record_short

Measurements meta data as recorded on the field

datasets

Toolbox to process raw data from closed loop flux chamber (or tent)
setups into ecosystem gas fluxes usable for analysis. It goes from a
data frame of gas concentration over time (which can contain several
measurements) and a meta data file indicating which measurement was done
when, to a data frame of ecosystem gas fluxes including quality diagnostics.
Organized with one function per step, maximizing user flexibility and backwards
compatibility. Different models to estimate the fluxes from the raw data are
available: exponential as described in
Zhao et al (2018) <doi:10.1016/j.agrformet.2018.08.022>, exponential as described in
Hutchinson and Mosier (1981) <doi:10.2136/sssaj1981.03615995004500020017x>,
quadratic, and linear. Other functions include quality assessment,
plotting for visual check, calculation of fluxes based on the setup
specific parameters (chamber size, plot area, ...), gross primary production
and transpiration rate calculation, and light response curves.
