ABSTRACTS UDK 551.543.3 551.511.3 Shumilov O.I., Vasiliev A.N., Kasatkina E.A., Voronin A.I., Noskov S.P., Struev A.G., Kulichkov S.N., Raspopov O.M. A high latitude complex for measurement of atmospheric waves and electricity // Instruments and methods of geophysical experiment. - Apatity: KSC, 2003. - P.6-18. The description of high-latitude computer-aided complex for measurement of atmospheric waves and electricity is given. The complex had been installed in PGI (Apatity) in August 2000 and consists of 3 spatially placed (base ~300 m ) microbarographs for measurements of atmospheric pressure variations within the period range of Is - 40 min, a net device for air conductivity measurements "Electroprovodnost-2" and a device for measurement o f vertical component of atmospheric electric field "Pole-2". The computer-aided system permits to get information in the frequency band 1 - lO"4 Hz. The short review on the role o f information obtained by the complex in the light of ionosphere-troposphere interaction problem is given. The first results concerning features of infrasound and internal gravity waves are considered. Fig. - 6, ref. - 29 titles. UDK 550.385.681.3 Vassiliev A.N., Voronin A.I., Noskov S.P., Freger E.M. The network structure for collecting geophysical information for the Lovozero observatory // Instruments and methods o f geophysical experiment. - Apatity: KSC, 2003. - P. 18-28. The description of the modified equipment system for collecting geophysical information is provided. As oppose to the previously constructed one at the Lovozero observatory, this complex is additionally equipped with a digital magnetometer with 5 nTl resolution, based on magnetic statistic sensors with the photoelectric transformation, designed and constructed at the PGI. A description is provided of the PGI constructed 20-bit analog-digital transducer and the communication controller as well as PGI designed and constructed new sensors o f induction magnetometer with square wave response. All the collection system is united in a network and it allows for prompt data transmission using a PGI installed modem. The system o f precision time reference and synchronizing o f the entire system is achieved owing to GPS. A brief description is provided for the software used, which makes the autonomous functioning of the system possible. Fig. - 4, tabl. - 1, ref. - 4 titles. 186
