Lõuna-, Kesk- ja Kirde-Eesti aluspõhjakivimite stratotüüpsete paljandite seisundi hindamine
No full textKäesolev projekt on Eesti Stratigraafia Komisjoni algatatud jätkuprojekti neljas etapp, mis viidi läbi Lõuna-, Kesk- ja Kirde-Eestis ning tegeles stratotüüpsete läbilõigete seisundi kirjeldamise ja nende püsivuse hindamisega. Projekti raames täpsustati stratotüüpsete paljandite asukohti ja hinnati nende seisukorda, et soovitada meetmeid nende geoloogiliselt tähtsate läbilõigete säilimise tagamiseks. Seisundi hindamisel ja soovituste andmisel on arvesse võetud Rahvusvahelise Stratigraafia Juhise põhimõtetest tulenevaid nõudeid. Läbilõiked kategoriseeriti, sest nende käsitlemine samatüübiliste läbilõigete gruppidena andis parema ülevaate esinevatest tüüpilistest probleemidest. Soovitused kaitserežiimi kohaldamiseks või muutmiseks esitatakse lähtudes optimaalsetest tingimustest, mis tagaksid objektide säilimise pikemas perspektiivis. Aruandes tuuakse välja ilmnenud probleemid, mis vajavad lahendamist, ja erinevate kaitserežiimide rakendamise võimalused. Lisaks on käesoleva projekti aruandes mõned stratotüüpsed läbilõiked teistest Eesti piirkondadest, mis erinevatel põhjustel jäid eelmiste projektide kokkuvõtetest välja
Dataset of air ion and aerosol measurements. Tahkuse 2004-2014
No full textThe present dataset of air ion mobility and aerosol particle size distributions is a follow-up of the dataset Tahkuse_1993_1994, http://datadoi.ut.ee/handle/33/22. It makes available results of routine measurements in Tahkuse Air Monitoring Station from 01.01.2004 to 31.12.2014. The station is located in the Sepa farmhouse in Tahkuse village about 27 km northeast of the city of Pärnu, Estonia. Geographical coordinates are 58º31'28"N, 24º55'32"E, 24 m a.s.l. The farmhouse is surrounded with flat open landscape with some tree groups, grassland and agricultural land. The level of air pollution is typical for atmospheric air at a sparsely populated rural area. The dataset includes results of simultaneous measurements of positive and negative air ions and neutral aerosol particles. The small air ions are charged molecules and clusters up to 1.6 nm, the intermediate and large air ions are charged fine aerosol particles of size 1.6 – 70 nm. The air ion spectrometers are the same as used in Tahkuse during 1993 – 1994. Important upgrades of the instrumentation are taking into use the aerosol particle size spectrometer EAS and the AlphaGUARD radon monitor. The spectrometers are installed in the attic of the building. The air intake is at a height of 5 m above the ground. The continued measurements of wind speed, wind direction, air temperature, relative humidity, and concentration of NO2 are complemented with measurements of air pressure, sun radiation and radon activity concentration. The detailed description of the landscape, station, and instruments is presented in the thesis by Hõrrak, U. (2001) Air ion mobility spectrum at a rural area, https://dspace.ut.ee/handle/10062/50218. The measurements are saved into 11 yearly files as a tab-separated ANSI text. The zip-package of files should be downloaded from the present website, unpacked and operated in the personal computer of the scientist. The data can be immediately opened and analyzed using MS Excel as well as by means of different computer programs, which are able to process the ANSI text. Every file consists of a table with 114 columns and 8761 or 8785 rows. The columns correspond to variables and rows to measurement hours. The data are written without omissions for 24 hours per day even when the measurements were stopped or failed and the values of variables are unknown. The missing values are marked with the code –99. The data is accompanied with an instruction for the user Tahkuse_data_2004–2014_guide.pdf and a presentation of data preparation algorithms Tahkuse_data_2004–2014_supplement.pdf. The authors acknowledge Aadu Mirme for great work designing the original instrumentation

political engagement of young people
FinEstIon2003_06. Dataset of air ion and atmospheric nanoparticle measurements
No full textThe dataset provides measurements of the mobility and size distributions of charged molecular clusters and fine aerosol particles naturally found in atmospheric air. The genesis and subsequent evolution of nanoparticles is a key to understanding the formation of atmospheric aerosols, which is an essential factor of the Earth's climate. The particles are classified according to their size and electric mobility. The particle electric mobility was immediately determined while the size was calculated as the mobility equivalent diameter of the nanoparticle. In atmospheric electricity, the charged molecules and clusters up to 1.6 nm in diameter are called small air ions, the charged aerosol particles of size 1.6–7.4 nm are called intermediate air ions, and the charged aerosol particles of size 7.4–70 nm are called large air ions. The dataset includes results of simultaneous measurements of positive and negative air ions in three stations during four years from 2003 until 2006. The small and intermediate air ions were measured at Hyytiälä, Finland (61°51'N, 24°17'E, 180 m a.s.l.), Tartu, Estonia (58.373 N, 26.727 E, 70 m a.s.l.), and Tahkuse, Estonia (58°315'N, 24°555'E, 27 m a.s.l.), while large air ions were measured only at Tahkuse. The air ion measurements are accompanied with basic meteorological data. The dataset is not designed for direct running via the Internet. Complete package of data, software, explanations, and instructions Finestion2003_06.zip should be downloaded from the website, unpacked, and operated in the personal computer of the scientist.
