Radiometer Data

* Data collected by Bath University's 93 GHz radiometer during the CLARE'98 campaign 
  has been used to produce estimates of the total liquid water path above Chilbolton. 
 
* Profiles of water vapour and air temperature from the ECMWF model data have been 
  used to estimate the contribution that atmospheric gases make to the measured 
  brightness temperature at 93 GHz.  
 
* It has been assumed that when clouds are present, their temperature is ~283K.   
 
* Estimates of liquid water have been made by using the two possible extremes of the 
  mean absorbing temperature of the atmosphere (Tm).  The resulting extremes of liquid 
  water path are plotted as different colours.
