Now that online meetings have been established and greatly reduce travel costs the homogenisation community has decided to try whether an online Homogenisation Colloquium works. We hope this can engage a wider community than in-person meetings.
The organising team are: Athanassios Argiriou, Chimani Barbara, Vanda Cabrinha Pires, Mary Curley, Beatrix Izsàk and Victor Venema. Please send us suggestions on interesting studies and topics for the next colloquium.
Announcements on future colloquiums will be send to the Homogenisation List.
Second online meeting
The second Homogenization Colloquium will be on Wednesday the 29th of June 2022 starting at 15.00 CET (2pm UTC).
We will have 1.5 hours with four talks (20 minutes each including Q&A) and a short break. Followed by half an hour of free discussions on homogenization where anyone can bring up a problem they are dealing with.
- Tamás Szentimrey on Possibilities for evaluation, validation of the homogenisation methods
- Peter Domonkos on Newer experiments with the U.S. daily temperature benchmark
- Lars Magnus Joelsson on Automation & evaluation of the interactive homogenisation tool Homer
- Moritz Buchmann Homogeneity assessment of Swiss snow depth series
If you are not on the homogenization list and did not get the call-in details, do mail me.
First online meeting
The first meeting on Wednesday, 12 May 2021, will have talks for the first 90 minutes (see program below) and discuss the format the last 30 minutes. (In later colloquiums the last part will be used for open discussions on any homogenization problems people may have.) You can join via Zoom. (No need to register.)
Something to discuss is whether we prefer the colloquiums to be more formal with talks about mostly finished work, have more educational talks, discus about one study or give an overview over multiple studies, or talk more informally about ongoing studies, seeking feedback. Recording the colloquium could help colleagues who are unable to attend (given their time zone), but would probably reduce the willingness of presenters to show unfinished work.
We should also discus topics. Some have suggested to not only do homogenisation, but also quality control and data rescue. Another option could be to simply make separate colloquiums for that. There is no need to bundle topics for virtual meetings like there is for physical meeting with much overhead. Organizers of colloquiums for related topics are welcome to use the same infrastructure (distribution list and video call systems).

How it all started
The 2020 pandemic Budapest Seminar was well visited, many were new people who might not have been able to go to an in-person meeting. So in the chat the idea emerged to experiment with an Online Homogenization Colloquium.
To get a first idea about the format we made a survey via the Homogenisation List. People clearly prefer a mix of talks and open discussions on any homogenization problems people may have.
There is also a clear preference for quarterly over monthly meetings. The colloquium will start at 3pm Central European Time. This way people in the Americas can join us in the morning and Asia in the evening.
The length of the colloquium was a toss up in the survey, it is about 50/50 for 90 minutes or two hours. So we will start with 90 minutes and when we notice we have too much material we can extend it later.
