(1) bin2nc.ncl

    read the equal ISCCP binaries
    use 'dsread' to create 2.5 grid
    create netCDF ISCCP.yyyymm.nc files


(2) (optional)
    most efficient is to:
    ncrcat ISCCP.*.nc ISCCP.19832000.nc   

    (this failed once so I did the following)
    ncrcat ISCCP.198*.nc isccp.19831989.nc   
    ncrcat ISCCP.199*.nc isccp.19901999.nc   
    ncrcat ISCCP.200*.nc isccp.20002000.nc   
    ncrcat isccp.19831989.nc isccp.19901999.nc isccp.20002000.nc \
           isccp.nc
    'rm' isccp.19831989.nc
    'rm' isccp.19901999.nc
    'rm' isccp.20002000.nc

    in T42 dir
    ncrcat ISCCP.[12]*.T42.nc isccp.T42.nc

    in T63 dir
    ncrcat ISCCP.[12]*.T63.nc isccp.T63.nc


(3) gridInterpolate.ncl

    interpolat the 2.5 grids to T42/T63


(4) gridCompare.ncl

    Read data from the 2.5, T42 and T63 grids

    select variables

    plot global view at specified time(s)

    plot a time series


(5) gridTimeSeries.ncl

    create time series of specified variables
    (a) at specified grid point; (b) global averages


(6) gridClm.ncl

    climatologies of specified variables.
    (a) use gridClm.ncl on 
        isccp.nc, isccp.T42.nc, isccp.T63.nc
    or
    (b) use gridClm.ncl_addfiles on 
        ISCCP.[12]*.nc, ISCCP.[12]*.T42.nc, ISCCP.[12]*.T63.nc

    more efficient to use (a)
