NAME

   amsu.amsua.limbcorrection.AMSUALimbCorrection.java 

PURPOSE

   To adjust a satellite observation to nadir sensor incidence angle (limb correction).

DESCRIPTION

   This class is the entry point for limb correction both for level 1c processing 
   (if limb correction flag is set) and level 3 processing (if limb correction 
    flag is set). It specifies current limb correction scheme used, loads coefficients
    from files, and adjusts satellite observations to nadir.

REVISION HISTORY

   05/20/2013 Initial Version prepared for NCDC
   10/05/2010 Tried other limb correction methods 2 & 3. 
                Goldberg 2001 is still be best so far.
   03/05/2010 Initial version developed for the 2010 Workshop on Climate Data Records
              from Satellite Microwave Radiometry.
