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 .

	These data are classified as 'Type II' whereby original FCE LTER experimental data collected by individual FCE researchers to be released to restricted audiences according to terms specified by the owners of the data. Type II data are considered to be exceptional and should be rare in occurrence. The justification for exceptions must be well documented and approved by the lead PI and Site Data Manager. Some examples of Type II data restrictions may include: locations of rare or endangered species, data that are covered under prior licensing or copyright (e.g., SPOT satellite data), or covered by the Human Subjects Act, Student Dissertation data and those data related to the FCE LTER Program but not funded by the National Science Foundation (NSF) under LTER grants #DEB-9910514, and # DBI-0620409. Researchers that make use of Type II Data may be subject to additional restrictions to protect any applicable commercial or confidentiality interests. All publications based on this dataset must cite the data Contributor, the Florida Coastal Everglades Long-Term Ecological Research (LTER) Program and that this material is based upon work supported by the National Science Foundation through the Florida Coastal Everglades Long-Term Ecological Research program under Cooperative Agreements #DEB-1237517, #DBI-0620409, and #DEB-9910514.

Maintenance

	This is a long-term primary production dataset and subsequent data will be appended. This dataset replaces all previous versions of LT_PP_Barr_001, LT_PP_Barr_002 and LT_PP_Barr_003 as the dataset were combined into LT_PP_Barr_001 to facilitate data usability. The FCE program is discontinuing its practice of versioning data as of March 2013.

Data Submission Notes

	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 long-term primary production dataset and subsequent data will be appended. This dataset replaces all previous versions of LT_PP_Barr_001, LT_PP_Barr_002 and LT_PP_Barr_003 as the dataset were combined into LT_PP_Barr_001 to facilitate data usability. The FCE program is discontinuing its practice of versioning data as of March 2013. Please Note:  LT_PP_Barr_001, LT_PP_Barr_002 and LT_PP_Barr_003 have been combined into a new file called LT_PP_Barr_001 in order to facilitate data downloads and usability.  LT_PP_Barr_002 and LT_PP_Barr_003 are most alike in terms of measurement parameters where as LT_PP_Barr_001 included some additional measurements and omitted others.  LT_PP_Barr_001 included Wind Speed (ws_wvt), Total photosynthetically active irradiance (parTot), Total photosynthetically active irradiance (parTot2), Soil Water Potential (PS1-PS8) and Precipitation (Rain2) whereas LT_PP_Barr_002 and LT_PP_Barr_003 do NOT include these measurements.  LT_PP_Barr_002 and LT_PP_Barr_003 DO include Average CO2 Concentration (co2_avg), Average H2O Concentration (h2o_avg), Average Air Temperature (T_avg) and Average Barometric Pressure (P_avg) and LT_PP_Barr_001 does NOT have these measurements.
