Main new features and enhancements
 |
Runs faster. The main surface
fitting algorithm in BIOCLIM, ESOCLIM and GROCLIM has been rewritten.
Run times for these programs are now around one half to one third of
the times for ANUCLIM 5.0 |
 |
Outlier identification for
bioclim frequency plots. BIOCLIM has two new features that enable
you to spot suspicious data points in your input data. This first is
the 'parameter extremes' list which lists each site that appears as
either a maximum or minimum value on one or more parameters. The second
is the labelling of outlier points on the cumulative frequency plots. |
 |
Export to spreadsheet from
.bio file A new option on the bioclim menu translates a .bio file
into a .csv (comma separated values) text file that can be read into
spreadsheets such as Excel or Gnumeric. |
 |
Skips header, footer and other
junk lines when doing free format read. When reading free-format
text files in esoclim, bioclim or groclim, any line that cannot be
interpreted as a site is ignored. This allows you to keep header, footer
or comment lines in the text file without introducing errors. A count
of the lines that are skipped is reported in the log file. |
Full details of changes
There are also a few bug fixes and other minor enhancements in ANUCLIM 5.1. They
are described here.
What does ANUCLIM do?
ANUCLIM produces estimates of monthly mean climate variables, bioclimatic parameters,
and indices relating to crop growth. The main components of the package are ESOCLIM,
BIOCLIM and GROCLIM. It has been developed at CRES and consists of
- ESOCLIM for calculating values of monthly mean climate
- BIOCLIM and BIOMAP, the bioclimatic prediction system
- GROCLIM, a simple generalised crop model
- A graphical user interface which drives the whole thing.
It uses mathematical descriptions of the way a set of climate variables change
across a region (known as surfaces) in order to estimate those climate
variables, or parameters derived from them, at user specified points within the
region.
The basis for combining all the programs into the one package is their
complete reliance on climate surface coefficient files as created by the
ANUSPLIN package (Hutchinson 1991). If these files do not exist for the
country of interest, then the first step, before ANUCLIM can be used, is
to create them.
For more information, see the ANUCLIM
user's guide .
What input data and extra software do I need?
Data: Depending on the type of analysis you want to do, you will need
either or both...
- A list of sites, each site accurately describing its position and
elevation.
- A Digital Elevation Model (DEM) for your area of study.
Software:
- A Geographic Information System (GIS) is highly desirable.
- You may need the ANUSPLIN package to develop your own climate surfaces
if you are outside Australia.
See the ANUCLIM user's guide for
details.

Patches
From time to time we find bugs in ANUCLIM, and sometimes the fixes or workarounds
for these problems can be downloaded from the CRES web site as patches. The full
set of patches can be found here.
Supported platforms
ANUCLIM 5.1 is available for
- Windows 95, 98, 2000, NT (on Intel hardware)
- Sun Solaris (on SPARC hardware)
- Silicon Graphics Irix (on MIPS-3 or later hardware)
- Compaq Digital Unix (on Alpha hardware)
We hope to support Linux (on x86 hardware) soon.
