Tapajos K67 tropical forest seasonal flux tower data

Seasonal (16-day) eddy covariance measurements that include water, carbon,
and energy flux, radiation, canopy temperature, humidity, and ancillary
calculations such as evaporation, transpiration, and leaf area
index.  Data was collected at the Tapajós National Forest,
Santarem K67 (BR-Sa1), a tropical primary forest (2.857°S,
54.959°W).  Measurements correspond to the periods: April 2001 -
January 2006, July 2008 - July 2012, and January 2015 - July
2020.  The 16-day fluxes and meteorological data were obtained
from an average daily cycle based on hourly observations. As a result, we
refrain from assigning greater significance to specific hours when the
fluxes tend to be complete, and vice versa (for instance, in cases of
missing flux values due to afternoon rainfall events). Daytime values were
selected as above a 5 W m-2 top of the atmosphere radiation (TOA; W m-2)
and labeled as LEdaytime in the case of latent heat flux (LE), Hdaytime
for sensible heat flux (H), and so on.
