automatic_weather_stations (deprecated)#

easysnowdata.automatic_weather_stations#

SNOTEL and CCSS station data — a shim over easysnowdata.stations.

Deprecated since version 0.1.0: Use easysnowdata.stations.inventory() and easysnowdata.stations.load() (or easysnowdata.stations.archive.load()). StationCollection is kept for one minor release and removed in 0.3.0.

The data no longer comes from the frozen egagli/snotel_ccss_stations archive: that route is gone, with no transition period (§12 Q9). Every call below now reaches the live AWDB and CDEC clients, or the daily archive global_snow_networks publishes, through the Phase 3 adapter. What that changes, and what it does not:

  • Station codes are unchanged. 679_WA_SNTL still means Paradise; the adapter maps it to the AWDB triplet 679:WA:SNTL on the way out.

  • Variable names are unchanged. WTEQ, SNWD, PRCPSA, TAVG, TMIN and TMAX still name the columns, mapped to the standardized types the networks speak (swe, snwd, precip, temp, temp_min, temp_max).

  • Units are unchanged. The old CSVs held metres and millimetres of water; the networks emit centimetres and millimetres. The shim converts back, so the numbers a notebook plots are the same ones it plotted before.

  • The station list is larger and current. It comes from the live inventory rather than a 2024 snapshot, so stations added since then appear and endDate reflects today.

  • SNOTEL air temperature is a newer vintage, and that is a fix rather than a regression. TAVG, TMIN and TMAX map to the same AWDB elements the frozen archive used, but their values differ for roughly 2004-2024 at the stations NRCS bias-corrected: the frozen CSVs hold the uncorrected series, about 1.1 °C warm, because that archive’s updater only ever rewrote the last ten days and never re-fetched history. Verified against both AWDB REST and the CUAHSI WaterOneFlow service the frozen archive itself used, which agree with each other to 0.02 °C. At Paradise the offset spans 2004-2024 and is zero either side; 303:CO and 457:CO show the same shape; 642:WA shows none. Reading live means you get the corrected values, so a Paradise winter mean moves from -1.55 °C to -2.95 °C.
