High-Resolution Meteorological Monitoring over the National Capital Region: Data from the DCNet Network at the US Department of Commerce Herbert C. Hoover Building Station

This report provides a description and a brief analysis of both mean and turbulence observations of the DCNet HCHB Hoover-North monitoring station for the period 2017-2019. Comparison of mean wind and temperature observations against regional NOAA National Weather Service monitoring sites is provided as reference for the HCHB observations. Total kinetic energy (TKE) is calculated from the horizontal and vertical turbulence statistics u’2, v’2, w’2. Turbulence measurements are compared to well-accepted atmospheric boundary-layer values proposed by Garratt (1992). Furthermore, the mean stability term (z/L) is calculated based on Monin-Obukhov Similarity Theory. Overall, this data analysis is an important step to providing a foundation for the use of DCNet research network in order to improve the formulations of key variables controlling dispersion model calculations in urban areas, such as Washington, D.C.
