5.0  Quality Control Information


     These data were quality assured and quality controlled at the University
     of Minnesota, UCAR/JOSS has not changed these data in any way, and has 
     conducted no quality control on this data set.

        Reasons for missing or bad data-

                1.  274, 1997 to 296, 1997- Equipment used to measure 7-12 not installed.
                        Incoming solar radiation data supplied by LI200S LI-COR Silicon
                        Pyranometer at existing weather station.
                2.  296, 1997 to 310, 1997- Datalogger command to interogate Geonor precipitation
                        gauge is incorrect.
                3.  296, 1997 to 27, 1998- Incorrect voltage range used by dataloger for
                        measuring Eppley Pyrgeometers, thus too large of an increment step.
                4.  30, 1998 to 35, 1998- Loose wire from datalogger to multiplexer.
