Hi Fernando, The half degree GFS, for example, does indeed supply both the Haines and Field Capacity indices and are available in the IDV default catalog. For the GFS Half Degree Forecast, see - 2d grid > Soil > Field Capacity Index - 2d grid > Fire Weather > Haines Index However, these fields are not derived within the IDV. They are supplied by the GFS model. In order, to discover how these fields are derived within the GFS you would have to do some research starting at NOAA NCEP http://www.ncep.noaa.gov/ where the GFS model is generated. Related to this topic, you can derive your own quantities in the IDV via Jython formulas.
