Data are available as zipped Excel® Spreadsheets (.zip). Details for each data sheet contained in each spreadsheet are seen below.
Dwarf Cypress:
 working_stage  raw data from pressure transducer. Water distances above and below landsurface are computed in this worksheet.
 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.
 work_weather  mean 30minute 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.
