On this page we provide instructions for downloading and installing the Harvard-NASA Emissions Component (HEMCO) source code.

Overview

HEMCO requires the following libraries:

  1. A netCDF library installation:
    • HEMCO reads data files in the netCDF format, and as such, needs to have a version of the netCDF libraries installed on your system.
    • NetCdF-4 is preferred, but the older netCDF "classic" versions are OK too. Check with your sysadmin to see if your system already has the netCDF library installed.
    • If you need to install the netCDF libraries manually, then you will also need to have C and C++ compilers on your system. Most versions of Unix/Linux already come with the GNU C compilers gcc and g++. See the Install netCDF section below for more details.
  2. The NcdfUtilities package
    • This package contains Fortran utility routines for netCDF I/O.
    • It will be downloaded and installed as part of the HEMCO installation process.
  3. A Fortran compiler
    • HEMCO currently supports the following compilers:
      • Intel Fortran Compiler (ifort), preferred
      • Portland Group Compiler (pgf90).
  4. A version of the Perl scripting language
    • This is usually included with all builds of Unix/Linux.
