R/data.R
MF_obs.RdMF_obs is an sf object with POINT geometry representing water temperature observations and covariates in the Middle Fork Basin, Idaho, USA collected in 2004.
MF_obsAn object of class sf (inherits from data.frame) with 45 rows and 17 columns.
MF_obs are unpublished United States Forest Service data.
The sf data.frame contains 45 point features and 16 columns:
STREAMNAME: Stream name
COMID: Common identifier of an NHD feature or relationship
AREAWTMAP: Area weighted mean annual precipitation (mm) at lowermost location on the line segment where the site resides
SLOPE: Slope of the line segment (cm/cm) where the site resides
ELEV_DEM: Elevation at the site based on a 30m DEM
Source: Source of the data - relates to the ID field of the source table
Summer_mn: Overall summer mean temperature (C) of the deployment
MaxOver20: Binary variable: 1 represents the maximum summer temperature was greater than 20C and 0 indicates that it was less than 20C
C16: Number of times daily stream temperature exceeded 16C
C20: Number of times daily stream temperature exceeded 20C
C24: Number of times daily stream temperature exceeded 24C
FlowCMS: Average stream flow (cubic meters per sec) for August, by year, from 1950-2010 across 9 USGS gauges in the region
AirMEANc: Average mean air temperature (C) from July 15 - August 31, from 1980-2009 across 10 COOP air stations within the domain
AirMWMTc: Average maximum air temperature (C) from July 15 - August 31, from 1980-2009 across 10 COOP air stations within the domain. MWMT = maximum 7-day moving average of the maximum daily temperature (i.e. maximum of all the 7-day maximums)
rcaAreaKm2: Reach contributing area (km2) for the downstream node of the edge feature the site resides on. RCA area is the land area draining directly into each line segment.
h2oAreaKm2: Watershed area (km2) for the downstream node of the edge feature the site resides on
