We are about to launch 3000 workunits of our new ‘hadam4h’ application running on linux. This will have a global resolution of ~60km and a higher vertical resolution than before as well which should enable us to do some new and interesting science. We wanted to make volunteers aware that currently this model has a longer time between checkpoints and they will be larger than the N144 checkpoints. We have tested the application and believe the model should run smoothly but wanted to give advance notice that if there are any large scale issues associated with this batch it may be necessary for us to abort these simulations from client machines. Please do let us know via forum posts if there are any major problems. We look forward to sharing the results with you in due course.

I am currently working on batches 861 and 863 on four Linux machines. These batches are stated to be "HadAM4 N216 for winters starting in 2091-2100".
Without giving away any scientific results, can you illuminate me on why so far out?

Is anyone really interested in that, or is it more for forming a baseline of some sort for other projections?

Thanks.

I don't know any more about these tasks but given that many children alive today will be alive to tell whether the results predicted were accurate or weather a 2K rise in temperature was wildly optimistic or for that matter pessimistic, it doesn't seem that far out to me however your query has been passed up the line and someone there did attempt to answer but apparently did not have enough credit to post an answer. Another mod has asked Andy to allow him to do so.

Thanks for the follow-up.

While we wait for the researcher to get access, (or the working week), the following has shown up on an Aus news site:

Darwin River Dam at lowest level since 2006, but NT Government quiet on action

The relevant part:

Mr Durling said Power and Water was planning its future using long-term "climate change information provided by the Bureau of Meteorology and CSIRO".

"We look at horizons including 2030, 2065 and 2090 to incorporate those planned changes," he said.

I assume that this Darwin River and it’s dam are in Australia.

Yes, it's in the Northern Territory, which is the bit at the top in the middle.
To the left is Western Australia, and to the right, Queensland.

Hi Jim1348 - sorry it's taken a while for me to get sorted out with an account that gives me permission to post and reply to you. To build on what the others already said, people who use climate simulation data are interested in a range of time scales, from the next couple of decades out to a century away, or even beyond. Though, in this case the 2091-2100 dates are not meant to literally refer to those years - the simulations are for scenarios where the climate system has equilibrated at 1.5C or 2C warming above pre-industrial, corresponding to what would happen if the Paris Agreement goals were met, and so they could correspond to a much wider range of future years - we call the range of years 2091-2100 for convenience. It's a range of years because each year has sea surface temperatures and sea ice differing from the average in the same way as has been observed before (over 2006-2015), so the simulations include a realistic amount of year-to-year variability. I hope that helps.

Peter,
Yes, thank you very much. I thought it might be representative of something, I just could not figure out what the something was.
We will crunch away.
