Susquehanna Shale Hills CZO - Cole Farm Surface Flux

LI-COR LI 7500 measures CO2 and water vapor concentration at 10Hz time resolution. Campbell Scientific CSAT3 gives 3D wind speed and air temperature at 10Hz rate. CO2, sensible heat, latent heat fluxes were calculated every 30min based on the above measurements (time stamp shows the end of the 30min window). Wind speed and air temperature were measured with a Campbell Scientific CSAT3 Three-Dimensional Sonic Anemometer, http://www.campbellsci.com. CO2 and water vapor concentration measured with a LI-COR LI-7500 CO2/H2O Analyzer, http://www.licor.com. Flux data were processed, and quality controlled with the method suggested by Vickers and Mahrt, 1997 (including remove the spikes, dropouts, etc.) .

Tower was located in swale between two fields along a spring.
