WARNING: These data are raw and have not been quality checked.
Q - questionable data based on preliminary automated quality control.
I - nonsensical data based on the physical range of the variable.
These flags will show up on the graph if any data points trip the automated quality control criteria.
Station Elevation : 3022 m (9,912 ft)
The following meteorological data are from the C1 station on Niwot Ridge. The peak wind gust information is recorded instantaneously, with a sampling interval of 5 seconds. The other measurements are one hour averages comprised of 720 samples collected at 5 second intervals. All the parameters are updated at the top of every hour. This page is also available displayed in U.S. customary units.
The C-1 climate station is located on a ridge-top in a subalpine forest, 9.7 km east of the Continental Divide. Climate data exists from the C-1 station for 1953 to present, and includes temperature, relative humidity, solar radiation, barometric pressure, wind speed and direction, precipitation, soil moisture and temperature, snow depth. Hydrologic data exists from twelve ground water wells and twelve soil lysimeters installed at the site in 2010. Water samples for lab analysis are collected from ground water wells, soil lysimeters, and surface water from nearby Como Creek. Samples are analyzed at INSTAAR’s Kiowa Lab.
The Niwot Ridge LTER operates a National Atmospheric Deposition Program National Trends Network (NADP NTN) site CO90 at this station, which has been in operation since 2006, and is one of three NADP NTN sites at Niwot Ridge.
At this site are also atmospheric and ecological research operations run in cooperation with the LTER and University of Colorado. There is an NRCS Snotel site located at C1. NOAA operates several monitoring projects at the C1 location including: the Global Monitoring Division (ESRL GMD), Carbon Cycle Greenhouse Gases (CCGG), Halocarbon and other Atmospheric Trace Species (HATS), and Ozone and Water Vapor groups measurements of anthropogenic greenhouse gases, stratospheric ozone depletors, and surface ozone measurements, a National Weather Service Cooperative Observers Network (NWS COOP) precipitation gage, and a US Climate Research Network (USCRN) weather station. South of the C1 station is an AmeriFlux tower (forest ecology and atmospheric flux).
