Update Notes

• 03-Sep-2004: Upgraded all software to Fortran95. Initialisation functions removed.
• 19-Nov-2003: First release.

• The code requires a Fortran95 compiler.
• Each program tarball contains all the required code, test datafiles, and a makefile for unix platforms. The makefile names in each program tarball are the same, so if you explode the tarballs in the same directory, rename them to prevent overwriting.
• All the required support code/modules are replicated in each tarball.
• All compilation macros and rules are defined in make.macros and make.rules respectively. The make.macros file contains the default compiler options for all the tested systems:
  • linux using Intel (v8.1.023)
  • linux using Lahey (v6.2c)
  • linux using pgf90 (v5.2-4) [1]
  • linux using g95 (Dec 20, 2004) [2]
  • SGI IRIX64 [3]
  • Sun Solaris
  • IBM AIX
  Simply typing make on the command line will select the correct platform. For linux systems, you should check the Linux_FLAGS macro definition in the make.macros file to determine the default compiler.
• The netCDF I/O code requires the netCDF libraries and the Fortran90 API. You can get more information from my netCDF page, or you can visit the Unidata netCDF page to download and install the netCDF libraries.
• If you are compiling on a SunOS system, you must change the makefile include macro
     INCLUDES = -I$(HOME)/local/netcdf/include
  to
     INCLUDES = -M$(HOME)/local/netcdf/include
  The Sun compiler uses a different switch (-M) for including module interface files (the .mod ones).

1. If you are using the PGI compiler, you must have at least v5.2-1, their Fortran95 compiler. However, this version of the compiler is buggy and will most likely not compile all the source code. Fixes for the most egregious problems were scheduled for the v5.2-2 release but I'm still having problems with the 5.2-4 release. Regardless, I've given up on this compiler for now.
2. The netCDF libraries compiled successfully with this g95 release. However some of my application test programs failed using the g95-compiled netCDF libraries where the Intel and Lahey generated libraries worked fine.
3. If you are on an SGI, you may or may not be able to compile all the code. As far as I can tell SGI don't have their own f95 compiler -- but you can purchase SGI ports of the NAG f95 compiler. The SGI MIPSPro f90 compiler can handle most Fortran95 syntax, but not all. In particular, my SGI test platform had problems with name specifications on END INTERFACE statements but, strangely enough, only for defined operators not generic procedures. More seriously, it appears that the SGI MIPSPro f90 compiler accepts the use of the NULL intrinsic in derived type pointer component initializations, but may not actually nullify the pointer. A compiler switch may force this behaviour, but I haven't tested it.

• Program to test the netCDF I/O functions: SRF_netCDF_IO_Test_software.tar.Z
• Program to test the ASCII I/O functions: SRF_ASCII_IO_Test_software.tar.Z
• Program to convert ASCII format SRF files to netCDF format: SRF_ASCII2NC_software.tar.Z.
  This tarball does not contain any input ASCII SRF files. I'm distributing this code for people who want to convert their own particular instrument SRFs to the netCDF format I described. You can create your own ASCII SRF files easily by looking at the ASCII format description.
• Program to average multiple detector SRF files: Average_SRFs_software.tar.Z.
  This code reads the netCDF SRF data of different detectors for the same sensor channel and produces a "channel average" SRF.
