weird ncdf4 output 9.969210e+36
Hi, This is the number for missing value in most of NetCDF files. http://www.unidata.ucar.edu/software/netcdf/docs/BestPractices.html#Missing%20Data%20Values This means you missed to provide/utilize the missing value attribute when you read your file. Regards, Pascal

Hi All:
I am trying to create a 3 dimensional (200*200*8760) netCdf file using the
ncdf4 package. Everything goes fine, except some unexpected outputs. Here is
tail of the result in one grid cell. I cbind the original values and the
output read from the nc file.
Original ncdf4
[8755,] 70.47247 7.047247e+01
[8756,] 47.10336 4.710336e+01
[8757,] 38.70509 3.870509e+01
[8758,] 32.86281 3.286281e+01
[8759,] 21.90854 9.969210e+36
[8760,] 10.95427 9.969210e+36
Most ncdf4 data matches with the original data, except the last two values.
There are extremely large values: 9.969210e+36
I have no idea where these huge values come from, and can't figure out where
is wrong at all.
Any one met the same problem before? Thanks for any suggestion, and I really
appreciate any help.
Thanks
Jianhua
