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.

While substantial efforts are made to ensure the accuracy of data and associated documentation, complete accuracy of data sets cannot be guaranteed. All data are made available "as is." The Data User should be aware, however, that data are updated periodically and it is the responsibility of the Data User to check for new versions of the data. The data authors and the repository where these data were obtained shall not be liable for damages resulting from any use or misinterpretation of the data. Thank you.

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.
