The outputstream.csv is created and saved to the
output directory when Hector is executed from the command
line or Xcode (but not when running from R; R users should use
fetchvars).
Output stream categories:
An important note about time: The outputstream code currently writes the end date of the current timestep in the outputstream.csv file; e.g., when we’re running 1 January 1745 - 31 December 1745, what gets written is “1746”. This is not intuitive (most people think of “1746” denoting January 1-December 31) but numerically correct: the date is 1746.0, i.e. midnight on December 31 1745. A consequence is that carbon fluxes logged at this timepoint are effectively for the calendar year 1745 (1745-01-01 to 1745-12-31).
The first line of this file is a timestamp and version number line, and should be skipped by any CSV-reading code.
The variables that appear in the outputstream table include:
