Rahu, Jorma; Toll, Velle, 2021, "Anthropogenic aerosol impacts on clouds from SEVIRI satellite data", https://doi.org/10.23673/RE-283, DATADOI, V1
Anthropogenic aerosols offset an unknown fraction of greenhouse gas warming. We use geostationary satellite data to analyse continental polluted cloud tracks originating from isolated heavy industrial pollution sources in the European part of Russia. We study the temporal evolution of the cloud water response to aerosols. This item includes the dat... |

Hõrrak, Urmas; Iher, Hilja; Komsaare, Kaupo; Tamm, Eduard; Tammet, Hannes, 2017, "Dataset of air ion and aerosol measurements. Tahkuse 2004-2014", https://doi.org/10.15155/REPO-14, DATADOI, V1
The 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... |

Tammet, Hannes; Hõrrak, Urmas; Iher, Hilja; Salm, Jaan, 2017, "Dataset of air ion measurements Tahkuse_1993_1994", https://doi.org/10.15155/REPO-13, DATADOI, V1
The dataset makes available measurements of the mobility distributions of charged molecular clusters and fine aerosol particles in unpolluted atmospheric air at a rural area. 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 t... |

Palo, Timo; Jakobson, Erko; Jaagus, Jaak; Vihma, Timo; Sjöblom, Anna; Kilpeläinen, Tiina; Manninen, Miina; Maturilli, Marion; University of Tartu, Institute of Physics; Tartu Observatory; University of Tartu, Institute of Ecology and Earth Sciences, Department of Geography, 2017, "Vertical profiles of atmospheric variables based on tethersonde soundings from Ny-Ålesund", https://doi.org/10.15155/REPO-6, DATADOI, V1
Soundings were carried out on daily basis by using Vaisala tethersonde system DigiCORA TT12 with maximum altitude of 2000 m. The instrumentation consisted of 7 m3 helium filled balloon for lifting sondes, an electrical winch, three sondes suspended on the tether line below the balloon at approximately 20 m vertical intervals, and a ground station.... |

Luts, Aare; University of Tartu, Institute of Physics. Environmental Physics Laboratory, 2017, "OneSecondAirIons_2011_1. Dataset of corona-generated air ion measurements", https://doi.org/10.15155/REPO-7, DATADOI, V1
The 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... |

A tethersonde system by Vaisala (DigiCORA TT12) was applied to measure high-resolution vertical profiles of atmospheric variables (air temperature, relative humidity, wind speed and direction, and air pressure) up to 2000 meters. The instrumentation consisted of 7 m3 helium filled balloon for lifting sondes, an electrical winch, two sondes suspende... |
