simple question

Dear all,

just a silly simple question.... beeing still a newbie working with netcdf..
I create a nc file with dimensions x = 162 and y =  76
with a daily timestep for 10 years, 4 variables ( 1 real, 3 integer)
How large should such a file be....
because just by creating it grows up to 568 MB.
Is such size reasonable ? seems to be to large to me..

Second question
it is possible to open an netcdf file and write from several processes to it..
I know already that several processes can have read access to one file, with one process writing...

greetings

hannes
