BOINC Needs Votes at a UN Upcoming Forum
BOINC is a finalist for an notable award, and needs your vote (*by Sunday)
The World Summit on the Information Society (WSIS) (https://www.itu.int/net4/wsis/forum/2024) is a United Nations-sponsored initiative aimed at harnessing the potential of information and communication technologies to build inclusive and equitable information societies worldwide. BOINC has been nominated for a prize at the 2024 forum (https://www.itu.int/net4/wsis/stocktaking/Prizes/2024), and has passed initial hurdles; the next and last step ("Phase 3") requires public votes. The award would be a very nice boost and validation for BOINC and all our projects; if we can get our communities to vote, we should have a decent shot at this point...
Voting is pretty simple, takes just a few minutes; instructions are here: https://docs.google.com/document/d/1x9Xi3tq7Y9dlDD0Xb0Ul0yYCXct5pDqIqssqARxvrXg/edit.
(*The deadline for votes is Thursday April 04 (23:00 UTC+02:00))

New study going out to volunteer's machines
Indian Ocean experiment
This experiment aims to evaluate the importance of the Indian Ocean Dipole (IOD) event of the winter 2019/2020 on the strong and well predicted North Atlantic Oscillation (NAO) of the same winter. The NAO is of large importance to European winter weather as it governs the winds over the North Atlantic which are related to the mild and wet winters of northern Europe. It has been shown that the NAO is in some years influenced by anomalous tropical ocean conditions (like El Nino). We aim to show that the strong positive IOD of 2019/2020 had an influence on the NAO and resulting warm conditions of this winter. We use the large ensemble of the OpenIFS@Home to identify the connections between the tropical Indian Ocean and the North Atlantic region.

New study going out to volunteer's machines
STORMS: Investigating how low-pressure systems may change in the future
(actual project name - “Quantifying controls on the intensity, variability and impacts of extreme European STORMS”)
Victoria Sinclair, Clément Bouvier
Institute for Atmospheric and Earth System Research,
University of Helsinki, Finland
Throughout the year, low-pressure systems regularly move across Europe, usually from west to east, bringing cloud, rain and windy weather. Sometimes these weather systems can become very intense, and the winds and rain associated with them can cause damage to buildings and infrastructure, flooding, and can disrupt electricity supply and travel. Although the short-term weather forecasts of these storms are now quite accurate, it still remains uncertain how these storms, and their impacts, are likely to change in the future as our climate changes. Some of this uncertainty is because our understanding of what controls the strength and impacts of these storms is incomplete.
The aim of this project is to understand what controls the strength and structure of these low-pressure systems. We will quantify how the atmospheric state that the low-pressure systems develop in affects the strength and structure of these low-pressure systems. This atmospheric state can be described by various parameters, for example, the mean temperature, moisture content, and upper-level wind speeds (i.e. the strength and width of the jet stream). Since there are lots of different parameters we want to study (not just the ones described above), we want to do lots of experiments in a high controlled manner. Therefore, we will run a large ensemble of simulations of idealised low-pressure systems using the numerical weather prediction model OpenIFS. Although the simulations are idealised, the weather systems that develop look very like real weather systems that we observed in reality. Each ensemble member differs in its initial atmospheric state, and we choose these initial states to cover everything from the current climate to past pre-industrial climates to the most extreme future climate projections. This is exciting because although idealised simulations of low-pressure systems have been performed before, this is the first time that such an extensive exploration of the parameter space will be conducted.
Once we have the results from the large ensemble, we will calculate different measures of the strength of the storms and then use machine learning techniques to see how these relate to the initial states. Our results will hopefully increase in confidence in how these storms and their impacts will change in the future.

Request to volunteers to please enable: 'Leave non-GPU tasks in memory'
The OpenIFS model batches require the option 'Leave non-GPU in memory while suspended' to be enabled under boincmgr -> Disk&Memory. This will prevent the task from frequently restarting and reduce the risk of task failure.

Request for volunteers running pre-7.10 BOINC clients to update, due to an issue with pre-7.10 client versions not being able to connect with the project
Could we please ask climateprediction.net project volunteers to update their BOINC client software to the latest version. There is currently an issue with older client versions (pre-7.10) not being able to communicate with the climateprediction.net project. Updating your BOINC client software to the latest version will alleviate this issue.

Reminder for Unix/Linux Volunteers to ensure they have installed the 32-bit compatibility libraries
Just a reminder to all volunteers running climateprediction.net in Unix/Linux. Unix/Linux machines need to have the 32-bit compatibility libraries manually installed. If these libraries are not installed climateprediction.net workunits will crash when running. See the climateprediction.net forum for more information on this: https://www.cpdn.org/forum_thread.php?id=8008.

climateprediction.net project GDPR Compliance
The climateprediction.net project has now completed it's work on GDPR compliance. This has a number of effects:
- New users will only be able to create an account via the web site.
- Existing users will be asked to consent to the project terms and conditions next time they login to the web site.
- For all users there will be a new preference in the project preferences: 'Do you consent to exporting your data to BOINC statistics aggregation Web sites?'. By default this become 'No'. If you wish to continue to have your statistics exported to the BOINCstats site, you will need to logon to the website https://www.cpdn.org/login_form.php and go to https://www.cpdn.org/prefs_edit.php?subset=project and select the tick box.

Project news: Introducing the AFLAME project (Attributing Amazon Forest fires from Land-use Alteration and Meteorological Extremes)
The AFLAME project is funded through the Newton Fund Climate Science for Services Partnership Brazil via the Met Office and works collaboratively with scientists in the UK and Brazil.
There is an emerging realization that Amazonian wildfires that were formerly driven by deforestation and agricultural expansion, are now growing to unprecedented magnitudes because of meteorological extremes. These escaped agricultural fires are rapidly degrading remaining forests in the Legal Brazilian Amazon (LBA).
Within this project we aim to attribute the change in wildfire risk due to human induced climate change and predict how these wildfire occurrences may change in possible future climates. Other factors besides increased greenhouse gas emissions may affect wildfire incidence, for instance, large-scale natural variability in the climate system from events such as the El Nino Southern Oscillation (ENSO) as well as how the land is being used and deforested. We will be performing a series of sensitivity studies to determine the relative influence of each of these factors alone on Amazon wildfire outbreaks. To do this we will analyse the results from the distributed computing simulations for the occurrence of weather conducive to wildfire outbreaks and parse this output into a statistical wildfire module.
