------------------------------DATA & FILE OVERVIEW-----------------------------
This dataset contains the 30-min averaged observations measured at Duke Forest 
and flux results calculated using the eddy covariance method for the article 
"Spatial heterogeneity of ammonia fluxes in a deciduous forest and adjacent 
grassland".

The dataset contains 3 files.

Files:
1. flux_results_forest.csv
2. flux_results_grassland.csv
3. README.txt

-----------------------------------File 1-2------------------------------------
These files are the 30-min results of fluxes, micrometeorology and other relevant 
parameters for forest and grassland, respectively.

Each of the file contains 59 columns. The first row lists the variable names and 
the second row lists the units. Data start from the third row.

"-9999" stands for missing or invalid data.

-----------------------------------File 3-------------------------------------
File 3 is this README file.
