Notes:

• You do not need to set the date/time info for the overlay if you want the same date/time data as the base map.
• Data were extracted from the 1950-2008 NCEP/NCAR Reanalysis CDROM series.
• The global data are available:
  • Temperature for 850,500, and 200mb
  • Geopetential Height for 1000, 850, 700, 500, 300, and 200mb
  • Horizontal Winds for 850, 500, and 200mb
  • Vertical Velocity for 500mb
  • Relative Humidity for 850 and 500mb
• Other data parametersi, which can be derived from the above data fields, are also availanle.
