Anyone encounter this before?

ncdump shows the following

        nv = 2 ;

        float lat(lat) ;
                string lat:long_name = "latitude" ;
                string lat:units = "degrees_north" ;

                string lat:axis = "Y" ;
                lat:valid_min = -90. ;
                lat:valid_max = 90. ;
        float lat_bnds(lat, nv) ;
