MATRIP: Mongolian-American Tree-RIng Project

MATRIP [pronounced /may-trip/] - a research collaboration between Mongolian and American scientists.

Mongolian Research Overview:

Mongolia possesses one of the most extreme continental climates in the world. Very little long-term climatic information is available for Mongolia. The dendroclimatic studies will determine:
1) if there is any evidence about climatic change in this relatively unknown, yet very important region

2) how it relates to larger-scale global changes.

We have initiated studies of Mongolian paleoclimate that includes temperature, precipitation and streamflow reconstructions. A map of Mongolia will give perspective on Mongolia's location within the Asiatic continent. [For a slightly better quality map, patience is required - >900K!]

Current Studies:

1) Central Mongolia surface temperatures for the past 1700 years.

This study shows unusual warming this century versus the previous 1000 years. It was published in Geophysical Research Letters in 2001 {see Publications below}.

2) An adaptation of a paper reporting the preliminary investigations of temperature and precipitation for central Mongolia is now available online.

3) Annual precipitation reconstruction from 1651 - 1996 for east-central Mongolia.

This study is currently in press. A picture of a typical tree at the site can be seen here!

4) Annual streamflow for the Kherlen River in eastern Mongolia.

This reconstruction (KRS) is currently in press. It was constructed using trees from the Urgun Nars and Zuun Mod [100 Trees] site.

Continuing Studies:

We have recently made collections from western Mongolia. An exciting discovery is the sampling of a Siberian larch over 700 years old. This tree was alive when Mongolia ruled much of the Asian continent under Khublai Khaan!

We will continue to build a network of tree-ring sites to further explore climate characteristics within the region of Mongolia.

Other Products:

28 sites have been sampled to date. One in particular, Sologotyin Davaa (SolDav; formerly called Tarvagatay Mts.), has been used by ourselves and others in reconstructions and analyses of large-scale to hemispheric temperature variations over the past four centuries.
