I am analyzing the recent climate change over Asia, and I am not familiar with Asian Russian region. Any publications on surface air temperature change over the past century in that region would be highly appreciated.
Viktor, do you know any one who is familiar with the observational methods and observational settings around the weather stations (or siting of the weather stations) in Siberia? Thanks.
You are welcome. Yes I know some people, some of them are my colleagues. Moreover my institute is responsible for developing methodology and verification of meteorological observations in Russia.
Viktor, Many thanks for your response. I know Prof Oleg Anisimov and Dr Vasily Kokorev. Do you know any others who are conducting the observational studies? If so would you please tell me their name and the contacts via email. My email address is: [email protected]. Regards.
We have found that urbanization has a significant effect on surface air temperature trends over the past decades in northern China, especially in wintertime. I wonder if it also contribute in some extents to the observed warming in winter in the vast Siberian region. I would very much appreciate if anyone explain the siting and nearby settings of the observational stations in the region, and any information about the observations done near or within cities and towns of Russia.
The "significant effect" you are describing sounds like the well known Urban Heat Island Effect. It only occurs in cities and urban communities so is unlikely to be present in the vast Siberian region. See

Hi, thank you very much Alastair for the information. I have read the paper by Grimm et al. (2008). The abstract in the EGU Geophysical Research Abstracts is really interesting, and I am looking forward to the final publications of the important research results.
Indeed, the Urban Heat Island effect only occurs in urban areas and the nearby belts, and it will be absent in the rural regions. Our concern is the urbanization effect on surface air temperature records which are generally observed near or even in the cities, and are used in monitoring of regional and global temperature change. In this case, the urbanization effect represents a bias in the historical climate data, and we have to make an acurate estimation and correction of the bias before we go for further studies.
Thanks Alastair. I want to learn the observational environment of the weather stations there. I have historical data for some stations, and I have no idea about the specific locations of the stations relative to the built-up areas of the cities and towns where they are located. Thanks a lot.
It might be worthwhile you contacting the Russian authors of the abstract I cited. Their instiutions have English web sites: http://www.eng.geogr.msu.ru/ http://www.ifaran.ru/index.html?&locale=en so you should have no problems communicating with them in English.
Thank you for raising this question, as by trying to solve it I have found a possible contact who could be very useful to me!
Very good, Alastair. I will go to check the link. You are welcome to contact with me via email ([email protected], or [email protected]). With best regards. Guoyu
Many thanks Timur. Do you know any one from Russia who will be interested in examining the urbanization effects on surface air temperature change as recorded at the current weather stations in Asian Russia?
