Download Model Generated DataFiles

Model generated data is organized according to time frequency (indicated by subdirectory), climate variable (indicated by file name), and simulation number (indicated by file extent). Model DataFiles contain several records of increasing time. Each record contains a title and 72 x 46 data values that span the entire Earth according to the Model's grid. Each Model simulation was integrated for 150 years, from 1950 to 2099.

Below this paragraph choose the time frequency of the data you want. We suggest creating subdirectories like M1 , A1 , M10 or A10 for each time frequency, and, in the subsequent pages where you are given the chance to download Model DataFiles one at a time, redirect the transferred files in the "Save As ..." box to the proper subdirectory.

Click on the time frequency of the Model DataFiles you want. Note the size of each file transferred.

M1 DataFiles for each individual month.
Each file is 24 Mbytes and contains 12*150 = 1800 records.
A1 DataFiles for each individual year.
Each file is 2 Mbytes and contains 150 records.
M10 DataFiles for decade monthly averages.
Each file is 2.4 Mbytes and contains 12*15 = 180 records.
A10 DataFiles for decade annual averages.
Each file is 0.2 Mbytes and contains 15 records.

If you intend to download several DataFiles, it will be more efficient to use our anonymous ftp site where the DataFiles actually reside.
From a UNIX prompt, enter: ftp aom.giss.nasa.gov
For Name enter: anonymous
For Password enter your E-mail address or anything.
Useful commands when using anonymous ftp sites are: binary , dir , cd , pwd , get , mget , quit .
You should execute binary before getting any DataFiles.
Make sure that the size of the DataFile you obtained is identical to that on the ftp site.

You may want to download QDF.FOR which is a Fortran program that lists the record titles of a DataFile.

Some quantites may not have been stored but can be derived from available quantities.
Relative humidity can be derived from temperature and specific humidity.
Ocean steric expansion can be derived from ocean surface height and ocean and sea ice mass.
