The Coniferous Forest Biome is committing itself to the synthesis of the collected data. The computer programs documented in the following three internal reports have had a very useful track record in the synthesis of data and the computer implementation of models.
RICHER is a sophisticated interpolation routine which allows the user to
generate data for points he does not have. The following activities
are at best marginally legitimate.
A. Regenerate a dataset at a different step size (monthly points
instead' of bimonthly)
B. Estimate, missing data due to equipment failure
C....
PLOTCAL is a subroutine package to aid in organizing and attaching Calcomp graphics to existing programs and simulations. PLOTCAL is self-contained, requiring additional card input and a binary data file from the generating program.
SIMCOMP is a computer programming system which is designed to aid biologists with a limited knowledge of FORTRAN programming to design and execute compartment-flow simulations. The system is designed to minimize the programming overhead required by any computer language while maintaining
sufficient flexibility of FORTRAN. This flexibility does allow interfacing...
A convenient method of portraying functions of n dimensions to aid modeling
is needed. Unfortunately, visual representations are limited to only
two independent variables. ISO was written to partially meet the demands
of two-independent-variable graphics.
Much effort can be saved by having well-documented field notebooks and field sheets. ITABLE will produce notebook pages filling in the collector's name, dates, stations, and depths.
Biome investigators are well skilled in collecting and recording numbers.
The investigators continue through description of the notebook data.
Some investigators encounter much trouble in getting the data our of
their notebooks and Interchanged among people in a usable format. This
paper describes an effort to automate the calculations done...
The Coniferous Forest Biome has access to several strip chart recorders but is definitely limited with respect to data-logging equipment. The methodology reported in this paper interfaces the common strip chart with the Coniferous Forest Biome Information bank storage system by
converting the strip chart data to card image data...
A steady-state model designed especially for analysis of gas exchange studies of terrestrial net photosynthesis is discussed. The model expresses net photosynthesis as a function of light, temperature, CO₂ concentration, stomatal resistance, and other factors. The parameters of the model are
estimated from data by nonlinear least-squares. The data set...
Research activities in the post-IBP phase of the Biome program prior to July 1975 were reported in Internal Report 162. Summaries of research and synthesis activities from July 1975 to August 1976 are presented here. The reports are arranged in the following order: Analysis of individual terrestrial ecosystems, which has...
