Carbon flux and gross primary production of a scrub of Mexico

Vegetation fixes C in its biomass through photosynthesis or might release
it into the atmosphere through respiration. Measurements of these fluxes
would help us to understand ecosystem functioning. This data is related to
carbon flux (NEE) colected with the eddy covariance technique (EC_Data).
The NEE is the balance between gross primary production (GPP) and
ecosystem respiration (Reco) both calculated using the recent R package
Reddyproc (Code Reddyproc). The database also include estimates
of GPP of MOD17A2H product of MODIS Satellite for four pixels of a site
with scrub vegetation in Mexico (GPP_MODIS). The programming code include
the pre-procecing of NEE and the Theil-Sen and Linear model to describe
the relationship between GPP of EC and GPP of MODIS (Code Theil-Sen).
