Wind Profiler and RASS Measurements Compared with Measurements from a 450-m-Tall Tower
Publisher: American Meteorological Society
Abstract: A 915-MHz boundary layer wind profiler with radio acoustic sounding system (RASS) was sited 8 km from a very tall (450 m) television transmitting tower in north-central Wisconsin during the spring, summer, and autumn of ...
A Design for Unattended Monitoring of Carbon Dioxide on a Very Tall Tower
Publisher: American Meteorological Society
Abstract: Unattended measurements of carbon dioxide (CO2) mixing ratio at three altitudes up to 496 m above the surface on a television transmitter tower in the southeastern United States have been made for a period of 4 yr. This ...
Long-Term Observations of the Dynamics of the Continental Planetary Boundary Layer
Publisher: American Meteorological Society
Abstract: Time series of mixed layer depth, zi, and stable boundary layer height from March through October of 1998 are derived from a 915-MHz boundary layer profiling radar and CO2 mixing ratio measured from a 447-m tower in northern ...
Long-Term Carbon Dioxide Fluxes from a Very Tall Tower in a Northern Forest: Flux Measurement Methodology
Publisher: American Meteorological Society
Abstract: Methodology for determining fluxes of CO2 and H2O vapor with the eddy-covariance method using data from instruments on a 447-m tower in the forest of northern Wisconsin is addressed. The primary goal of this study is the ...
Application of a Differential Fuel-Cell Analyzer for Measuring Atmospheric Oxygen Variations
Publisher: American Meteorological Society
Abstract: A commercially available differential fuel-cell analyzer has been adapted to make field-based ppm-level measurements of atmospheric O2 variations. With the implementation of rapid calibrations and active pressure and flow ...
Transport of Carbon Dioxide in the Presence of Storm Systems over a Northern Wisconsin Forest
Publisher: American Meteorological Society
Abstract: Mixing ratios of CO2 often change abruptly in the presence of inclement weather and low pressure systems. Water vapor mixing ratio, temperature, wind speed, and wind direction data are used to infer that the abrupt changes ...
