Get the most accurate global water vapor image available for a given timeframe.
Initially GETWATER was written to just access the TOVS dataset. However, since NASA Goddard was grossly negligent in making TOVS available in a near-real-time timeframe, another water vapor data source was identified (NCEP). GETWATER now needs to be modified so that it will:get an NCEP image if available for the day of interest otherwise get a TOVS image for the day of interest otherwise get a TOVS climatology image for the day of interest
Attempt to get an NCEP image for the designated date and time (GETNCEP). If failure, attempt to get a TOVS image for the designated date and direction (ascending/descending) (GETTOVS). If failure, attempt to get a TOVS climatology image for the designated date and direction (ascending/descending) (GETTOVS).
Get an NCEP global water vapor image if available
