Department 3 "Monitoring Systems and Data Management"

Network of Monitoring Stations built with CAIAG participation

At the current time the network of monitoring stations in installation of which CAIAG participated consists of 23 permanent stations which operate in Kyrgyzstan, Tajikistan and Uzbekistan.

 One of the stations is GNSS station BIS2. It places on CAIAG building and is connected to Internet with Institute LAN.

Other six stations are installed in compliance with Research and Development Programme of the Institute.  Location of two of them is Eastern part of Issyk Kul valley.  Previously received data shows that the quit intensive deformations of Earth surface reaching 4-5 mm/year  occur in this area. For intracontinental region with a distance ~ 40 km it is sufficiently large. So the GNSS stations Kerege-Tash (KRGT) on northern slope of the range Terskey-Alatoo  and  Kara-Batkak (KRBK) in southern foothills of the range Kungey-Alatoo.                        

Other two stations Arslanbob (ARSL) и Tash-Kumyr (TKUM) are located to southwest from Fergana range near Togtogul hydro power station. The data of preliminary study showed significant deformations here too.

Two more stations installed by the Research and Development Programme are the smart-stations. They are   Inylchek (ENEL) and Aksai (ASAI) and include GNSS receiver, meteorological and seismic equipment. Station танция Inylchek is located at eastern part of Kurgyzstan near with same name the river and glacier Енылчек, which is the biggest in Tien Shan. The station Aksai is at eastern end of Aksai valley - the highest in Kyrgyzstan. In 2012 it is requipted with the project GCO-CA help.

Other project that develops the network is "Central Asia Water" (CAWa). Hydrometeorological ROMPS stations  of this project have in their structure the hydrological and meteorological sensors, GNSS receivers. Total quantity such the stations in Kyrgyzstan are four. They are Baytik (HM01) located at foothills of the Kyrgyz range to the south from Bishkek,  Taragai (TARA) - in 70 km to south from Issyk Kul lake, Kokomeren (KEKI) is at Kokomeren river in village Aral, Abramov (ABRA) is at Abramov glacier near the state border with Tajikistan. In 2012 year two same stations were also installed in Tajikistan. They are the station Dupuli (DUPU), located at Zerafshan river in 20 km to the east from city Penjikent and station Ayvaj (AYVA), which is installled in the village with same name near Kafirnigan river at Afghanistan border. Seventh station Maidanak (MADK) of this project is placed in Uzbekistan at 40 km to south of Shakhrisabz city of Kaska-Dariya province.

The suite of connected stations is built thanks to project GCO-CA. These are two stations Merzbacher (MRZ1 и MRZ2) disposed near Merzbacher lake at north and south sides of the glaciers Northern and Soutern Inylcheks. Third station станция ICED is installed on the ice dam of the glacier and serves for measurement of glacier motion velocity and observation of the dam. 

Station Sufi-Kurgan (SUFI) is a seismic station which GFZ handed over to CAIAG and it is a part of the seismological network Caremon/ The station is located to southeast from Osh city.

The transition zone between Pamir and Tien Shan is one of the most tectonically active area in Central Asia. In October 2013 the Pamir-Alai GNSS profile was installed across the western part of the Alai valley to better understand these tectonic processes. The GNSS profile consist of 4 permanent stations (ALAI, ALA1, ALA2 and ALA3). The main station (ALAI) provides a VSAT link for data transfer. The slave stations stream the data directly to the main station by the HF links.  A location scheme of the GNSS stations and directions of data transfer (blue lines) by radio links are shown on the figure below. GNSS profile concept was developed by scientists of CAIAG (Department 3) and GFZ (Section 1.2).
