SYSTEM REQUIREMENTS
The SOLAR2000 Research Grade empirical solar irradiance model is a binary IDL save file that runs with a Graphics User Interface (GUI). Any platform that has licensed Research Systems, Inc (RSI) Interactive Data Language (IDL) version 6.0 or higher can use this model. This includes:
Platform Vendor Hardware Operating System Supported Versions VMS Compaq Alpha VMS 7.1 UNIX Compaq Alpha Tru64 UNIX 4.0 HP PA-RISC HP-UX 10.20, 11 IBM RS/6000 AIX 4.3 Intel Intel x86 Linux 3.3* SGI Mips Irix 6.4, 6.5 SUN SPARC Solaris 2 2.6, 2.7 SUN Ultra Solaris 2 2.6 SUN Intel x86 Solaris 2 2.6 Windows Microsoft Intel x86 Windows 95, 98 Microsoft Intel x86 Windows NT 4.0 Microsoft Alpha Windows NT 4.0** Macintosh Apple PowerPC*** Mac OS 8.1, 9.2, OS X 10.1-10.4.2 * Red Hat 6.0
** IDL 5.3 is the last release that will support the Windows NT for Alpha platform.
*** Includes iMac and G3, G4, G5
IDL VIRTUAL MACHINE USERS:
Starting with SOLAR2000 Research Grade v2.23 and IDL 6.0 or higher, it is now possible to run the model on any platform without an IDL license. The IDL 6.0 VM is available via download from the RSI web site: http://www.rsinc.com/download/
Users must first download the IDL 6.0 or higher virtual machine (VM) and help on downloading and installing the VM can be found at the above web links. Once the VM has been downloaded and installed, a X-terminal window must be opened on the operating system to issue the following command:
idl -vm=solar2000_rg_vm.sav
DOWNLOAD INSTRUCTIONS FOR RESEARCH GRADE MODEL:
1. At http://SpaceWx.com, go to the "SOLAR2000" link, then "Downloads".
2. Register with your name, email address, and any comments.
3. Click "Download now" in your browser window. Your Browser will display an anonymous ftp directory, which will contain a number of files and subdirectories (there are two versions - one is "Observed" and pne is adjusted to 1 AU), e.g.,
- README
- s2krg_v*obs60.tar.Z (for UNIX, using uncompress and tar commands)
- s2krg_v*obs60.sitx (for Windows or Macintosh, using the "StuffIt Expander" decompression application which is widely available).
- s2krg_v*_obs_uncompressed (for VAX or other systems requiring binary downloads; no expansion of compressed files will be necessary).
4. Click on either of the two files to begin the download, saving it to a directory of your choosing. Unzip the file on your computer and, if you wish, place the new SOLAR2000 folder in the desired subdirectory or folder on your computer. See "Decompression Instructions" below.
Note: If your Browser fails to work as described above, simply use an FTP application or command to log ftp.SpaceWx.com (username: spcusr, password: usrspc) and use a binary "get" command. Depending on local firewall or encryption configurations (ftp can fail to respond), it may be necessary to toggle the ftp passive mode by typing "epsv4" immediately after logging in.
5. Decompression Instructions: After downloading the zip file (binary format) with either a .sitx extension for Windows or MacIntosh, or .tar for Unix systems, use these tips for decompressing the file into it's component files:
For Windows 98/NT or MacIntosh:
a. Move to any folder/directory as a default (e.g., solar2000rg_v2_23) which will contain all the files that will be necessary to run SOLAR2000. You may need to create this folder: it will serve as the default IDL working directory to run SOLAR2000.
b. Open a Zip application, e.g., Aladdin StuffIt Expander. If you don't have a Zip file application, they are widely available on the Internet.
c. Unzip the downloaded zip file. Depending on the application, this may be a two-step process. Note: Because of the wide variety of decompression applications, you will need to follow the instructions provided with the application.
d. All the necessary files should be should be created under an additional SOLAR2000 subdirectory. You may want to rename or move this subdirectory with all it's files to another location of your choosing. Be certain you have full read/write/execute privileges to all the files.
e. Read the s2k_readme text file, which contains the license agreement and IDL SOLAR2000 instructions for running the model.
For Unix:
a. Move to a directory above any directory as a default (e.g., solar2000rg_v2_23) that will contain all the files necessary to run SOLAR2000. You may need to create this folder: it will serve as the default IDL working directory to run SOLAR2000.
b. Type uncompress ./filename.tar
c. Type tar -xvf ./file_name.tar (e.g., solar2000rg_v2_23.tar)
d. Read the s2k_readme text file, which contains the license agreement and IDL SOLAR2000 instructions for running the model.
For VAX:
a. Move to a directory above any directory as a default (e.g., solar2000rg_v2_23) that will contain all the files necessary to run SOLAR2000. You may need to create this subdirectory: it will serve as the default IDL working directory to run SOLAR2000.
b. Download the files from the SpaceWx ftp server as binary files only. Some of these will be text files and some will be IDL save files. There is no need to unzip these files.
