Description of PEcAn
The Predictive Ecosystem Analyzer (PEcAn) is a scientific workflow management tool that is designed to simplify the management of model parameterization, execution, and analysis. The goal of PEcAn is to streamline the interaction between data and models, and to improve the efficacy of scientific investigation. PEcAn is an open source utility that encapsulates:
acquisition of meteorological inputs
synthesis of physiological trait data as the posterior distribution of a Bayesian meta-analysis
sampling trait meta-analysis posterior distributions to parameterize ensembles of ED2 and other ecophysiological models
probabilistic forecasts
postprocessing to constrain forecasts and model parameters with field, meterological, eddy flux, and spectral data, and
provenance tracking
PECAn integrates available data into ecological forecasts by running ensembles of a terrestrial ecosystem model that is parameterized by the posterior distribution from a meta-analysis of available plant trait data. These trait data are assembled from field research and primary literature, and are stored in a PostgreSQL database. Current development focused on biofuel crops uses BETYdb. In addition to generating forecasts that reflect available data, PEcAn quantifies the contribution of each parameter to model uncertainty. This information informs targeted data collection and synthesis efforts that most efficiently reduce forecast uncertainty.
Current development is focused on developing PEcAn into a real-time data assimilation and forecasting system. This system will provide a detailed analysis of the past and present ecosystem functioning that seamlessly transitions into forecasts.

Generic function to convert model output from model-specific format to a common PEcAn format. This function uses MsTMIP variables except that units of (kg m-2 d-1) are converted to kg ha-1 y-1. Currently this function converts Carbon fluxes: GPP, NPP, NEE, TotalResp, AutoResp, HeteroResp, DOC_flux, Fire_flux, and Stem (Stem is specific to the BioCro model) and Water fluxes: Evaporation (Evap), Transpiration (TVeg), surface runoff (Qs), subsurface runoff (Qsb), and rainfall (Rainf).
For more details, see the MsTMIP variables documentation.
If dataframe = FALSE, a vector of output variables. If
dataframe = TRUE, a data.frame of output variables with
POSIXct timestamps added (posix column). The posix column
is in seconds after January 1 of start.year, or 1970 if
start.year is not provided.

A lookup table giving standard names, units and descriptions for variables in PEcAn input/output files.
Originally based on the MsTMIP standards,
with additions to accomodate a wider range of model inputs and outputs.
The standard_vars table replaces both mstmip_vars and mstmip_local,
both of which are now deprecated.
standard_varsstandard_vars
data frame, all columns character
Short name suitable for programming with
Name used in the NetCDF CF metadata conventions
Standard units for this variable. Do not call variables by these names if they are in different units.
See ud_convert for conversions to and from non-standard units
Human-readable variable name, suitable for e.g. axis labels
What kind of variable is it? (Carbon pool, N flux, dimension, input driver, etc)
Storage type (character, integer, etc)
Dimensions across which is this variable allowed to vary. Dimension names are themselves standard vars and must be present in the table with category "Dimension"
Further details. For composite measures, list the variables it is calculated from
Records the progress of a PEcAn workflow by writing statuses and timestamps to a STATUS file. Use these each time a module starts, finishes, or is skipped.
status.start(name, file = NULL) status.end(status = "DONE", file = NULL) status.skip(name, file = NULL) status.check(name, file = NULL)status.start(name, file = NULL) status.end(status = "DONE", file = NULL) status.skip(name, file = NULL) status.check(name, file = NULL)
name |
one-word description of the module being checked or recorded, e.g. "TRAIT", "MODEL", "ENSEMBLE" |
file |
path to status file.
If NULL, taken from |
status |
one-word summary of the module result, e.g. "DONE", "ERROR" |
All of these functions write to or read from a STATUS file in your run's
output directory. If the file is not specified in the call, they will look
for a settings object in the global environment and use
<settings$outdir>/STATUS if possible.
Since the status functions may be called inside error-handling routines,
it's important that they not produce new errors of their own. Therefore
if the output file doesn't exist or is not writable, rather than complain
the writer functions (status.start, status.end, status.skip) will
print to the console and status.check will simply return 0.
For status.start, status.end, and status.skip: NULL, invisibly
For status.check, an integer:
0 if module not run, 1 if done, -1 if error
status.start(): Record module start time
status.end(): Record module completion time and status
status.skip(): Record that module was skipped
status.check(): Look up module status from file

Provides a zero bounded density estimate of a parameter.
Kernel Density Estimation used by the density function will cause problems
at the left hand end because it will put some weight on negative values.
One useful approach is to transform to logs, estimate the density using KDE, and then transform back.
