Supplemental Information

Relationship to other Datasets: The layer is derived using ESOCLIM and DEM100. For a given area one can expect high correlations between RAIN<month> and DEM100 Related Documents: None ESOCLIM documentation (CLIM_GRD.DOC) ANUCLIM Users Guide

Missing Data

Complete for the state. Complete for all Victorian Catchment Management Authority (CMA's) areas. 

Attribute Quality

Normally claimed to be within 5% of the actual value. This is based on a generalised cross-validation algorithm which carries out the original interpolation without each point in turn, and compares the interpolated value at that point with the observed value. 

Positional Accuracy

Precision: 10-100m Determination: Based on the input map scale for the data resampled to 100m from VICMAP_ELEVATION_DTM_20M 

Lineage

Description

ArcInfo Workstation converts a GRID to an ascii file suitable for input to ANUCLIM and runs the program. A number of small, customised programs are used in this process. Output files are large (160 bytes/cell), prohibiting estimation of multiple variables for large grids in a single pass. ArcGIS Toolbox converts ANUCLIM output files to ARC/INFO grids, using standard names for the output grids. Output grids are maintained as floating. 

Statement

Dataset Source: The dataset is an output from the ANUCLIM program, which interrogates pre-existing interpolated surfaces using, as input variables, latitude, longitude, and elevation. DEM20 is used to estimate elevation. The original surfaces are interpolations of climate variables using minimum curvature multi-dimensional splining algorithms developed by Dr. Mike Hutchinson of the Centre for Resource and Environmental Studies (CRES) ANU. Further details regarding the derivation process can be obtained from ANUCLIM Users Guide. ANUCLIM is licenced software, CRES may lay some claim to datasets derived using ANUCLIM.
