Atmospheric Boundary Layer Measurements in South-Central Kansas

摘要

The Atmospheric Boundary Layer Experiments (ABLE) (http://www.atmos.anl.gov/ABLE/) facility was established in 1997 within the Walnut River Watershed in south-central Kansas (USA), east of the city of Wichita, to support studies in boundary layer meteorology, hydrology, ecology, and atmospheric chemistry. Instrumentation includes 3 radar wind profilers (with radio acoustic sounding systems), 3 Doppler acoustic sounders, five automated surface weather stations, 2 eddy correlation flux measurement systems, 1 energy balance Bowen ratio system, and 28 recording rain gauges. Atmospheric radiation and soil temperature, moisture, and heat flow are measured at 2 locations. Continuously collected data are available on the ABLE web site in near-real-time and archived forms. The three areas of current primary emphasis are (1) the air-surface exchange of carbon dioxide, in support of AmeriFlux studies of terrestrial carbon balance; (2) the water budget and its seasonal and event variability at multiple spatial scales within the watershed; and (3) support for the Cooperative Atmosphere-Surface Exchange Study (CASES) in investigations of mesoscale meteorology, hydrology, climate, and chemistry processes and their linkages.
