I got them, and  worked fine on both of them, so they seem to be
valid, uncorrupted netcdf files.  For example:

  $ ncdump -c sfcObs-monthly-3hrly-1971-1996mean.nc
  netcdf sfcObs-monthly-3hrly-1971-1996mean {
  dimensions:
          time = UNLIMITED ; // (108 currently)
          lat = 45 ;
          lon = 72 ;
  variables:
          float AH(time, lat, lon) ;
                  AH:long_name = "high cloud amount when IB=1 (%)" ;
                  AH:missing_value = -99999.f ;
  ...

   time = 100, 103, 106, 109, 112, 115, 118, 121, 124, 200, 203, 206, 209, 212, 
      215, 218, 221, 224, 300, 303, 306, 309, 312, 315, 318, 321, 324, 400, 
      403, 406, 409, 412, 415, 418, 421, 424, 500, 503, 506, 509, 512, 515, 
      518, 521, 524, 600, 603, 606, 609, 612, 615, 618, 621, 624, 700, 703, 
      706, 709, 712, 715, 718, 721, 724, 800, 803, 806, 809, 812, 815, 818, 
      821, 824, 900, 903, 906, 909, 912, 915, 918, 921, 924, 1000, 1003, 1006, 
      1009, 1012, 1015, 1018, 1021, 1024, 1100, 1103, 1106, 1109, 1112, 1115, 
      1118, 1121, 1124, 1200, 1203, 1206, 1209, 1212, 1215, 1218, 1221, 1224 ;
  }

So the fact that you get a runtime error running the same ncdump
command may mean there is something wrong with your netCDF
installation.  Does your ncdump work OK on other valid netCDF files,
for example the sample file:

 ftp://ftp.unidata.ucar.edu/pub/netcdf/sample_data/aR.nc
  
When I run ncdump -c on that, I get:

  $ ncdump -c aR.nc
  netcdf aR {
  dimensions:
          lat = 73 ;
          lon = 73 ;
          frtime = UNLIMITED ; // (11 currently)
          level = 5 ;
          timelen = 20 ;
  variables:
          float RH(frtime, level, lat, lon) ;
                  RH:long_name = "relative humidity" ;
                  RH:units = "percent" ;
                  RH:valid_range = -10.f, 110.f ;
                  RH:_FillValue = -9999.f ;
          float lat(lat) ;
                  lat:long_name = "latitude" ;
                  lat:units = "degrees_north" ;
          float lon(lon) ;
                  lon:long_name = "longitude" ;
                  lon:units = "degrees_east" ;
          int frtime(frtime) ;
                  frtime:long_name = "forecast time" ;
                  frtime:units = "hours" ;
          float level(level) ;
                  level:long_name = "level" ;
                  level:units = "millibars" ;
          char reftime(timelen) ;
                  reftime:long_name = "reference time" ;
                  reftime:units = "text_time" ;
          int grib_center(frtime, level) ;
                  grib_center:long_name = "center ID" ;
