is value / median for WTEQ and PREC.

Interpretation

  • HUC 17 includes the coast and Puget Sound; filter HUC 1701-1709 for the Columbia alone.
