Climate@Home is a research project that uses Internet-connected computers to do research for climate change prediction. You can participate by downloading and running a free program on your computer.
The initiative, called Climate@Home, is unprecedented in scope. Never before has NASA attempted to recruit so many people to help perform research vital to forecasting the Earth's climate in the 21st century under a wide range of different situations.

How to join Climate@Home Version 2?
Climate@Home uses BOINC, VirtualBox and Docker to support climate simulation. To join Climate@Home Version 2, you need to have:

    1) x86_64 machine
    2) Your BOINC client should be 7.6.33 and up
    3) You have to install VirtualBox
    4)If you are using Windows, your VirtualBox version should be 5.1.18; If you are using Linux or Mac, the VirtualBox version should be 5.0 and up



To join Climate@Home Version 2, please add this link:

What is the minimum requirement?
Each task needs one CPU core and 1024M memory. In addition, it needs 10 G Disk. To start the project, you will download a compressed vm_image.vdi, a docker image, related vboxwrapper and other small dependencies. The total size is about 1.1 G. However, the download only happens one time when you start to join the project.
For each task, you will upload results file. The project create results based on months count in task, i.e., the months count could be get form the work unit file (e.g., 6months_wu.xml). Each month takes about 30 to 4o minutes. So for a 6months task, it takes about 3-4 hours. The size of each month's result is about 8.1 to 8.2 M.

How long does it take to finish a task and how much credit can I get for per task?
It depends on the task you are running. If the work unit is a 6 months simulation (6months_wu.xml), it needs one CPU core and 1024M memory and the estimate time to finish it is 3-4 hours. Your will get 180 credit for your:

    1) computing contribution
    2) network contribution
    3) disk storage contribution



What is the speed to download the files and upload files
Don't worry about the network transfer speed. Climate@Home Version 2 has replicated files in following locations and it will select best endpoint to download and upload:

    climateinfovirginia.s3.amazonaws.com
    climateinfoohio.s3.us-east-2.amazonaws.com
    climateinfocalifornia.s3-us-west-1.amazonaws.com
