Dataset Abstract

	Above canopy measurements of carbon dioxide fluxes and sensible and latent heating were obtained with an open path eddy covariance system positioned on the tower at 26-m. Additionally, measurements of solar irradiance, wind speed, air temperature and humidity were made every half hour.

Methods

	Sampling Description 

		Fluxes are determined as half hour averages of 10 Hz covariance measurements of vertical wind speed and the scalar of interest (e.g. CO2).


	Method Step 

		Description 

			The eddy covariance method (Dennis Baldocchi at Cal Berkeley)

		Instrumentation

			Flux tower and a listing of additional instrumentation can be found at http://www.people.virginia.edu/%7Ejf6s/pace/VFRFInstruments.html.


		Quality Control 

			Dataset is inspected by PI for QA/QC; standard validation checks for negative numbers, graphs to detect potential outliers .

Data Submission Notes

	PLEASE NOTE: THIS FILE WILL REPLACE ST_PP_BARR_006 AND ST_PP_BARR_006.V1 and ST_PP_BARR_006.V2. 1. All quantities are half hour averages, and the time provided is the starting period. So, for time = 0, data is averaged from 0:00 to 0:30 hours. 2. During some periods, rain events produce invalid fluxes (for sensible and latent heat and CO2 flux). I replaced these values with zeros whenever possible. 3. Sometimes the air temperature measurement at 35 feet produces some spikes. I have not changed or eliminated these values because I usually take care of that in post-processing programs. 4. The quantum sensor that provides incoming photosynthetically active irradiance is often shaded sometime during the day because my boom on the tower is too short. I recommend just using solar irradiance to estimate this quantity. However, incoming photosynthetically active irradiance could still be useful if the data is properly filtered (but it would be a pain). 5. As you can imagine, it is not easy to really clean up this data set. I would just encourage someone using the data to take a close look at the diurnal profiles of any variable before proceeding.


Information Management Notes

	This is a short-term primary production dataset. This dataset replaces all previous versions of ST_PP_Barr_006, ST_PP_Barr_006.v1 and ST_PP_Barr_006.v2. The FCE program is discontinuing its practice of versioning data as of March 2013.
