There are 3 files (other than this readme) on the CD.
1. SCENGEN.ZIP - This is the MAGICC/SCENGEN program.

2. FormatSCENGEN_forGIS.xls - This is an MS Excel workbook (2000) that converts output SCENGEN data into GIS importable format

3. ImportSCENGEN.aml - this is an Arc Macro Language (AML) script that imports the file output from the Excel macro into a GIS grid (ESRI GRID format)

To install MAGICC/SCENGEN:
1. Create the exact directory:
     c:\sg41
2. Unzip the SCENGEN.ZIP file into this directory.

To launch MAGICC/SCENGEN:
Execute: C:\sg41\SCEN-41\magicc\magicc.exe


To Run FormatSCENGEN_forGIS.xls:
1. Open the excel file and choose "Enable macros" when prompted.
2. Click on the  "Format SCENGEN" button
This will input the file: C:\sg41\SCEN-41\engine\imout\GHANDAER.OUT which is the output of greenhouse and aerosols file for the latest run of MAGICC/SCENGEN
It outputs to: C:\sg41\GHANDAER.txt
This file is in ASCIIGRID format and can be imported using ArcGIS or workstation. Alternatively, you can use the following script to convert to a GRID format and add projection information.

To Run ImportSCENGEN.aml:
1. Start ArcInfo Workstation (Arc: command prompt)
2. Type the following at the command prompt:
&r ImportSCENGEN.aml
Then follow the on-screen prompts.

By default, this outputs a grid to:
c:\sg41\grid\ghandaer
