Features
  • Peer-reviewed by Chinese experts
  • Incorporates topographic effects on temperature
  • Includes coastal and lake effects on temperature
  • Accounts for temperature inversions on coasts and in inland valleys
  • Uses upper-air temperature data to capture high-elevation patterns
  • Consistent treatment and spatial quality control of station data
  • "Universal" geographic (latitude/longitude) projection allows conversion to any other coordinate system
  • Data format allows for easy import into ESRI's GIS products, as well as MAPINFO and Intergraph's GeoMedia

Data used in analysis

  • 2,450 Stations from the National Meteorological Center and other sources
  • 166 Upper-air "stations" from the Gridded Global Upper-Air Statistics dataset
