This data release contains all of the available raw rainfall data from the Grizzly Creek Fire perimeter from September 2020 through September 2022. The csv files here are organized by the station name and followed by the year of the data. The locations of the stations are available in the file named (4_Gauge_Location.csv) in the parent data release. The rain gauge data were obtained using two different methods. The gauges named: ‘USGS_’ are non-telemetered gauges and each timestamp represents a bucket tip. The columns in each csv for these gauges includes an Index, Date Time, Name, Serial Number, and Tipping Bucket depth (in units of millmeters). Gauges GCCC2, GCDC2, GCEC2, GCFC2, GCIC2, GCNC2, GCTC2 were operated by the U.S.Geological Survey Colorado Water Science Center (USGS COWSC), and provisional data from these gages were obtained remotely via telemetry. Gauge TT394 was operated by the Bureau of Land Management (BLM), and provisional data from this gage was obtained remotely via telemetry. The USGS COWSC and BLM data have three columns: Date_Time, precip_intervals_set_1d (the depth in millimeters at a timestamp), and precip_accumulated_set_1d (the total accumulated rainfall depth in millimeters). Note that in some cases the data are discontinuous. One rain gauge, Bair Ranch, was operated by the Colorado Department of Transportation in 2021. These data are broken up into different files due to long data discontinuities. The naming format is: Bair_Ranch_start_YYYYMMDD_endYYYYMMDD, indicating the starting and ending year (YYYY), month (MM), and day (DD). These data have two columns Date/Time and 6hr Accum (inches of precipitation in 6 hours).
