Graphics generation with Vizmet

The radiometer display on the previous web page was generated by the Vizmet program.  Vizmet generates plots based upon time histories of surface temperature, pressure, and humidity, vertical pointed infrared radiometer measured cloud base temperature, and the microwave radiometer's neural net output of temperature, humidity, and liquid water profiles.  For the NASA Glenn Icing Remote Sensing project plots, Vizmet further refines the neural net profile data by applying the following threshold values:


Cloud Top- Cloud top limit temperature:   253K
                    Relative Humidity threshold:  70%

Cloud Base- Ignore Infrared radiometer data
                     Relative Humidity threshold:  80%

Max values-  RH: 100%
                      Liq:  3 g/m³
