Saddle - Meteorological Data


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 : 3528 m (11,572 ft)

The following meteorological data are from the Saddle 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.

Saddle Summary

The Niwot Ridge saddle is located 5.6 km from the Continental Divide. The area is located along the ridge-top, but in a shallow saddle between the east and west knolls. There is a 10,000 ft2 tundra laboratory on the south side of the saddle, which serves as a staging area for research in all weather conditions. In addition, there is an 80 ft2 subnivean laboratory equipped with snow melt lysimeters that drain into dedicated tipping buckets. These laboratories have year-round motorized access 120-volt line power. There is an Aerometrics wet—chemistry precipitation collector as part of the National Atmospheric Deposition Program (NADP), which has operated continuously since 1984 and is the highest site in the entire NADP network. The timing, duration, and amount of snow cover has been manipulated since 1994 with a 2.6 x 60 m snowfence, providing a proxy for climate change. There are several meteorological stations at the Saddle site. Climate data exists for 1981 to the present and includes temperature, relative humidity, solar radiation, barometric pressure, wind speed and direction, precipitation, soil moisture and temperature. NOAA measures surface ozone as well.
