Climateprediction.net download
| Welcome to the climateprediction.net
model download pages.
How to participate in the experiment
- First, download the package using the link at the bottom of this
page. The size of the download is about 8 Mbytes.
[This package has been digitally signed so you can verify that it has
been produced by the climateprediction.net team. For maximum
security, we recommend that you set the security level in your browser
to a sufficiently high level to check the digital signature. If you
do this before downloading, your browser should pop-up a dialogue box
indicating that the file was produced by climateprediction.net.
N.B. Not all browsers have this facility. Older ones might not, and
even more recent browsers will only provide this information if you
download AND "Open", but not download and "Save"!]
- The package you download is a self installing file.
Simply double click on the downloaded file in Windows Explorer, or let
your browser run it automatically when the download is complete. At
this point you will need to have suitable privileges to install new
software on your machine. For Win NT, 2000 and XP that means that you
must have an Administrator account.
- The installation process will now begin; simply follow the instructions
in the various windows.
- During the install procedure, you can choose between installing the
model as a process or as a service.
If you choose to install it as a service (recommended), it will automatically
start running whenever you switch your computer on, regardless of whether
you or another user is logged in at your machine. In addition, running
climateprediction.net as a service means that it will run when
the machine is on but no-one is logged on. If you install it as a process,
it will only run when you manually start it up by clicking on the appropriate
icon.
- Once the installation process is complete it will automatically launch
the climateprediction.net software. This will gather information
about your machine, and ask you for some details such as your email
address etc. (we will NOT pass on your e mail address or details to
any other organisation). Just fill in the details, and click the "OK"
button. At this stage you need to be connected to the internet.
Register your details in our database of participants, and
download the files which will make your climate simulation unique.
[NB: You can register multiple machines, but you will need a password,
which will be sent to you when you register the first one.]
- Once registration is complete you may disconnect from the
Internet.
- The software will now have set the model going and a small icon will
have appeared at the bottom right of your screen. By double clicking
on this, you will launch the model interface which
lets you view how your experiment is progressing. You can view the surface
temperature and cloud fields in your model using the 'visualization'
menu on the model interface. Please be patient, it can often take 20-30
seconds for the visualization to start. The 'help' menu provides links
to web pages and the 'settings' menu allows you to view your registered
details.

- The model should not interfere with the normal use of your computer.
Nevertheless, you can pause it or stop it using the
"My Experiment" menu. You can also close the whole package down, and
restart it some time later using the shortcuts on your desktop and in
the Start menu. If you have chosen to run it as a service it will come
back automatically about five minutes later. If you are using Win NT,
2000 or XP (Home or Pro), your operating system allows multiple users.
You will have installed the package as an Administrator but you can
change to another user by logging out and logging in as the new user.
If you're running climateprediction.net as a process you can
then restart as the new user by accessing the link in the "Start" menu
- this will happen automatically if you allowed the installation procedure
to install shortcuts in your startup directories. If you are running
climateprediction.net as a service, the program will start automatically.
- Details of the
various stages of the experimental design of the project are available.
The current release is Experiment 1, a three-phase simulation using
a full atmospheric model but a simplified ocean. Between each phase
the output files from the model are processed. They are converted from
one format to another and critical features of interest to us are extracted
and stored in smaller files. This processing only takes about 5 minutes
at the end of each phase but during this period there is significant
disk access and consequently your machine may become sluggish.
If this is a problem, simply close down the whole package and restart
it at a more convenient time.
- Once all three phases are complete and all files have been suitably
processed (i.e. some weeks in the future), the client will try to connect
to our servers again. At this point it will prompt you to connect to
the internet if you are not already connected. It will then return a
series of files created by your simulation to our servers. The total
size of this upload is about 6MB. A window will pop up giving a large
amount of detail about how this upload is progressing. The files are
broken into small bits so if your connection is lost mid-transfer, it
can pick up from where it left off when you reconnect.
- When all the files we need have been returned successfully, the client
will download a new simulation for your computer to do and the
process will start again unless you choose not to continue.
We would like to encourage you to use the climateprediction.net Discussion Forum where
participants can share their views, and perhaps provide advice on some of
the common problems. Our team members regularly read the posted messages,
so most of your comments come to our attention within a few days.
[Note: In order to post messages on the forum, you will need
to register with the forum! This registration is NOT related to the
username and/or password you chose when you first installed your climate
model. You need to register specifically with the forum, the username/password
from your model is not automatically valid.]
