Climate Change

• Climate changes of the past 1 000 and 10 000 years in the Canadian Arctic by K. Gajewski
  An expanded summary of a presentation given to the Commission on Geosciences, Environment and resources on 15 July 1999, Ottawa.

Climate Maps

• Analysis of the July Arctic front from surface wind streamlines with front positions by year and maps of atmopsheric parameters to analyse a frontal boundary (M. Ladd)
  
• Frequency of July maximum temperatures for selected Environment Canada climate stations (M. Ladd)
  
• Frequency of July NDVI anomalies (maps and table of values) in relation to the July Arctic front position by year (M. Ladd)
  
• Mean July wind streamline maps for 1958-2002 from ERA-40 reanalysis and long term mean monthly wind streamline maps (M. Ladd)
• Mean July streamline maps for 1958 to 2002 derived from ERA-40 reanalysis (M. Ladd)
• Mean 1958-2002 streamline maps for all months derived from ERA-40 reanalysis (M. Ladd)

Modern Pollen-Vegetation Relations

• Towards Improved Paleoclimate Estimates: The modern pollen vegetation relation by M. Sawada , K. Gajewski and P. Richard
  Describes first attempts to approximate pollen-samples view of surrounding vegetation using various distance weighting techniques including inverse distance, inverse-distance squared, dispersal weigthing based on diffussion from a ground level source, anisotropic source areas based on dominant wind direciton and unweighted scenarios with results.

Spatial Statistics

• Global Spatial Autocorrelation Indices - Moran's I, Geary's C and the General Cross-Product Statistic By M. Sawada
  Describes and discusses with worked examples how spatial autocorrelation works and uses Rooks Case v.0.9 freeware

Cellular Automata

• Cellular Automata "Mini-Models": Emergent Spatial Structure in Vegetation Succession by D.E. Atkinson, M. Sawada and K. Gajewski
  Definition of Cellular Automata, History, Application and Results of our model CA 2D.

Data Logger Programming

• Datalogger Programming and Practice with the Campbell 21x by M. Sawada
  Gives a detailed overview with a fictitous objective for programming a Campbell datalogger using a UDB01 snow sensor, thermocouples, tipping bucket raingauge, potentiometer and battery life. Includes equations and conversion etc.

Technical Solutions Series

• Climate data methods and analysis (M. Ladd): Describes methods for (1) creating a temperature anomaly map in ArcGIS from ERA-40 reanalysis data, (2) creating a wind direction contour map in ArcGIS using WindSpeedTools extension and reanalysis data in NetCDF format, (3) creating a long term mean temperature map in ArcGIS using the North American Regional Reanalysis 2m temperature data, (4) reading GRIB data into the Grid Analysis and Display System (GRADS) and (5) converting GRIB data for use in ArcGIS using TKdegrib software.
  
• Importing and displaying geological maps from the Geological Survey of Canada "Geological Map of Canada" (Map D1860A ver. 1.0, Jan 97 on CD-ROM) using IDRISI GIS for Windows ver. 2 by D.E. Atkinson
  Describes the process of importing into IDRISI GIS the maps found on the CD-ROM entitled, "Geological Map of Canada", issued by the Geological Survey of Canada. Tasks discussed include importing the maps, reprojection, conversion from vector to raster, colourizing, linking to an attribute database and superposition of a vector coastline map for reference.
