Quick Access to HDF and HDFEOS data with NCL NCL
(NCAR Command Language) is an interpreted
language designed specifically for scientific
data analysis and visualization. Excellent file
handling Easy access to h4, h5, he, and
he5. ncl_filedump can be used to check what is
in a file quickly. ncl_convert2nc converts HDF
and HDFEOS (and other) data to NetCDF file.
Handling HIRDLS data NCL can process and
visualize HIRDLS data. Below is a sample of O3
via OpenDap.
