Greetings! There are several ways to open netCDF files, but it really depends on how you wish to access the data contained within. What language or analysis package do you plan on using? We support the C, FORTRAN, C++, and Java languages, and have a visualization and analysis program called the Integrated Data Viewer that can read and view netCDF files (as well as a number of other weather and climate data formats), although there are several other languages and packages that will read/write netCDF through 3rd party support (e.g. Python, Matlab, Excel, IDL, etc.). Another question: where did you download the data? Depending on the type of dataserver, you may be able to get the data in a format that is more readily useable for you. Cheers!
