PURPOSE

   Check AMSU montly gridded data for months with too little data
   Determines which months to use in merge and returns and array, months_to_use,
   that is used in subsequent steps to choose which satellite months to include

DESCRIPTION

 This routine checks the AMSU GRPT data for months with too little data
 
 Inputs:
   num_arr  (should be a (144,72,num_months,num_sats) array of number of obs per grid cell
   sats_to_use (num_AMSUs) array of integers  0 to ignore this satellite, 1, to use it
   num_thres is the threshold for the mean number of observations to be good data.
   months_to_use_mask is a (num_months, num_sats) array of integers:  
               -1 to exclude
                0 to use threshold to determine use (the usual case)
                1 to use even if threshold fails
 Output:
   months_to_use  (num_months,num_sats) array of months to use in the merge.  1 means use,0 means don't use

NAME

   grpt_merge_AMSU_only_3_3.pro

PURPOSE

   Top-level program that performs adjustments to AMSU monthyl gridded data, and then 
   merges the data together into a single AMSU derived brightness temperature dataset

DESCRIPTION

   Reads gridded monthly averages from individual files.  We call these L2C files.
   Calculates and applies target factors using singluar value decomposition
   Calculates and applies latitude dependendent offsets using singlular value decompostion
   Scene temeprature factors are set to zero for AMSU
   Merges data from the chosen set of satellite together using equal weighting
   Writes the results to a netcdf file.  We call these files L3.
