OtherStationRecords: Available meteorological and snow course station data (water years 2010-2014) from the California Department of Water Resources, NOAA, Merced Irrigation District, NRCS, Hetch Hetchy Water and Power, Pacific Gas & Electric, and Bureau of Land Management Fire Remote Access Weather Stations SpatialData: Vector and raster data that cover the spatial domain for these climate data *Roche, J. W., Bales, R. C., Rice, R., & Marks, D. G. (2018). Management Implications of Snowpack Sensitivity to Temperature and Atmospheric Moisture Changes in Yosemite National Park, CA. JAWRA Journal of the American Water Resources Association, 54(3), 724-741. DOI:10.1111/1752-1688.12647 Within each collection of records, there are 3 directories with data: Level 0: raw data from datalogger Level 1: QA/QC data Level 2: gap-filled data and derived hourly and daily data Level 0 data files are .csv or .csa (also comma-separated text files) files identified by site, water year, and data-type. Level 1 and Level 2 data are comma-separated value text files. All .csa and .csv files should be readable in any basic text editor. Plots of Level 2 data are saved as PDF in the AllDataPlots folder. Specific to UCMStationRecords: Snow depth (m), air temperature (Deg C), soil volumetric water content (VWC) and soil temperature (Deg C) data are measured at multiple sites within an area of 1-3 hectares. The full date range is water years 2009-2015. Missing data may be the result of instrument or datalogger failure as well as the addition of sensors over the years. Snow depth is measured in the open, at the drip edge and under canopies and well as an additional 2-4 node locations per site. Soil volumetric water content (VWC) and temperature are measured at 10, 30, 60 and 90 cm depths coincident with the open, edge, and under snow depth nodes. Column Headers for Level 2 snow data are: Date_time_PST: Pacific Standard Time and Date as mm/dd/yyyy hh:mm; Date_time_UTC: Coordinated Universal Time and Date as mm/dd/yyyy hh:mm; SnowD_m: snow depth in meters; SnowT_C: air temperature in degrees Celsius; Snow data are available in original 15-minute increments as well as hourly and daily averages. Column Headers for Level 2 soil data are: Date_time_PST: Pacific Standard Time and Date as mm/dd/yyyy hh:mm; Date_time_UTC: Coordinated Universal Time and Date as mm/dd/yyyy hh:mm; 10cm_VWC_m^3/m^3: Volumetric water content at 10cm below ground surface; 10cm_SoilTemp_C: Soil temperature (degrees C) at 10cm below ground surface; 30cm_VWC_m^3/m^3: Volumetric water content at 30cm below ground surface; 30cm_SoilTemp_C: Soil temperature (degrees C) at 30cm below ground surface; 60cm_VWC_m^3/m^3: Volumetric water content at 60cm below ground surface; 60cm_SoilTemp_C: Soil temperature (degrees C) at 30cm below ground surface; 90cm_VWC_m^3/m^3: Volumetric water content at 90cm below ground surface; 90cm_SoilTemp_C: Soil temperature (degrees C) at 30cm below ground surface; Soil data are in 15-minute increments. Missing values: NaN, -9999, and Specific for Scripps Station Records: Only air temperature (airtemp C) and relative humidity (RH %) are processed to level 1 and level 2. Other logged parameters included with level 0 data are 1-minute data for barometric pressure, a second temperature sensor, temperature of the data-logger housing, temperature sensor with the RH sensor, precipitation via unheated tipping bucket gauge, and solar radiation, and 1-hour data for fuel moisture temperature and %, and soil moisture %volumetric weight content and temperature at 10cm, 30cm, 60cm, and 90cm depths. Note that all times in raw data are UTC (PST+8). Questions regarding raw data should be directed to Dr. Dan Cayan and Douglas Alden at Scripps Institution of Oceanography. Column Headers for Level 2 data are: date_time: Pacific Standard Time and Date as mm/dd/yyyy hh:mm; airtemp C: Air temperature in degrees Celsius; RH %: Relative humidity in %; code: gap-filling code (1=linear interpolation and 2=regression with a nearby station) Missing values: Hourly data are extracted from 1-minute data for the zero minute and are not averages Specific for the Other Station Records: Stations with available temperature, relative humidity, solar radiation, wind speed and direction, and precipitation records were processed to level 1 and level 2 for water years 2010-2014. Not all level 0 records were processed if they were outside the the desired date range and for reasons of poor quality. Column Headers for Level 2 data are: date_time: Pacific Standard Time and Date as mm/dd/yyyy hh:mm; airtemp C: Air temperature in degrees Celsius; RH %: Relative humidity in %; solar_rad w/m2: Solar radiation in watts per meter squared; wind_speed m/s: Wind speed in meters per second; wind_direction deg: Azimuth of wind direction; precip_accum mm: Accumulated precipitation since beginning of water year in mm; precip_inc mm or ppt mm; Incremental hourly precipitation in mm; SWC mm; Incremental or accumulated (see file name) hourly or daily increase in snow water content (equivalent); code: gap-filling code (1=linear interpolation, 2=regression with a nearby station, 5=filled with value from adjacent station) Missing values: -99, NaN, Specific for the Spatial Data: Data in this folder are: all_sites: ESRI point shapefile of all station locations and elevations in the dataset; locations were obtained from on-line documentation where available, GPS, and Google Earth; elevations were derived from on-line resources and USGS National Elevation Dataset (10-meter); calveg_cc.asc: ESRI ASCII 100-m raster of canopy cover derived from the Calveg database (https://www.fs.usda.gov/detail/r5/landmanagement/resourcemanagement/?cid=stelprdb5347192 as accessed on August 18, 2018); raster cell is a spatial average of intesecting polygons; calveg_codes.asc: ESRI ASCII 100-m raster of vegetation-type reference numbers from the Calveg database (https://www.fs.usda.gov/detail/r5/landmanagement/resourcemanagement/?cid=stelprdb5347192 as accessed on August 18, 2018); raster cell value is vegetation type covering the most area of intersecting polygons; calveg_height.asc: ESRI ASCII 100-m raster of canopy height derived basal area estimates (see Roche et al., 2018 for details) from the Calveg database (https://www.fs.usda.gov/detail/r5/landmanagement/resourcemanagement/?cid=stelprdb5347192 as accessed on August 18, 2018); calveg_mu.asc: ESRI ASCII 100-m raster of canopy light transmissivity extinction coefficient (see Roche et al., 2018 for details) based on vegetation type from the Calveg database (https://www.fs.usda.gov/detail/r5/landmanagement/resourcemanagement/?cid=stelprdb5347192 as accessed on August 18, 2018); calveg_tau.asc:ESRI ASCII 100-m raster of canopy light transmissivity (see Roche et al., 2018 for details) from the Calveg database (https://www.fs.usda.gov/detail/r5/landmanagement/resourcemanagement/?cid=stelprdb5347192 as accessed on August 18, 2018); merced_tuolumne_100mdem_utm.asc: ESRI ASCII 100-m digital elevation model derived from USGS National Elevation Dataset 10-meter resolution raster with a NAVD88 vertical datum; merced_tuolumne_100m_utm_mask.asc: ESRI ASCII 100-m raster mask of the Merced and Tuolumne watersheds (0 = outside watershed; 1 = inside watershed); Merced_utm: ESRI polygon shapefile of the Merced River watershed above Exchequer Dam; Tuolumne_utm: ESRI polygon shapefile of the Tuolumne River watershed above New Don Pedro Dam; All files are in Universal Transverse Mercator Zone 11 Projection using the 1983 North American Datum.
