Hi I´m teaching in a science-class (students age 16) in Sweden. The classes will be for one semester (5 months). The question about global warming could be well illustrated by setting up a climateprediction project. The student have their own laptops and my idea is to have them run climateprediction. The class could work togehter as a team and would compete against other classes (I´m doing this in two classes). We also could arrange a competition against other school i Sweden or Europe. But - because of short time (5 months) the model would probably not be run completly. If we start up about 60 clients, but none is completed (maybe 50%) - will this anyhow contribute to any useful information for the main project? Or do you have any other suggestions how to use climateprdicition as a student project? Thanks for any comments. /Nils Orebro, Sweden |

In the climateprediction.net preferences on the account page of each user, there is, near the top, the option to pick between (currently), 2 types of models. The HADSM3 model is a lot shorter. However this model type has a limited life, and won\'t be available for long, so don\'t leave it too long if you want to start a whole bunch of them. If you know that you have no way of completing even these models, then the longer models (HADCM3), work differently, by returning data near the end of each model year. (4th December) So each model year completed is data aquired by the project. The more data the better, but even the data for partially completed models is usefull. At present, 50% of these 160 models would take them to the end of the Hindcast phase, at the year 2000. On the other hand, Any Day Now, (also, Real Soon Now), there will be shorter 80 year models, which will start in year 2000. If it takes you a few days to set things up, these 80 year Forecast models may then be available. Which ever way you decide to go with this, good luck. And don\'t forget to keep the laptops raised above the desk a little while running these models to get plenty of cooling. Otherwise you\'re risking a cracked desktop, as has happened to a couple of other people. Backups: Here |

The HadSM models are still a lot shorter than the 80-year coupled models (less than half as long), and you can\'t choose whether the server should send you a 160 or 80 year coupled model. You could be sent either. Les, if by the time Nils is setting this up there aren\'t many HadSM slab models left on the main cpdn server, are the ones still available on the beta project the same? As far as I know the beta and cpdn main site slab models are the same version. http://climateapps1.oucs.ox.ac.uk/beta/server_status.php Nils, there are a few cpdn slideshow presentations about the project and distributed computing in general. I\'m sure we could find them for you if you think your students could handle the English. You\'d be talking and explaining it in Swedish anyway. Let us know if you\'re interested. Cpdn news |

There are also the SAP models (HadAM3) from http://attribution.cpdn.org which take about 2 weeks to run (and have more detailed graphics because it\'s a high resolution model). However I wouldn\'t recommend running them on a machine with less than 1GB of RAM (SAP uses up to 450MB, whereas Slab only uses 48MB of RAM). I'm a volunteer and my views are my own.

Thanks for info. Started up a SAP-model from CPDN today. It reports to run about 530 h. First i would´nt start (reported lack of hard disk memory), but after some time it started ok. I tried to find the team I defined on climatepredicteion.net, but could´nt find it. Had to define a new team on CPDN. I like the idea with teams since I can define teams with my two classes competing to each other. Probably I will start up with my students next week with the SAP-model since we have 2G of internal memory. /Nils |

Nils, I\'m reposting this for you because you included your full email address. Google and the other search engines pass through the forums regularly. Spammers want email addresses. Nils said \'...there are a few cpdn slideshow presentations about the project and distributed computing in general.

Yes - thanks - that would be useful. E-mail to nils-borje dot eklof at ore dot johnbauer dot nu /Nils\' I\'ll post here what I find. Better on the forum than in an email so we have a list of links for use by other people too. You\'ll need to look again from time to time because I\'ll add more as I find it. Cpdn news |

This is the BBC presentation of the Climate Change experiment results. The models used were the same as the current cpdn HADCM 160-year models, 1920-2080. http://www.bbc.co.uk/sn/climateexperiment/ If you want some photos of climate change with a big visual impact, for example pairs of photos of the same glacier 100 years ago and now, Gary Brasch\'s website is good. http://www.worldviewofglobalwarming.org/index.html If the students\' English is good enough, the BBC Climate Challenge game is good. The students could do it with an English, Geography or Economics teacher. http://www.bbc.co.uk/sn/hottopics/climatechange/climate_challenge/ Cpdn news |
