Cloud Clearing data format 
                
1) There will be three binary files for each AIRS cloud clearing output.
     cloudyFOV.bin       --- Original AIRS FOV information.
     cloud_cleared.bin   --- Cloud cleared information.
                             This contains both 'clear' and 'cloud cleared succesfull'
                             FOV information .
     clearNeighbor.bin   --- Clear Neighbor (if exists) FOV information.
                             (this is for cloud clearing performance comparison.)

2) These data are saved in IEEE floating point with big-endian byte ordering.
   Special or missing value is -999.

3) Each data are saved in the dimensions of:
   [rec_length, AIRS_across_pixels, AIRS_scanlines], and usually 
   the matrix size is (2400, 90, 135).

4) data structures are as follow:
   (   1~2378, :, :)  -- AIRS spectral brightness temperature [unit: K]
   (     2379, :, :)  -- FOV latitude
   (     2380, :, :)  -- FOV longitude
   (     2381, :, :)  --   9 
   (     2382, :, :)  -- FOV scan angle
   (     2383, :, :)  -- FOV topog
   (2384~2400, :, :)  -- Reserved for future use

5) Sample Matlab script to read these data is:
   "cloud_clear_reader.m"
