Historical Observations Data Platform QAQC Scripts, v1.1.0

The Historical Observations Data Platform is a cloud-based, historical weather observations database to support access to high-quality, open climate and weather data. The Platform has sourced station data from from 27 publicly available historical data observation networks across the Western Electricity Coordinating Council (WECC) domain from 1980-2022 (time period varies between networks and stations). A total of 14,927 stations have completed the full quality control and standardized pipeline and are publically available as cloud-optimized zarrs, with helper functions to convert to other formats as desired. The Platform responds to community partner needs, focused on California's energy sector, in understanding weather and climate information including the severity, duration, frequency, and rate of change over time of extreme weather events, as well as supporting projections downscaling efforts. We implement stringent QAQC procedures, in line with international standards, and have built customized modifications relevant to western North America and the energy sector, including temperature and precipitation extrmemes, winds, and solar radiation.