Full set of measurements is saved as a single file, which can be opened using MS Excel. However, the whole data table is large and analysis of data immediately by means of Excel appears to be inconvenient. Thus the dataset includes a dedicated application, which allows easily extract specific subtables, and presents some extra facilities for manipulation with the time and selecting the variables in modified order. Instructions and descriptions are presented in the document Finestion_guide.pdf, which includes references to additional documents and data files.
The authors acknowledge Hilja Iher and Kaupo Komsaare for taking care of the instruments, Markku Kulmala for organizing measurements in Hyytiälä, and Sander Mirme for presenting additional meteorological data
ATMEL2007
No full textThe joint dataset ATMEL2007A (Tammet, 2009) provides scientists with a tool for studying the correlations and trends in fair-weather atmospheric electricity, air pollution effects, and trends in global climate on a broader basis. It includes hourly averages of digitally available data from 12 stations including 7 stations of the former World Data Centre network. Additional stations are Wank Peak (Germany), Marsta (Sweden), Tahkuse (Estonia), Tartu (Estonia), and Hyytiälä (Finland). The atmospheric electric measurements are accompanied with meteorological and air pollution data. The total amount of included hourly average values is about 12,000,000. New data can easily be imported into the dataset and the excerpts of the data can be exported as traditional tables using the included free software.
Fresh data is the property of scientists who have carried out the measurements. As a rule, the data are not made public until it has been analyzed and the first scientific papers have been published. The dataset ATMEL2007A contains only the data which have been decided to make public by the copyright owners. The most important source of the initially public data is the collection of files of the WDC/AE at the MGO. The collection was compiled due to the efforts of Dr. Ya.M. Shvarts and delivered to the University of Tartu, together with the data publishing rights.
An essential complement to the WDC data is the Wank Peak data collection by Reinhold Reiter, which contains 9½ years of continuous measurements. The Wank Peak data were reconditioned at the Max Planck Institute for Aeronomy, Katlenburg-Lindau, Germany, and published on CD-ROM by Prof. K. Schlegel. Some additional information required for the data interpretation was kindly presented by Dr. W. Carnuth as a personal communication. A 4½ year subset of atmospheric electric measurements at the Marsta Observatory of the University of Uppsala is for the first time published in ATMEL2007A. This data was digitally
recorded during 1994-1998 (Israelsson and Tammet, 2001). The Wank Peak and Marsta datasets additionally include the measurements of background meteorological parameters.
Today, the air ion mobility distribution is routinely measured at Tahkuse, Estonia (Hõrrak et al., 2003), at Tartu, Estonia, and at Hyytiälä, Finland (Kulmala and Tammet, 2007). The data are available since 2003 for Tahkuse and Hyytiälä, and since 2004 for Tartu. Hourly averages of air conductivity and ion concentrations are made public in ATMEL2007A for the first time. However, the dataset includes only the integral parameters of air ions: air conductivity, concentrations of wide ion groups, and average mobility of cluster ions. The original 10-minute records of detailed mobility distributions at Tartu, Tahkuse and Hyytiälä were still not opened for public access when compiling ATMEL2007A. A small but important part of ATMEL2007A is the classic data of electric field measurements made during the Carnegie cruises 4–7 (Mauchly, 1926). The digitized data were presented for ATMEL2007A by Dr. E.R. Williams (Williams, 2007)
OneSecondAirIons_2011_1. Dataset of corona-generated air ion measurements
No full textThe dataset contains two tables, one for positive ions and another for negative air small ions. The tables are presented in the form of text files, where the values within two different sequential columns are separated by one tabulator. Such text files can be imported into several software programs, including MS Excel.The dataset provides a sample of the results obtained by measurements of the mobility distributions of one-second-aged corona-generated ions formed in the ambient atmospheric air. It presents the detailed mobility distribution of these ions between 0.6 and 2.8 cm2V–1s–1. The mobility equivalent diameters are between about 0.42 and 1.5 nm. The genesis and subsequent evolution of air ions is a key to understanding the formation of atmospheric aerosols, which is an essential factor of the Earth's climate. In particular, the chemical composition of small air ions is known to be sensitive to the concentrations of several air trace gases. Our data are substantially different from the ones obtained by a relatively widespread technique that is also called “ion mobility spectrometry” but commonly measures the ions that are only few milliseconds old. The data also differ from the ones, obtained by widespread routine measurements of natural ion composition. Our unique measurement device can deliver the results that allow to derive certain scientific results, not attainable from other data.
The dataset includes results of simultaneous measurements of the positive and negative ions generated in the ambient outdoor air during three months of year 2011. The devices were located in a building within a small town. The air ion measurements are accompanied with basic meteorological data. The dataset is not designed for direct running via the Internet. Complete package that contains data and explanations should be downloaded from the website and operated in the personal computer of the scientist. The data are saved as tab-delimited text files, which also can be opened using MS Excel. The author acknowledges Kaupo Komsaare for help within the measurements, Jaan Maasepp for technical help, prof. Hannes Tammet for valuable comments and Urmas Hõrrak for supervision of the measurements
