Carbon Exchange Data - Dwarf Cypress Sampling Location (Greater Everglades)

Carbon dioxide exchange with the atmosphere over forested subtropical wetlands, such as cypress strands and pine forests in the Greater Everglades, is largely unknown. Here we report a first step in characterizing this atmospheric-ecosystem carbon (C) exchange, as measured with eddy covariance methods at three locations (Cypress Swamp, Dwarf Cypress and Pine Upland) for one year. This data set is an Excel file containing data for the Dwarf Cypress sampling location. It includes the following data sheets: \r\n - working_stage - raw data from pressure transducer. Water distances above and below land-surface are computed in this worksheet.\r\n - raw_weather - raw data for wind direction, wind gust, incoming solar radiation, soil heat flux, net radiation, air temperature, relative humidity, temperature of air, water and soil, and volumetric water content.\r\n - work_weather - mean 30-minute mean calculations for data in raw_weather. Time is synced for weather and eddy covariance data. Wind speed correction for net radiation is performed on this worksheet.\r\n - GHG - raw data from EddyPro (processes 10-Hz GHG files into 30-minute mean GHG fluxes). Includes sensible heat, latent heat, CH4 flux, NEE, air properties, wind velocities, QAQC checks such as Ustar, and measurement source area calculations.\r\n - GHG_working - contains gapfilling results for latent heat, sensible heat, NEE, CH4. Also performs daily and monthly NEE, Re, GEE, and WUE computations.\r\n - LUT - Gap-filling results from the Reichstein et al. (2005) look-up table.\r\n - CH4 - daily observed and simulated (equation 2) molar methane fluxes. Statistical estimates of model fit. Plot of observed and simulated results.\r\n - remove_NEE - removes 1, 5, 10, and 20% of observed NEE fluxes for gap-filling uncertainty calculation.\r\n - RU - results from random uncertainty estimates based on Finkelstein and Sims (2001).\r\n - ustar - calculation of the U* filter threshold.\r\n - EVI_ NDVI - contains EVI data from MODIS for comparison with GEE.\r\n - weather_fig - plots of temperature, water levels and surface energy fluxes in the paper.\r\n - DATA - CR1000 output for soil, air and water temperature, net radiation, air temperature, relative humidity, photosynthetically active radiation. Conversions of pressure transducer water depths into distances above and below land-surface.\r\n - DAVE_Rn - CNR-01 data including incoming and outgoing short and longwave radiation. Calculation of net radiation and albedo.\r\n - Baro - Barometric pressure data.
