Memory Blowup Issues

I am dealing with some good sized data sets from satellite data. These 
data are stored in hdf format. The problem is that I process a sequence 
of these data sets by Importing and then processing; however, it seems 
that the memory usage grows with each Import, even if I Remove the data.

Here is a somewhat simplified example:

MemoryInUse[] (* some data already read in *)

Data=Import[fileName,"Data"]; (* import a new data set *)

Data=Import[fileName,"Data"];(* import  it again *)

Remove[Data] (* this has no effect on the memory usage *)

As you can see, I will shortly run out of memory. Any ideas?
